Women Who Use Marijuana More Often Have Better Sex, Study Says

Among women who enjoy marijuana, there’s no shortage of anecdotal evidence that adding a bit of cannabis can bring a thrill to the bedroom, and in states where the drug is legal, marketers have capitalized on that claim. THC-infused lubricants promise increased arousal and better orgasms, and some sexual health advocates have built entire careers on cannabis-enhanced intimacy. But is there anything behind the hype?

While researchers are still trying to tease out the precise relationship between cannabis and sex, a growing body of evidence indicates the connection itself is very real. The latest study, which asked women who use marijuana about their sexual experiences, found that more frequent cannabis use was associated with heightened arousal, stronger orgasms and greater sexual satisfaction in general.

“Our results demonstrate that increasing frequency of cannabis use is associated with improved sexual function and is associated with increased satisfaction, orgasm, and sexual desire,” says the new study, published last week in the journal Sexual Medicine.

“Increased cannabis use was associated with improved sexual desire, arousal, orgasm, and overall satisfaction.”

To reach their conclusions, the team analyzed online survey results from 452 women who responded to an invitation distributed at a chain of cannabis retail stores. Researchers asked respondents about their cannabis use and had each fill out a Female Sexual Function Index (FSFI) survey, a questionnaire designed to assess sexual function over the past four weeks. The survey scores six specific domains, including desire, arousal, lubrication, orgasm, satisfaction and pain.

“To our knowledge,” the authors wrote, “this study is the first to use a validated questionnaire to assess the association between female sexual function and aspects of cannabis use including frequency, chemovar, and indication.”

Generally speaking, a higher FSFI score is understood to indicate better sexual function, while a lower score indicates sexual dysfunction. Comparing frequency of cannabis use to each participant’s FSFI score, the researchers determined that more frequent consumption was associated with lower rates of sexual dysfunction.

“For each additional step of cannabis use intensity (ie, times per week),” the report says, “the odds of reporting female sexual dysfunction declined by 21%.”

“We found a dose response relationship between increased frequency of cannabis use and reduced odds of female sexual dysfunction.”

Women who used cannabis more frequently had higher FSFI scores in general, indicating better sexual experiences overall. More frequent consumers also had higher specific FSFI subdomain scores—indicating things like greater arousal and better orgasms—although not all of those differences reached the threshold of statistical significance.

Another weak relationship showed that women who used cannabis frequently reported lower levels of pain related to sex.

“When stratified by frequency of use (≥3 times per week vs <3 times per week), those who used more frequently had overall higher FSFI scores and had higher FSFI subdomain scores except for pain,” the study says.

The research doesn’t shed much light on what marijuana products might work best for sexual stimulation, however.

“Our study did not find an association between cannabis chemovar (eg, THC vs CBD dominant), reason for cannabis use, and female sexual function,” the researchers, who included members of the Stanford Medical Center’s urology department and the medical director of the Victory Rejuvenation Center, wrote. “Neither, the method of consumption nor the type of cannabis consumed impacted sexual function.”

Researchers said a number of mechanisms could explain the overall results, noting that prior studies have postulated that the body’s endocannabinoid system is directly involved in female sexual function. It’s also possible, authors wrote, that cannabis could be improving sex by reducing anxiety.

“As many patients use cannabis to reduce anxiety,” the report says, “it is possible that a reduction in anxiety associated with a sexual encounter could improve experiences and lead to improved satisfaction, orgasm, and desire. Similarly, THC can alter the perception of time which may prolong the feelings of sexual pleasure. Finally, CB1, a cannabinoid receptor, has been found in serotonergic neurons that secretes the neurotransmitter serotonin, which plays a role in female sexual function thus activation of CB1 may lead to increased sexual function.”

As the study notes, cannabis’s potentially positive effect on women’s sexual function was first noted in research from the 1970s and ’80s, when women in research interviews who used cannabis reported better sexual experiences, including more intimacy and better orgasms. But subsequent research has yielded mixed results. Some studies have found that women’s orgasms were actually inhibited by cannabis use. Authors of the new report said that past studies used interviews rather than a validated questionnaire to conduct research.

“The mechanism underlying these findings requires clarification,” the authors said of their report, “as does whether acute or chronic use of cannabis has an impact on sexual function. Whether the endocannabinoid system represents a viable target of therapy through cannabis for female sexual dysfunction requires future prospective studies though any therapy has to be balanced with the potential negative consequences of cannabis use.”

Regardless of the mechanics at work between marijuana and sex, emerging evidence is overwhelming that there’s some sort of relationship at play. A nationwide survey conducted by an East Carolina University graduate student last year found that “participants perceived that cannabis use increased their sexual functioning and satisfaction.” Marijuana consumers reported “increased desire, orgasm intensity, and masturbation pleasure.” Numerous online surveys have also reported positive associations between marijuana and sex, and one study even found a connection between the passage of marijuana laws and increased sexual activity.

Yet another study, however, cautions that more marijuana doesn’t necessarily mean better sex. A literature review published last year found that cannabis’s impact on libido may depend on dosage, with lower amounts of THC correlating with the highest levels of arousal and satisfaction. Most studies showed that marijuana has a positive effect on women’s sexual function, the study found, but too much THC can actually backfire.

“Several studies have evaluated the effects of marijuana on libido, and it seems that changes in desire may be dose dependent,” the review’s authors wrote. “Studies support that lower doses improve desire but higher doses either lower desire or do not affect desire at all.”
