Special K, also known as ketamine, is a dissociative anesthetic drug that has been in use for both medical and recreational purposes since the 1960s. It was first developed as a veterinary tranquilizer, but its use expanded to include human anesthesia in the 1970s. In the 1980s, the Special K drug became increasingly popular among club-goers and was used recreationally as a party drug due to its dissociative and hallucinogenic effects.
