Does using marijuana increase the likelihood of using hallucinogens?
“Exposure opportunity” has been found to be a mechanism which makes individuals more likely to use alcohol, tobacco or other drugs. A large epidemiological study has shed light on an observed association between the use of marijuana and hallucinogens. Youths who had used marijuana were more likely than nonusers to have the opportunity to use hallucinogens. Once an opportunity to use hallucinogens occurred, marijuana users were more likely than nonusers to start using hallucinogens.
