LSD And Psilocybin
Both LSD and psilocybin are considered “classical hallucinogens” that interfere with the brain’s ability to interpret outside sensory input, often shifting people’s focus inward and producing spiritual revelations and a sense of transcendence. Scientists are testing whether they can combine the drugs with short-term therapy and counseling to bring about a new outlook in people with with several hard-to-treat psychiatric conditions.
Ketamine, a powerful sedative that also has hallucinogenic properties, was first developed in 1962 and later approved for use as an anesthetic for both human and animal patients. The drug has powerful dissociative effects; it causes users to feel that their minds are disconnected from their bodies. Clubbers began taking ketamine, or “Special K,” in the ‘70s and ‘80s for these out-of-body sensations. Recently, the drug has surged in popularity, especially in the U.K. and China.
MDMA, which combines stimulant effects of amphetamine with psychedelic effects, was invented back in 1912. It didn’t capture public attention until the ‘80s and ‘90s, when it gained notoriety as a “love drug” that heightened sexual experiences — and as a club drug that fueled raves. But, before that, some therapists in California were using the compound to get people to open up.
When the federal government classified marijuana as a Schedule I drug back in 1970, the drug was included in a category with other psychedelics, though it has both stimulant and depressant effects and doesn’t typically cause the same kind of profound hallucinations.
