Whether you are thinking about using drugs yourself or know someone else who is using them - it's a good idea to know the facts.

Some drugs are more dangerous than others. Class A drugs, including heroin, cocaine, crack, LSD and ecstasy are the most dangerous. These drugs are highly addictive and can cause serious problems with anxiety, paranoia, heart problems or convulsions. You can also die from an overdose.

Gases, glues and aerosols can cause instant death the first time they are tried. Drugs such as cannabis also affect co-ordination, increasing the risks of accidents especially if driving.

Drugs are also highly illegal. For example, if you are caught with a Class A drug such as ecstasy you could get up to seven years in custody. If you are under 18 you could be sent to a Youth Offender's Institution or another form of secure accommodation. Supplying someone else with ecstasy (including just sharing drugs) can get you life imprisonment and an unlimited fine.

Class B drugs, like speed, are also illegal. In January 2004, cannabis was reclassified from a Class B drug to a Class C drug. The purpose of this was to make it clear that experts knew that cannabis was harmful, but not as harmful as other Class B substances. Despite the change, it's still illegal to grow, possess or supply cannabis to another person. The maximum penalty for supplying and dealing in cannabis will stay at 14 years imprisonment.
