Men who smoke marijuana may have more problems achieving orgasm during sex than abstainers, according to a new Australian study.
New Scientist reported Aug. 24 that researchers from La Trobe University in Melbourne found that men and women who smoked marijuana daily were more likely to have had multiple sex partners than nonusers, but only the male users experienced performance problems in bed.
Marijuana-smoking men were more likely to have problems reaching orgasm, experienced premature ejaculation, and reached orgasm too slowly, researchers found.
Previous studies have also found a relationship between marijuana use and male sexual dysfunction.
The research was published in the Journal of Sexual Medicine.
