Turn On, Tune In, Get Healthy
Research into the health benefits of psychedelics, of course, largely dried up when the substances were criminalized in the late 1960s. Since then, research groups advocating study of the health benefits of psychoactive drugs have been petitioning governments around the world for changes to the law.
A study of peyote use among residents of a Navajo reservation (who are permitted by US law to use the drug for religious purposes) found that peyote is safer than previously believed. It also showed promise in preventing recovering alcoholics on the reservation from relapsing. Similar studies have been conducted in Russia, where access to some psychedelic drugs was legal until recently.
