Cannabis Users Have Better Sex, According To Science

It sounds like a slogan you’d expect to see on a T-shirt or a bumper sticker, but it’s also a scientifically valid statement: Cannabis users have better sex lives.

Proof can be found in numerous studies, the latest of which appeared this month in the journal Sexual Medicine, and revealed that men who use marijuana more frequently tend to have slightly better sexual function, while also enjoying sex more than men who use cannabis less frequently or never at all[i].

The study authors surveyed 325 men, 71.4 percent of whom claimed to use cannabis at least six times a week. On average, these men performed better on the International Index of Erectile Function (IIEF) than those who use three to five times a week, once to twice a week, or never. In other words, the most regular users are also the most regular performers, and generally experience fewer mechanical failures in the bedroom.

Men who used weed more frequently also reported having stronger orgasms and greater intercourse satisfaction than those who consume less often. The majority of participants in the study said they tend to smoke rather than vape or use edibles, and always use THC-containing cannabis. However, the researchers found that the method of consumption and cannabinoid composition had no bearing on sexual performance or satisfaction.

In spite of these findings, the authors stress that cannabis shouldn’t be seen as a cure for sexual dysfunction, and insist that they are merely reporting the existence of an apparent relationship between frequent marijuana use and better sex. Having said that, it’s worth bearing in mind that this is not the first study to notice such a trend.

A paper that appeared last year in the Journal of Sexual Medicine, for example, found that two-thirds of people who have combined cannabis and sex experienced an increase in the intensity of their orgasms, with 73.8 percent reporting that marijuana enhanced their sexual satisfaction[ii]. Half of the women in this study also said that they found it easier to climax when using cannabis, though only 11.4 percent of men said the same – although this is perhaps unsurprising given that men generally need no help reaching orgasm.

Exactly how weed produces these effects is not fully understood, although it seems likely that certain elements of sexual function are mediated by the cannabinoid system, and can therefore be enhanced using cannabis. Evidence for this can be seen in a recent study involving non-copulating male rats, which are normal and healthy rodents that for some reason refuse to mate even when they come across sexually receptive females. After being treated with certain cannabinoids, however, half of the rats in the study finally made a move on a female and began mating[iii].

As always, it’s impossible to say for sure if the same treatment would work for humans experiencing sexual issues, although it’s always nice to come across a study that has a happy ending for the lab rats.
