"Although use of certain drugs like alcohol, methamphetamine or cocaine is associated with increased aggression and partner violence, use of psychedelics appears to have the opposite effect," says clinical psychology graduate student and study lead author Michelle Thiessen. "We found that among men who have used psychedelics one or more times, the odds of engaging in partner violence was reduced by roughly half. That's significant."

Psychedelic drugs act on serotonin receptors in the brain. Classic psychedelics include lysergic acid diethylamide (LSD), psilocybin (magic mushrooms), mescaline, and dimethyltryptamine (DMT). The effects vary but can produce mystical experiences and changes in perception, emotion, cognition and the sense of self. Classic psychedelics are not considered to be addictive.
