New Studies Show That Marijuana Enhances And Increases Sex

Recent scientific studies substantiate what marijuana users have claimed all along — that marijuana enhances sexual relations. Currently, almost all research into the effects of the cannabis plant is prohibited by The U.S. government due to its classification as a Schedule I substance. However, 30 states and the District of Columbia have legalized medical marijuana, while nine states have also legalized adult use of recreational marijuana. One significant academic benefit of legalization is it finally allows inroads to research the effects of marijuana, including its impact on sexual intercourse.  

According to a research study in the Journal of Sexual Medicine (JSM), entitled the Association Between Marijuana Use and Sexual Frequency in the United States: A Population-Based Study, the goal of the study was, “To elucidate whether a relation between marijuana use and sexual frequency exists using a nationally representative sample of reproductive-age men and women.” 

Researchers Dr. Andrew J. Sun and Dr. Michael L. Eisenberg, are both affiliated with the Department of Urology, at Stanford University, in California.Dr. Eisenberg is an expert in male sexual and reproductive function. As such, he sees men with various forms of sexual dysfunction. As for medical or lifestyle factors that may influence function, he is often asked about what role, if any that marijuana may play. 


The clinical implications of their study revealed that “Marijuana use is independently associated with increased sexual frequency and does not appear to impair sexual function.” In fact, daily users across all demographic groups reported having 20% more sex than those who have never used cannabis. 
Dr. Eisenberg thinks doing more research in this area is important. Previously, most doctors had generally counseled men that marijuana, like tobacco, is harmful.

"Our current study suggests that may not be the case," says Dr. Eisenberg. 

An additional JSM-published study entitled, The Relationship Between Marijuana Use Prior to Sex and Sexual Function in Women, conducted at Saint Louis University in Missouri claims, “The internet is rife with claims regarding the ability of marijuana to improve the sexual experience; however, scientific data is lacking.” The objective of this study “is to determine if marijuana use before sex affects the sexual experience, by how much, and which domains of sexual function are affected.”

In this survey, researchers polled 133 sexually-active adult women at one particular, academic ObGyn practice, during their annual check-ups. The female patients filled out a lengthy questionnaire regarding marijuana use before sex (hashtag #MUBS).

Thirty-eight women (29%) disclosed consuming cannabis prior to copulation. Of those 38 women, 68 percent reported more pleasurable sex, 16% said it ruined their sexual experience, while the remaining 16% were undecided or unaware.  

Among the enhanced sexuality camp, 72% said it always increased their erotic pleasure, while 24% said it sometimes did. Almost 62% said it enhanced the quality of their orgasms and their libidos in general. Additionally, 16% of MUBS adherents disclosed they purposefully puff pot prior to sex, specifically to relieve any potential pain associated with the act. There were conflicting reports as to whether or not it enhanced vaginal lubrication.

The same research team later widened the scope of their survey to 289 adult MUBS women, with similar results: 65% decided it enhanced their sexual experience, 23% said it did not matter one way or the other, 9% had no significant feedback and 3% said it sabotaged their sexual experience. 

Dr. Monica Grover of Asira Medical is Double Board Certified in Family Medicine and Gynecology, with practices in both Midtown, Manhattan and Westchester, New York. Although she did not participate in either clinical study, she is currently conducting independent research.

“Although some studies have shown results that are equivocal, anecdotally patients have reported positive feedback,” says Dr. Grover.

“Consumption of small quantities [of marijuana] prior to sex may increase libido in female patients, which in turn can release positive endorphins and increase vaginal lubrication.”

Dr. Grover believes this may be due to the short-term anxiolytic of cannabis.  In women. Reduced sexual libido in women usually correlates with any anxiety or stress they are experiencing. So, in the short-term, cannabis has anxiety-reducing effects. However, in the long-term, it can increase anxiety, which may explain the lack of libido in possible habitual users. Dr. Grover is currently working on a study to determine this theory.  

Notable clinical implications among male users reported in the Stanford study were that marijuana consumption increases their sexual frequency – daily users reported 20% more sex than people who have never consumed cannabis.  Cannabis does not impair sexual function nearly as much as alcohol does. Nor are there any contraindications of mixing marijuana with other drugs for sexual performance enhancement such as Viagra or Cialis.  

Additionally, and perhaps most importantly, unlike alcohol, so far there is no direct correlation between marijuana consumption and a significantly increased risk of fatalities.

According to the Centers for Disease Control and Prevention (CDC), an estimated 88,0008 people (approximately 62,000 men and 26,000 women) die from alcohol-related causes annually, making alcohol the third leading preventable cause of death in the United States.  The Journal of the American Medical Association corroborates these findings. The first preventable cause of death in the United States is tobacco use and the second is poor diet and physical inactivity. These findings may help build the case for consuming cannabis to become more sexually active to benefit one's overall health.
