Many people feel relaxed after a few drinks. This is because alcohol is a depressant. Drink too much alcohol and you may well pass out for the same reason!
A few depressants, like alcohol, are taken recreationally by individuals who are looking to relax. In many scenarios, depressants can be used safely. However they can also be dangerous if used inappropriately. Many depressants are available only by prescription or are even illegal. So, what exactly are depressants?
What are Depressants?
The word ‘depressant’ comes from the root word depress. In relation to drugs, this term has nothing to do with feeling down or sad. In this context, ‘depress’ means to lower your level of activity and this is what a depressant drug does.
Depressants slow down the activity of the central nervous system (CNS) and the messages that are sent between the body and the brain. Alcohol is the most widely used legal depressant. Commonly used illegal depressants in the UK are cannabis and heroin. Many prescription drugs are also depressants, these include barbiturates and benzodiazepines (e.g. valium, temazepam).
Depressants can lower your level of awareness, decrease your heart rate, and slow down breathing. For these reasons, depressants are also known as ‘downers’.
The effects of depressants can change depending on the amount taken. Cannabis, for example, is normally considered a depressant, but when used in greater quantities it can act like a hallucinogen.
