Selected quotes.
Amphetamines
"This is a yellow-white powder which people call 'speed' or 'whiz' - people take this by mouth or sniff it ... Sometimes it is called Ice or Crystal and is smoked in a pipe."
"When somebody takes it (it) can make them try to do things that they can not - like climbing buildings or trees and a lot of people have been in accidents because of this."
Cannabis
"This is taken as black (sometimes dark brown) leaves, usually with some seeds mixed in, as a dark-coloured block or as a dark oily liquid ... It has a lot of different slang names like "pot" or "dope" or "wacky backy".
Ecstasy
"This is taken as a tablet ... The worst problem with ecstasy is that less than half of the tablets that people sell as ecstasy are actually ecstasy. Usually they are other drugs instead or they have other drugs or chemicals mixed in with them."
Heroin
"Names: 'Gear', 'Brown', 'H', 'Smack', 'Horse', 'Skag', 'Junk', 'Henry,' 'Harry', 'Elephant' ... This is a brown powder that can be "snorted" (inhaled through the nose) or smoked on a piece of hot tin foil but it is usually injected with a needle...
When people take it for the first time it makes them feel ill. After the first time it makes them feel dreamy and relaxed."
Magic Mushrooms
"The most dangerous thing about magic mushrooms it that you need to be an expert to be able to tell magic mushrooms from poisonous ones."
