Abstract
Abstract 47 undergraduate male volunteers were asked 2 questions relating to their use of marijuana and/or psychedelic drugs (e.g., LSD, mescaline, psilocybin) and were administered the Harvard Group Scale of Hypnotic Susceptibility, Form A (HGSHS:A). The HGSHS:A scores of Ss who had, at some time, taken any of these drugs averaged 2 points higher than scores of Ss who had not. Further research is needed to determine whether or not the relationship between drug use and hypnotizability is a causal one.
