Examples of psychoactive substances include alcohol, caffeine, nicotine, marijuana, and certain pain medicines. Many illegal drugs, such as heroin, LSD, cocaine, and amphetamines are also psychoactive substances. Also called psychotropic substance.
Why is alcohol psychoactive?
3.1 Brain (CNS Effects) – Different from other psychoactive substances like opioids there is no special alcohol receptor in the brain. A number of neurotransmitters are involved in mediating alcohol’s effects including GABA, glutamate, dopamine, opioids, serotonin, and noradrenalin, among others.
Alcohol is a psychotropic agent that depresses the central nervous system (CNS) basically via enhancement of GABAergic neurotransmission. GABA is the most important inhibitory neurotransmitter in the brain. Acute alcohol intoxication results in enhancement of inhibitory neurotransmitters (GABA) and antagonization of excitatory neurotransmitters (glutamate, dopamine, etc.) while the neurotransmitter function in alcohol withdrawal is the opposite (increased activity and release of excitatory, inhibition of inhibitory neurotransmitters).
Thus alcohol withdrawal results in an increased excitatory state in the brain, possibly leading to seizures or delirium. The rewarding, psychotropic effects of alcohol are in part mediated by dopamine, opioids, GABA, glutamate, and serotonin. There seems to be a special addiction memory in the brain which in part involves brain structures which are of relevance for physiologic reward processes and controlling of food and fluid intake and sexuality.
One of the key structures in the brain mediating these reward effects is the dopaminergil mesolimbic system including the nucleus accumbens. Activation of this system leads to positive reinforcement. Alcohol but also other psychotropic drugs are believed to act predominantly by interactions with neurons in these brain areas.
Alcohol also directly acts on neurons in the CNS. It alters the properties of lipids in the membrane of neurons but also has direct neurotoxic effects at least in higher concentrations. Chronic alcohol intake may result in cell damage and destruction of neurons in the brain but also in other regions of the body.
- Other alcohol-related factors such as vitamin deficiencies or malnutrition in general may contribute to the neurotoxic effects.
- Although alcohol-related cell loss can be found in all brain areas, the forebrain and the cerebellum are mostly effected in chronic alcoholics.
- To some extent cell losses in the CNS can be visualized in vivo by modern neuroradiological techniques such as cranial computertomography scans or NMR.

What is the psychoactive ingredient in alcohol?
In chemical terminology, alcohols are a large group of organic compounds ” derived from hydrocarbons and containing one or more hydroxyl (-OH) groups. Ethanol (C2H5OH, ethyl alcohol) is one of this class of compounds, and is the main psychoactive ingredient in alcoholic beverages.
By extension the term “alcohol” is also used to refer to alcoholic beverages. Ethanol results from the fermentation of sugar by yeast. Under usual conditions, beverages produced by fermentation have an alcohol concentration of no more than 14%. In the production of spirits by distillation, ethanol is boiled out of the fermented mixture and re-collected as an almost pure condensate.
Apart from its use for human consumption, ethanol is used as a fuel, as a solvent, and in chemical manufacturing. Absolute alcohol (anhydrous ethanol) refers to ethanol containing not more than 1% by mass of water. In statistics on alcohol production or consumption, absolute alcohol refers to the alcohol content (as 100% ethanol) ’80s, of alcoholic beverages.
Methanol (CH3 OH), also known as methyl alcohol and wood alcohol is chemically the simplest of the alcohols. It is used as an industrial solvent and also as an adulterant to denature ethanol and make it unfit to drink (methylated spirits). Methanol is highly toxic; depending on the amount consumed, it may produce blurring of vision, blindness, coma, and death.
Other non-beverage alcohols that are occasionally consumed, with potentially harmful effects, are isopropanol (isopropyl alcohol, often in rubbing alcohol) and ethylene glycol (used as antifreeze for automobiles). Alcohol is a sedative/hypnotic with effects similar to those of barbiturates.
- Apart from social effects of use, alcohol intoxication may result in poisoning or even death; long-term heavy use may result in dependence or in a wide variety y of physical and organic mental disorders.
- Disorders due to use of alcohol are classified as psychoactive substance use disorders in ICD-11 ( 6C40 ).
WHO Lexicon of alcohol and drug terms
Is coffee a type of psychoactive?
What is caffeine? – Caffeine is a psychoactive (mind-altering) drug that affects how we think and feel. It is a stimulant that speeds up our breathing, heart rate, thoughts and actions. Caffeine is found in the seeds, leaves and fruit of certain shrubs, including coffee and tea plants.
What makes a drug psychoactive?
Psychoactive drugs are substances that, when taken in or administered into one’s system, affect mental processes, e.g. perception, consciousness, cognition or mood and emotions. Psychoactive drugs belong to a broader category of psychoactive substances that include also alcohol and nicotine.
“Psychoactive” does not necessarily imply dependence-producing, and in common parlance, the term is often left unstated, as in “drug use”, “substance use” or “substance abuse”. Production, distribution, sale or non-medical use of many psychoactive drugs is either controlled or prohibited outside legally sanctioned channels by law.
Psychoactive drugs have different degrees of restriction of availability, depending on their risks to health and therapeutic usefulness, and classified according to a hierarchy of schedules at both national and international levels. At the international level, there are international drug conventions concerned with the control of production and distribution of psychoactive drugs: the 1961 Single Convention on Narcotic Drugs, amended by a 1972 Protocol; the 1971 Convention on Psychotropic Substances; the 1988 Convention Against Illicit Traffic in Narcotic Drugs and Psychotropic Substances.
- The use of psychoactive drugs without medical supervision is associated with significant health risks and can lead to the development of drug use disorders.
- Drug use disorders, particularly when untreated, increase morbidity and mortality risks for individuals, can trigger substantial suffering and lead to impairment in personal, family, social, educational, occupational or other important areas of functioning.
Drug use disorders are associated with significant costs to society due to lost productivity, premature mortality, increased health care expenditure, and costs related to criminal justice, social welfare, and other social consequences. About 270 million people (or about 5.5% of global population aged 15-64) had used psychoactive drugs in the previous year and about 35 million people are estimated to be affected by drug use disorders (harmful pattern of drug use or drug dependence).
- It is estimated that about 0.5 million death annually are attributable to drug use with about 350 000 male and 150 000 female deaths.
- Opioid-related deaths, largely due to synthetic opioids, have recently changed the mortality trends in some high-income countries,
- More than 42 million years of healthy life loss (DALY) were attributable to drug use in 2017; that is about 1.3% of the global burden of disease.
It is estimated that worldwide there are almost 11 million people who inject drugs, of whom 1.4 million live with HIV and 5.6 million – with hepatitis C. Since its creation, WHO has played an important role within the UN system in addressing the world drug problem.
prevention of drug use and reduction of vulnerability and risks;treatment and care of people with drug use disorders;prevention and management of the harms associated with drug use;access to controlled medicines; andmonitoring and evaluation.
Target 3.5 of UN Sustainable Development Goal 3 sets out a commitment by governments to strengthen the prevention and treatment of substance abuse. Several other targets are also of particular relevance to drug policy-related health issues, especially target 3.3, referring to ending the AIDS epidemic and combating viral hepatitis; target 3.4, on preventing and treating noncommunicable diseases and promoting mental health; target 3.8, on achieving universal health coverage; and target 3.b, with its reference to providing access to affordable essential medicines.
In April 2016, the thirtieth Special Session of the UN General Assembly (UNGASS) reviewed the progress in the implementation of the 2009 Political Declaration and Plan of Action on International Cooperation Towards an Integrated and Balanced Strategy to Counter the World Drug Problem and assessed the achievements and challenges.
In resolution S-30/1, the General Assembly adopted the outcome document of the special session on the world drug problem entitled “Our joint commitment to effectively addressing and countering the world drug problem”. The UNGASS marked a shift in the overall drug policy discourse to highlight the public health and human rights dimensions of the world drug problem and to achieve a better balance between supply reduction and public health measures.
Why do people try to get drunk?
A lcohol is a very simple molecule with incredibly complex effects. Although I already knew a bit about the neurobiology of alcohol, I just spent an afternoon reading a dense journal article that described roughly 50 different neural mechanisms it affects.
- After which I felt like I needed a drink.
- It’s widely known that alcohol reduces stress temporarily, and many people use it for just that purpose.
- It reduces stress by increasing the uptake of a neurotransmitter called GABA, the brain’s primary inhibitory molecule.
- And by “inhibitory” I don’t mean that it makes you feel inhibited.
Quite the opposite, of course.) By sending more GABA to your brain cells, alcohol works much like common tranquillising drugs such as Valium and Xanax. That’s why you start to stumble and slur if you drink too much. But alcohol acts on many other neurotransmitters too.
I’ll mention three important ones and show how they contribute to the joys of inebriation. While alcohol increases GABA, it reduces the uptake of glutamate, the brain’s premier excitatory molecule, Less excitation and more inhibition? That sounds like simple summation, but GABA and glutamate have different effects on different brain regions, and that’s where things get complicated.
In the prefrontal cortex, the part of the brain you use for thinking and planning, the net effect is inhibition. That’s why your judgment is flawed, your decision-making is set to “whatever” and your ability to see things from any perspective other than your own approaches nil.
The remarkable side effect of this general dimming is that your thoughts seem amazingly clear – which is nice – while in reality they are just amazingly limited. Meanwhile, GABA is also busy turning off the brakes on a system that releases dopamine, the molecule that takes centre stage in all varieties of addiction.
What’s that again? Well, when you take off the brakes, the car starts to move. So what you get is a stream of dopamine coursing into the striatum (or reward system), the brain part that generates desire, anticipation and (once you’ve finally brought the glass to your lips) pleasure.
- So far, you’ve got physical relaxation, which diminishes stress, reduced judgment, allowing you to talk and behave however you want, and stimulation of the brain’s reward system, which makes you feel like something nice is about to happen.
- But the fourth neurotransmitter tops the bill: opioids.
- Sometimes called endorphins or internal opiates, they get released by alcohol too.
Everyone knows that opiates feel good, but did you know that you can get your opiates legally by downing a stiff drink? The American martini – which consists of three ounces of gin and little else – feels particularly nice for a very simple reason. The faster the alcohol goes in, the more internal opiates get released. Aaaaaahhhh! A dry martini, with its three ounces of gin. Photograph: Alamy Given all the things that make up an alcohol high, it shouldn’t be surprising that inebriation feels different to different people, feels different from the first to the last drink, and definitely feels different once it becomes hard to stop.
- People who carry around a lot of stress drink to relax.
- People who spend a lot of energy controlling their impulses drink in order to let themselves go.
- The first drink of the night excites you, the last drink of the night sedates, and that isn’t nearly as much fun.
- College kids indulge in binge-drinking because they’re still bright-eyed novices when it comes to taking chemicals that alter their mood – the more the merrier.
Twenty years later, they may drink to feel less, not more, because life has become oppressive, and anxieties seem ready to spring from every train of thought. But once people become addicted to alcohol, as many do, the fun of the high is eclipsed by two opposing fears.
- The fear of going without, versus the fear of being unable to stop.
- That clash of concerns comes from several sources.
- First there are the unpleasant bodily effects that plague big drinkers when they stop for a few hours or, worse, a few days.
- Add to that the emotional emptiness, depression, and increased stress responsiveness that overcome the drinker’s mood at the same time.
Taken together, these effects make up what George F Koob calls the dark side of addiction, But I think the real bogeyman, the unbeatable Catch-22 when it comes to alcohol and other drugs, is the realisation that the thing you rely on to relax is the very thing that stresses you out the most.
It’s hard to find a way out of the recurrent cycle of anxiety and temporary relief, over and over, and that’s the epitome of a losing battle. People like to get drunk because alcohol smacks your brain around in a number of ways that feel pleasant, or at least different, or at the very least better than going without.
And that’s really how all mood-altering drugs work. Which is generally OK, because recreational drug use, including drinking, doesn’t lead to addiction for most people, But for those who get caught, the fun soon disappears. When the fun stops. Photograph: Alamy Drugs, including alcohol, fashion neural habits: get it, take it, lose it, then get it again. And those habits narrow the brain’s focus to a very singular goal, at the expense of everything else. The striatum – the brain’s reward system – is responsible, not just for pleasure, but more seriously, for feelings of desire.
- And desire isn’t fun, unless you’re just about to get whatever it is you want.
- Then, the more you get it, the more your striatum gets tuned by that surge of dopamine, modifying its synaptic wiring a little bit at a time until other goals just don’t count for much.
- But alcohol has one advantage over drugs like heroin and cocaine.
It’s legal, and socially sanctioned. In fact drinking has become deeply enmeshed with themes of social engagement, joyful celebrations and all the rest of it. Drinking doesn’t make you a bad person – in fact it seems to put you in good company and thereby make you a good person – if you can resist its addictive lure.
Why do we get drunk to get drunk?
In the brain, alcohol acts as a depressant, slowing brain responses. This is what causes the feeling of being ‘drunk.’ Using safer drinking practices can help your body process the alcohol you drink and avoid severe intoxication.
Is Rum psychoactive?
Abstract – Studies of alcohol and congener effects on the aggressive behavior of fish have been reviewed. It is clear that alcohol has both depressing effects at very low and very high doses and a facilitating effect at moderate doses. Congener effects as they are present in bourbon and in rum appear to have aggression-inhibiting effects.
What is the most common psychoactive substance *?
Caffeine is the most widely used psychoactive substance in the world. In Western society, at least 80 per cent of the adult population consumes caffeine in amounts large enough to have an effect on the brain.
Is tea a psychoactive drug?
At its core, tea is a potent herbal drug with a cocktail of natural stimulants and mood enhancers far more complex in effect than coffee. The big psychoactive compounds in tea are Caffeine, L-Theanine, GABA and Catechins. Caffeine (in a fixed state) gives you a sustained energy boost and mental awakening.
Could caffeine be a drug?
Caffeine is a stimulant drug, which means it speeds up the messages travelling between the brain and the body. It’s found in the seeds, nuts and leaves of a number of different plants, including: Coffea Arabica (used for coffee)
Is aspirin a psychoactive drug?
Abstract – Antiplatelet substances, generally aspirin, have become widely used for secondary prevention of ischemic heart disease. Used in relatively small doses, it is generally assumed that aspirin has no psychoactive effect. The present study took advantage of a sample of 174 males undergoing coronary angiography to see if regular aspirin use as prophylactic therapy for ischemic heart disease was associated with one or more of a number of measures of emotional distress.
Aspirin use was found to be associated with less depression and anxiety or worry, as reported by the patient and as perceived by a significant other. Despite a significant association of aspirin use with the presence of documented coronary artery disease, the association of aspirin use and diminished distress could not be accounted for by the previously observed high prevalence of depressed/anxious individuals among patients with negative or nominal results on angiography, or by a number of other demographic or clinical variables such as age and socioeconomic status.
Although only correlational in nature, present results raise the question of whether aspirin may have a beneficial mood-modulating effect.
Are antidepressants a psychoactive drug?
Antidepressants: misnamed and misrepresented Modern evidence reveals that there is little difference between antidepressants and placebo for the treatment of depression. This is the message of Khan and Brown’s review () of antidepressant research. In fact, older studies came to the same conclusion.
In 1969, the authors of a comprehensive review commissioned by the U.S. National Institute of Mental Health concluded that “in well-designed studies, the differences between the effectiveness of antidepressant drugs and placebo are not impressive” (), p.19). Problems with the evidence for antidepressants go even deeper than Khan and Brown suggest, however.
Not only does this evidence show that these drugs are little different from placebo, but also that there are no grounds to believe they have specific effects that would justify their classification as “antidepressants”. Like other drugs used for mental health problems, drugs classed as antidepressants are psychoactive substances.
Psychoactive substances are drugs that enter the brain and by doing so modify normal thoughts, emotions and behaviours. Recreational drugs have psychoactive properties that some people find pleasant or exciting, but other drugs – including antipsychotics, anticonvulsants and antidepressants – have psychoactive effects that are less appealing.
The psychoactive effects of individual antidepressants vary in strength and character, with the effects of some, such as the selective serotonin reuptake inhibitors (SSRIs), being weak and subtle, whereas the effects of others are more profound (e.g., the tricyclics).
- The fact that antidepressants are psychoactive substances has major implications for the interpretation of placebo-controlled trials.
- Firstly, the use of a psychoactive substance will inevitably impact on the experiences and emotions captured by depression rating scales.
- The sedative effects of antidepressants, such as the tricyclics and newer drugs like mirtazapine, for example, are likely to reduce the degree of agitation, anxiety and insomnia experienced by people with depression.
These symptoms feature strongly in measurement scales. Changes in sleep alone can account for up to 6 points on the Hamilton Rating Scale for Depression, for example, whereas typical antidepressant-placebo differences are around 2 to 3 points (,). Moreover, psychoactive effects may impact in varied ways on thoughts.
- Secondly, the psychoactive effects of antidepressants, along with the physical modifications they produce (both commonly referred to as “side effects”, although this is misleading since an independent, therapeutic effect has not been established), will infringe the double blind design.
- Some of the participants allocated to the active drug will be able to detect that they have received the real drug because of the physical or mental changes the drug produces, especially since they are provided with detailed information on possible side effects.
Thus, it has been shown in many placebo-controlled trials of drugs used for mental health problems that participants can guess what they have received better than chance (). In this situation, people allocated to the active drug are likely to have enhanced expectations of the effectiveness of therapy, and people who suspect they are taking placebo may have unduly negative expectations.
Both of these factors may create or exaggerate a difference between antidepressants and placebo. Unless the psychoactive effects of antidepressants are somehow discounted, differences between antidepressants and placebo cannot be interpreted as providing evidence that those drugs have a specific “antidepressant” effect.
Indeed, it transpires that most drugs with psychoactive effects – including many antipsychotics, benzodiazepines, stimulants, buspirone and opiates () – produce the same changes as so-called antidepressants in randomized trials in people diagnosed with depression.
- Moreover, antidepressants themselves come from a wide array of chemical classes, and produce diverse pharmacological effects.
- Unsurprisingly, it seems that the experience of taking some sort of mind-altering substance produces a slightly different result from taking an inert placebo, when you attempt to measure people’s thoughts and feelings (,).
If we accept this model, we need to ask whether the psychoactive effects that antidepressants or other drugs produce might logically be useful in people with depression. There may, for example, be a role for temporary use of drugs with sedative properties to manage insomnia, anxiety and agitation in people who experience these symptoms, balancing proper evidence of benefits against adverse effects, including risks of dependence.
- There has been some debate as to whether the SSRIs and related antidepressants produce a state of emotional suppression or disengagement.
- Antipsychotics are well known for dulling emotions, but the effects of SSRIs are likely to be more subtle.
- Evidence from converging sources now suggests that SSRIs and other newer antidepressants do have this property, and that it is associated with recognized side effects, such as loss of libido and sexual impairment (–).
Many people dislike this state of emotional numbing but, in theory, some may find it useful to manage an intense emotional crisis. Again, we need evidence to explore whether this particular effect produces any tangible improvement in people suffering from depression, and whether people find it acceptable or not.
- For decades now people have been told that depression is a chemical imbalance and that antidepressants work by correcting that imbalance.
- This view is not supported by evidence, and is misleading as to the nature and effects of antidepressant drugs.
- We need to recognize that antidepressants are psychoactive substances, we need more data on the nature of the varied psychoactive effects they produce, and we need to explore whether giving drugs that produce an artificially altered emotional state is a useful and acceptable intervention for people with depression.1.

Is there a difference between psychoactive and psychotropic?
Examples of psychotropic substances include alcohol, caffeine, nicotine, marijuana, and certain pain medicines. Many illegal drugs, such as heroin, LSD, cocaine, and amphetamines are also psychotropic substances. Also called psychoactive substance.
Why are people friendlier when drunk?
Drinking alcohol is associated with aggressive behaviour, accidents and ill health. Yet many of us choose to drink socially. This may reflect alcohol’s actions on specific brain circuits which make us feel euphoric and less anxious. Alcohol may also make us more empathic and cause us to see other people as more attractive,
- But why do these reactions occur and are the positive effects of alcohol expressed towards everybody we interact with? Alcohol is a drug, one of the three most commonly used in the world, along with nicotine and caffeine.
- When we drink, the alcohol binds to a specific type of receptor in the brain and boosts the activity of a natural brain chemical called GABA.
The effect the alcohol has on us depends in large part on the dose, and the location of these GABA receptors within the brain. Early on in a drinking session, the alcohol acts on GABA systems to boost the levels of dopamine, the brain’s reward chemical.
- This gives a sense of well-being and a sense of mild euphoria.
- Alcohol also acts on GABA receptors to impair the activity of the brain circuits that make us feel anxious and, at higher doses, alcohol inactivates a second set of brain circuits that control fear.
- So threatening stimuli no longer seem quite so scary.
Alcohol also compromises our ability to compute risk so that situations we would normally shy away from may now seem quite inviting. Are you drunk? Gift by Shutterstock All of this points to alcohol as a facilitator of social interactions. As well as making us more empathic, laboratory studies have also shown that drinking alcohol can make us trust others more and make us temporarily more generous.
On the other hand, heavy drinking is associated with violent behaviour. This situation, however, is complex. Laboratory studies have shown that alcohol increases aggression. For example, it increases the willingness with which individuals will administer electric shocks to others, However, this effect seems to be largely restricted to those who are intrinsically aggressive in the first instance.
Don’t try this at home. Equally, alcohol can corrupt our ability to understand the intentions of others. The brain contains specific circuits, which connect parts of the prefrontal cortex, amygdala and temporal parietal junction, that handle our social cognitive abilities.
So our ability to understand somebody else’s mental perspective and their motivations for acting in a certain way become unreliable. Very big doses of alcohol can leave the functioning of these circuits so compromised that individuals can appear to be as impaired as patients with some forms of dementia,
This is quite a disturbing thought given the number of people who end up in this state in city centres at the end of a good night out. She’s definitely pleased to see me.J.K. Califf, CC BY-SA Alcohol also impedes our ability to accurately interpret emotional expressions in faces. As we drink, we have a tendency to erroneously assume that some facial expressions of negative emotions are happy, and we find it particularly difficult to identify sad and angry faces.
- This leaves us prone to making embarrassing social errors.
- One important, but often overlooked, aspect of alcohol’s effect on social functioning relates to how we perceive members of our in and out-groups.
- Alcohol appears to encourage us to bond to members of our in-groups,
- However, this may come at the cost of the way we treat people outside of these groups.
Similarly, alcohol makes members of our ethnic in-group appear more attractive but this effect does not extend to members of other ethnic groups. It must be emphasised that the effects described so far are potentially reversible once the drinker has sobered up.
However, chronic heavy drinking can lead to brain damage and irreversible cognitive impairments, especially poor memory function, and psychiatric problems including depression, psychoses, anxiety and suicide. So overall, alcohol may be a friend, and indeed make us friendlier, but only to a select group of people – and they may not always reciprocate.

Is it bad to get really drunk?
Overview People in the United States like to drink. According to a 2015 national survey, more than 86 percent of people ages 18 and older say they’ve had alcohol at some point in their lifetime. More than 70 percent had an alcoholic drink in the past year, and 56 percent drank in the past month.

The more alcohol you drink, the stronger the effects of alcohol on the body. Being very drunk can be dangerous. It can cause seizures, dehydration, injuries, vomiting, coma, and even death. It can be helpful to know the signs of being drunk so you can avoid possible harm to yourself by continuing to drink.
Why does alcohol make the brain release dopamine?
Alcohol’s Actions as a Reinforcer: Dopamine’s Role – Although numerous studies have attempted to clarify dopamine’s role in alcohol reinforcement by manipulating dopaminergic signal transmission, these investigations do not allow any firm conclusions (for a review, see Di Chiara 1995 ).
The comparison of alcohol’s effects with the effects of conventional reinforcers, such as food, however, provides some clues to dopamine’s role in mediating alcohol reinforcement. Palatable food activates dopaminergic signal transmission in the NAc shell, for example, by exerting specific sensory (e.g., taste, or gustatory) stimuli.
Orally administered alcohol similarly activates taste receptors, thereby increasing dopamine release in the NAc. In contrast to food, however, alcohol also can modify the function of dopaminergic neurons more directly by entering the brain. Accordingly, oral alcohol administration influences dopamine release in the NAc both through its gustatory properties (i.e., as a conventional reinforcer) and through its direct actions on the brain (i.e., as a drug reinforcer).
- Consistent with this hypothesis, two peaks of dopamine release occur in the NAc.
- The first peak results from the alcohol-related gustatory stimuli; the second results from alcohol’s actions within the brain.
- Consequently, alcohol-induced direct activation of dopaminergic signal transmission might reinforce the motivational properties of the gustatory stimuli associated with alcohol.
As a result of this mechanism, the alcohol-related gustatory stimuli acquire strong incentive properties (i.e., they become motivational stimuli that induce the drinker to seek even more alcohol). Similarly, appetitive stimuli related to alcohol (e.g., extrinsic stimuli, such as the sight of a certain brand of an alcoholic beverage or the sight of a bar) also acquire incentive properties and promote the search for and consumption of alcohol.

What is the psychotropic effect of alcohol?
INTRODUCTION – According to a Canadian study published in 2012, 80% of males and 74% of females aged 15 years or older reported consuming alcohol within the past year (data for 2010).1 Alcohol interacts with many over-the-counter and prescription drugs, including psychotropic medications such as antidepressants, anxiolytics, and antipsychotics, which are commonly prescribed for the treatment of mental health disorders.
The mechanism by which alcohol interacts with medications can be pharmacokinetic or pharmacodynamic in nature. Acute alcohol ingestion may inhibit the enzymes responsible for drug metabolism, increasing the risk of adverse effects from a medication by prolonging and enhancing its availability. Conversely, chronic alcohol ingestion may induce certain enzymes, resulting in enhanced drug elimination and diminished therapeutic effects.
Medications can also alter the metabolism of alcohol, increase alcohol-related adverse effects, and lower the threshold for intoxication. When combined with psychotropic medications, alcohol may potentiate the drugs’ inhibitory effects on the central nervous system, which can impair an individual’s ability to function.2 It has been estimated that alcohol–medication interactions may be a factor in at least 25% of all emergency room visits.3 Several studies have evaluated patterns of use of alcohol and interacting medications in various populations.4 – 7 In a population-based study in the United States, Breslow and others 8 found that 41.5% of adult current drinkers used alcohol-interactive medications, the most commonly used medication classes being cardiovascular agents and central nervous system agents.
Although literature about the interactions between psychotropic medications and alcohol in Canada is sparse, one Canadian study reported the prevalence of heavy alcohol consumption among benzodiazepine users in the previous week as 7.2%; current benzodiazepine users were less likely than non-current users to have recently consumed any alcohol.9 Psychotropic medications are often prescribed for long-term treatment of chronic mental health conditions; as such, it is important for patients to understand the serious negative consequences and risks that may result from alcohol–drug interactions.
Health care professionals, such as physicians, nurses, and pharmacists, may give patients information related to their medications. However, it is unknown whether patients are aware of potential interactions with alcohol or whether they follow any advice that is provided.
Why is alcohol a performance enhancing drug?
Athletes work hard and are determined to be the best. Consider these questions before making decisions about drinking as an athlete.
How important is my sport to me? How important is drinking or partying to me? How important is it that I perform to the best of my ability? How will drinking affect my ability to perform? How will my body feel if I drink? How will I feel if I don’t drink? Will I violate team, University, or state laws and regulations if I choose to drink? What can I do instead of drinking heavily? How can I stay motivated to stick with my decision?
Athletic Performance & Mental Sharpness
Alcohol is not considered to be a performance enhancing substance. It slows the body down and can have effects up to one day after consumption. Alcohol influences balance, reaction time, fine and complex motor skills, and information processing. Drinking alcohol the night before or after a game can affect your performance. Hangovers can result in symptoms of headaches, nausea, diarrhea, fatigue, dehydration, and body aches that can diminish athletic performance. There is no benefit from alcohol use for sport performance.
