Hallucinogens (LSD, ketamine, PCP)
Hallucinogens are a class of drugs that cause hallucinations—profound distortions in a person’s perceptions of reality. Hallucinogens can be found in some plants and mushrooms (or their extracts) or can be man-made, and they are commonly divided into two broad categories: classic hallucinogens (such as LSD) and dissociative drugs (such as PCP). When under the influence of either type of drug, people often report rapid, intense emotional swings and seeing images, hearing sounds, and feeling sensations that seem real but are not.

LSD/Acid is one of the most powerful mood-changing chemicals. It is a clear or white odorless material made from lysergic acid, which is found in a fungus that grows on rye and other grains. LSD has many other names, including Acid, Blotter, Dots, and Yellow Sunshine.
Ketamine/K/Special K/ is used as a surgery anesthetic for humans and animals. Much of the ketamine sold on the streets comes from veterinary offices. While available as an injectable liquid, manufacturers mostly sell it as a powder or as pills. Other names for ketamine include K, Special K, or Cat Valium.
Phencyclidine (PCP) was developed in the 1950s as a general anesthetic for surgery. It’s no longer used for this purpose due to serious side effects. While PCP can be found in a variety of forms, including tablets or capsules, liquid and white crystal powder are the most common forms. PCP has various other names, such as Angel Dust, Hog, Love Boat, and Peace Pill.
