What are hallucinogens?

Hallucinogens are a group of drugs that work on the brain to affect the senses and cause hallucinations – seeing, hearing, smelling, tasting or touching things that do not exist. Hallucinogens are sometimes called psychedelic drugs, trips, magic mushrooms, LSD or acid.

Lysergic acid diethylamide

(C20G25N3O)

Some hallucinogens occur naturally in trees, vines, seeds, fungi (eg psilocybin or magic mushrooms) and leaves. Others are made in laboratories by mixing different chemical substances (trips, LSD, acid). Some drugs, such as cannabis and ecstasy, can cause hallucinogen-like effects when used in high doses or in certain ways. Using hallucinogens is often called tripping.

Physical effects can include

  • muscles twitching
  • feeling numb
  • feeling sick or vomiting
  • poor coordination

Effects depend on...

​What hallucinogens do to you depends on how much you take, your height and weight, your general health, your mood, your past experiences with hallucinogens, whether you use hallucinogens on their own or with other drugs, whether you use alone or with others, at home or at a party, etc.
