This is a guide to the properties, effects and symptoms of all the main "street" drugs, from hashish to ecstasy and the ever-evolving range of chemical spin-offs, and how to cope with the effects when they run out of control, both for the taker and the passer-by. The book is intended to give guidance not only on recognition, but on first-aid treatment of drug abusers. It should also be useful to parents and concerned friends, or relatives of drug users and to users themselves. Practical advice is given both for victims and observers of drug abuse.
