Glossary Of Terms - H
HALLUCINOGENS - are drugs that produce hallucinations (distortion in perception of sights and sounds) and disturbances in emotion, judgment and memory. Hallucinogens are unpredictable and can cause intensified and mixed-up sensations. Cannabis, ecstasy, LSD, magic mushrooms and skunk can all be classed under this term.
Hepatitis C - is a blood-borne infectious disease that is caused by the Hepatitis C virus, affecting the liver. The virus is spread by blood-to-blood contact, and the infection is often asymptomatic.
HEROIN - is a natural opiate made from morphine (morphine is extracted from the opium poppy). Like many drugs made from opium, including synthetic opioids (e.g. methadone) heroin is a very strong painkiller. 'Street' heroin sold as 'brown' is sometimes used by clubbers as a chill out after a big night out. Brown is still heroin but some people mistakenly think it's not as addictive.
HIV - human immunodeficiency virus. HIV is a retrovirus that causes AIDS by infecting helper T cells of the immune system. The most common type, HIV-1, is worldwide, whilst HIV-2 is primarily confined to West Africa.
