Depressant substances reduce arousal and stimulation. They do not necessarily make a person feel depressed. They affect the central nervous system, slowing down the messages between the brain and the body.
They can affect concentration and coordination. They slow down the person’s ability to respond to unexpected situations. In small doses they can cause a person to feel more relaxed and less inhibited. In larger doses they can cause drowsiness, vomiting, unconsciousness and death.
How depressants are used depends on the specific type, for example alcohol is drunk and benzodiazepines are usually swallowed but can also be injected. Generally speaking, depressants can be swallowed, drunk as a beverage, injected, snorted or inhaled.
There is no safe level of drug use.
Use of any drug always carries some risk. It’s important to be careful when taking any type of drug.
Depressants affect everyone differently, based on:
The onset and effects of depressants vary according to the type and specific chemical. Some depressants may work instantly, with effects only lasting for a short time (such as inhalants), while other depressants may take longer for the effects to start and the duration of effects may last longer.
In general, when small to low doses of depressants are taken, the following effects may be experienced:
Use of depressants is likely to be more dangerous when:
The chemical composition of GHB/GBL is highly variable. It’s very easy to take too much GHB: the difference between the amount needed to get high and the amount that causes an overdose can be hard to judge. Use of any drug always carries some risk, however, if you choose to take it, always try a small test amount first.
If drinking alcohol, stay hydrated and have something to eat before and while drinking.
People who use depressants regularly can develop dependence and tolerance to them. Tolerance means they need to take larger amounts of depressants to get the same effect. Dependence on depressants can be psychological, physical, or both. People who are dependent on depressants find that using the drug becomes far more important than other activities in their life. They crave them and find it very difficult to stop using them. People who are psychologically dependent on depressants may find they feel an urge to use them when they are in specific surroundings or socialising with friends. Physical dependence occurs when a person’s body adapts to the depressants and gets used to functioning with the depressant present.
