Are Hallucinogens Harmful To Your Health?

What are hallucinogens?

Hallucinogens are psychedelic or mind-expanding drugs that cause intense changes in a person’s perception of reality. They include any drugs that cause a person to have visual or auditory hallucinations in which they see or hear things that aren’t real. Commonly used hallucinogens include LSD, PCP, mushrooms and Ecstasy (MDMA).

What does a hallucinogen look like?

Hallucinogens are a category that many illicit drugs fall into, so they appear in many different forms. They can be sold as pills, liquid or on absorbent paper. Some hallucinogens occur naturally in fungi and other types of plants, such as peyote and psilocybin (found in mushrooms). Peyote is cut from the root of the peyote cactus and sold as a dried out, disc-shaped button. Mushrooms containing psilocybin can be sold fresh or dried.

How are hallucinogens used?

Hallucinogens can be used in a variety of ways, including orally, dissolving them in liquid to drink, snorting, injection or smoking.
