The study, from Saint Louis University School of Medicine studied 373 participants, of which 34 percent reported to have used marijuana before sexual activity, all of them being women. The results show that after combining cannabis and sex, overall sexual satisfaction was elevated.
The majority of the women reported an improvement in orgasm, decrease in pain, but no change in lubrication. The women who used marijuana before sexual activity had higher odds of reporting heightened orgasms compared to the women who didn’t use marijuana, and women who frequently used marijuana regardless of whether it was before or after sex, had much higher odds of reporting satisfactory orgasms.
The study concluded:
Marijuana appears to improve satisfaction with orgasm. A better understanding of the role of the endocannabinoid system in women is important, because there is a paucity of literature, and it could help lead to development of treatments for female sexual dysfunction.
