There’s some good news for pot users out there, as a new study is claiming that people who smoke marijuana have sex more often than those who do not, although scientists are unsure of why. While weed users often claim that pot is a natural aphrodisiac, there isn’t much scientific research to back this up, until now.

The study, which was published in the Journal of Sexual Medicine, examined 50,000 people who participated in the annual survey by the Centers for Disease Control and Prevention between 2002 and 2015. Those surveys recorded how many times people smoked weed and how many times they’ve had sex in the last month.

They found that those who smoked weed daily had about 20 percent more sex than those who did not, which is a pretty significant difference. Women who consumed marijuana on a daily basis had sex about 7.1 times per month, and men did it 6.9 times per month, but those who did not smoke had sex 6 and 5.6 times per month, women and men respectively.

“Frequent marijuana use doesn’t seem to impair sexual motivation or performance. If anything, it’s associated with increased coital frequency,” said the study’s senior author, Michael Eisenberg, MD, assistant professor of urology at Stanford University Medical Center. The lead author is Andrew Sun, MD, a resident in urology.
