Drugs
- A drug is any substance which alters the body's function, other than food or water.
- There is no safe level of illicit drug use.
- Psychoactive drugs affect the central nervous system and alter a person's mood, thinking and behaviour.
A drug is any substance (with the exception of food and water) which, when taken into the body, alters the body's function either physically or psychologically.
Drugs may be legal (for example alcohol, caffeine or tobacco) or illegal (for example cannabis, ecstasy, cocaine or heroin).
What is a psychoactive drug?
Psychoactive drugs affect the central nervous system and alter a person's mood, thinking and behaviour.
Psychoactive drugs may be divided into 4 categories.
Depressants are drugs that decrease alertness by slowing down the activity of the central nervous system, for example:
- heroin
- alcohol
- analgesics.
Stimulants are drugs that increase the body's state of arousal by increasing the activity of the brain, for example:
- caffeine
- nicotine
- amphetamines.
Hallucinogens are drugs that alter perception and can cause hallucinations, such as seeing or hearing something that is not there, for example:
- lysergic acid diethylamide (LSD)
- magic mushrooms.
Other drugs fall outside these categories, as they may have one or more of these properties. For example cannabis has depressive, hallucinogenic and stimulant properties.
People use drugs for a variety of reasons. Young people often use drugs for the same reasons that adults do. Some of these include:
- to have fun
- to relax and forget problems
- to gain confidence
- to socialise
- out of curiosity
- as a form of escapism
- to lessen inhibitions
- to remove personal responsibility for decisions
- to celebrate or commiserate
- to relieve boredom and stress
- self-medication to cope with problems.
Friends, parents, older brothers and sisters and the media can also have some influence over a young person's decision to use drugs.
