Hallucinogens change the way the brain interprets time, reality and the environment around the user. They also affect the way the user moves, reacts to situations, thinks, hears and sees. The user may think they are hearing voices, seeing images and feeling things that don’t exist.
Hallucinogens are illegal to buy, sell or possess.
Using hallucinogens can cause an increase in heart rate and blood pressure, lung and heart failure or coma.
The body can quickly form a tolerance, requiring the user to use more to get the same effect.
Hallucinogens can cause flashbacks. Effects of the drugs, including hallucinations, can occur weeks, months or years after use.
