Some hallucinogens can be found in plants. Mescaline comes from a cactus called peyote. And certain mushrooms, also known as “magic” mushrooms, are hallucinogens.
But many hallucinogens are chemicals that don’t occur in nature. Some examples are:
- LSD, also called acid
- MDA, also called the “love drug,” related to the stimulant amphetamine
- MDMA, known as ecstasy, also related to amphetamine
- PCP, often called angel dust
