Drug facts

There are lots of different types of drugs. Some drugs are prescribed by a doctor for illnesses but when people talk about drugs they usually mean drugs that are illegal or unsafe.

There are the three main types of drugs – depressants, hallucinogens and stimulants. These all have different effects on your body and brain and you can never be completely sure how you will react to them which is what makes drugs so dangerous.



Generally, depressants (such as cannabis) slow you down making you feel chilled out and relaxed – potentially to the point where your breathing and heart rate slow down to a fatal level.



Stimulants (such as ecstasy) bring you up increasing your alertness and possibly the pressure on your heart risking heart failure.



Hallucinogens (such as LSD) distort your senses changing the way you respond to sights, sounds and touch which could be pleasurable or frightening resulting in negative psychological effects.

Each particular drug within the 3 broad categories has its own specific effects and risks.
