Here’s What the Science Says About Cannabis & Sex

Cannabis is used for a wide variety of reasons. Some people want to reduce pain or sleep better; others just want to chill or have a bit of fun. But what happens when you bring the plant into the bedroom? Does weed make you horny?

Little research has been conducted on cannabis and sex, but a few studies do exist. Some studies show that cannabis may improve sexual function, particularly in women. 

Anecdotally, there’s far more out there. Many consumers report that sex on weed feels more intense or pleasurable, and a few maintain that, yes, the pot puts them in the mood. But that may not always be the case.

Weed likely won’t turn you into a sex-crazed maniac, ala Reefer Madness, but the plant can impact your sex drive, for better or for worse. Much like everything in life, there’s no one-size-fits-all when it comes to cannabis and sex: here’s what we know so far.

How cannabis works in the body (the full body)

Cannabis is processed through the endocannabinoid system (ECS). The ECS comprises thousands of cannabinoid receptors, including CB1 and CB2. These receptors are found throughout the body—including in the sexual organs of both men and women.

Research on direct correlations between the ECS and sexual function remains limited, but several hypotheses have been proposed. The primary function of the endocannabinoid system is regulation, ensuring that other systems function in harmony. Thus, much of the research focuses on how the ECS affects the reproductive and nervous systems.

For example, the ECS is believed to modulate hormones that impact the menstrual cycle in women and vasodilation (erectile function) in men. Additionally, one study showed the ECS may directly affect sexual function due to its ability to signal neurotransmitters that play a role in the release of dopamine and serotonin.  

Knowing, it’s safe to say cannabinoids do impact the sexual experience. But does weed make you hornier? 

Can weed make you horny?

The short answer is: maybe. The issue with both cannabis and sex is that they’re both deeply personal, and individual results vary. However, signals do point to “yes.”

First, it’s important to remember that cannabis tends to help people lower their inhibitions. If smoking weed or eating a gummy helps you relax and feel less nervous when around the object of your desire, it may feel easier to get (and stay) in the mood. But what does the research say?

Several studies examining self-reported data of cannabis consumers suggest the plant could benefit your sex life. A study published in 2023 surveyed over 800 cannabis consumers and found that more than 70 percent of participants reported increased sexual desire and orgasm intensity. Many also associated cannabis with improved sexual satisfaction. The authors noted that cannabis could be a viable treatment for women experiencing sexual dysfunction.

This is not the only time researchers suggest that cannabis could help women in the bedroom. A 2024 study showed the plant could lead to better and more frequent orgasms for women who struggle to climax during partnered sex. In that survey, nearly 73 percent of respondents reported that cannabis use before sexual activity increased orgasm frequency, 67 percent stated that it improved orgasm satisfaction, and 71 percent indicated that cannabis use made orgasm easier. 

A 2025 analysis of available literature also pointed to cannabis being a promising option for women struggling with female orgasmic disorder/difficulty (FOD). The authors concluded that FOD should be a qualifying condition for medical marijuana in states with regulated programs. However, only a few have approved the condition so far.

Another study found that cannabis users may have more sex overall. The findings, published in the Journal of Sexual Medicine, revealed that both men and women who consume weed reported a higher number of sexual encounters versus non-users. The research authors said marijuana doesn’t seem to impair sexual function. But that’s not the end of the story.

Cannabis and sexual dysfunction

While cannabis has been shown to increase sexual arousal and orgasms among women, the jury is still out for male consumers. In fact, some evidence suggests a high frequency of cannabis use could be problematic in more intimate settings.

As noted above, the ECS modulates vasodilation (the widening of blood vessels). An erection is directly dependent on vasodilation, and if the system is overloaded, it could lead to issues. Research is conflicting, but some studies suggest that chronic THC consumption could result in erectile dysfunction (ED).

A 2019 meta-analysis doesn’t paint a pretty picture. Study authors found that cannabis consumers were twice as likely to have erectile dysfunction as non-consumers. However, they found no direct correlation between the plant and ED.

FAQ

Still wondering how marijuana and sex work together? Here are some answers to common questions.

Is weed an aphrodisiac? 

Cannabis may help enhance sexual experiences by lowering inhibitions and modulating function. While it may not be a natural aphrodisiac, its effects may help put you in the mood if the time is right.

What makes you hornier, weed or alcohol?

This depends on the individual, but both substances have advantages and disadvantages. Alcohol may make you more confident, but it is more likely to lead to sexual dysfunction. Cannabis can heighten sensations and make orgasm easier, but it may lead to anxiety or ED.

Does indica or sativa make you hornier?

There’s no clear winner, but sativas tend to be more energizing while indicas tend to be sedative. If indica strains put you to sleep, a sativa or hybrid like Super High Life may be the answer. If sativas evoke paranoia, a chill indica like All Gas OG could be better.

Can weed cause hypersexuality?

Cannabis consumers statistically have more sex, but it may not cause hypersexuality. One study suggested a possible association, but the limitations preclude establishing a causal link.

Why is sex so good when high?

Cannabis may heighten physical and emotional sensations. This could lead to people feeling as though sex “feels better” after they’ve consumed cannabis. 

Cannabis and sex: final thoughts

If you’re one of the people who wonder, “Why does weed make me horny,” there may not be one clear answer. The effects of cannabis can vary widely from person to person, as does sexual response. But based on the science and user reports, the plant is definitely apt to get you in the mood. 

Whether it’s easing your inhibitions or releasing dopamine in the brain, cannabis affects the body in multiple ways. And while some men may have difficulties in the bedroom after smoking, it’s unclear if it’s the weed causing the issues. So why not smoke with your sexual partner and see what happens?
