Cannabis and Libido: How Weed Affects Your Sex Drive

Occasional Use: What Weed Can Do in the Moment

At low doses and in occasional use, cannabis can make sex feel better for some people. The relaxation takes the edge off performance anxiety, touch can feel more intense, and time seems to slow down.

That is not just forum talk. In a Canadian survey of 216 people who had used cannabis with sex, about 6 in 10 said it raised their desire and about 7 in 10 said they could relax more and felt touch more strongly. Some also said it made them sleepy and less focused.

A US clinic survey of 373 women found that those who used weed before sex were about twice as likely to report satisfying orgasms. And a large US population study found that people who use cannabis report having sex somewhat more often than people who never use.

This is the side people quote when they call weed an aphrodisiac. It exists, but these studies are surveys. They show a link, not that weed caused it, and they say little about what years of daily use do.

Daily and Heavy Use: The Flip Side

Daily cannabis use has a different effect on sex. Several things are at work, and the evidence for each one is not equally strong.

Testosterone. You will often read that weed lowers testosterone and that this kills your sex drive. The larger studies do not back that up.

A Danish study of 1,215 young men found slightly higher testosterone in men who smoked weed. A US study of 1,577 men found no difference between men who had ever used and men who never had. The same Danish study did find something else: men who smoked more than once a week had about 28 percent lower sperm counts.

Dopamine system blunting. Brain scans of heavy users show a weaker dopamine response in the reward system. In one study, the weaker that response was, the more irritability, low mood and craving people reported.

Sex is one of the strongest natural rewards. When the reward system answers more quietly, it makes sense that the pull toward sex can feel weaker too, although no study has measured that link directly. Understanding the mechanism: How Daily Cannabis Use Changes the Brain.

Emotional and relational disconnection. Regular cannabis use is often linked to being less emotionally present. Sex is not purely physical, and the emotional side matters.

When cannabis keeps producing a version of you that is less engaged and less present, it affects the closeness of sex, not just the physical part.

Erection and orgasm problems. A review of five small studies found higher rates of erectile dysfunction in men who smoke cannabis. The studies differed a lot from each other, so the authors called for better research before drawing firm conclusions.

An Australian survey of more than 8,600 people found that men who used daily were more likely to say they could not reach orgasm, or reached it too fast or too slowly. In women, that survey found no link between how often they used and sexual problems.

What the studies on weed and sex found

Study	Who	Finding
Sun and Eisenberg 2017	About 51,000 US adults	People who used reported a bit more sex than never users
Wiebe and Just 2019	216 people who used with sex	Most said more desire and stronger touch, some said sleepy and less focused
Smith et al. 2010	About 8,600 Australians	Daily-using men reported more orgasm problems
Pizzol et al. 2019	Five studies, about 3,400 men	Erection problems more common in users, weak evidence
Gundersen 2015, Thistle 2017	About 2,800 men	Testosterone not lower in users

So the honest picture is mixed. Weed can make sex feel better in the moment for some people, and daily use can still cost men some control over erection and orgasm. Both can be true for the same person at different stages.

What Happens When You Quit

There are hardly any studies that follow sex drive after people stop. What we do know: the dopamine and cannabinoid systems that daily use dials down tend to recover with time off.

Many people who quit after years of daily use say their desire came back stronger than they expected, sometimes to a level they had not felt since before they started smoking every day. For a lot of them, it is one of the more pleasant surprises of quitting.

The first weeks of withdrawal can bring poor sleep, irritability and a flat mood, so do not judge your sex drive by week one. More presence and real desire usually come later. For a full picture of the recovery timeline: Quitting Weed Benefits Timeline.

Individual Variation Is Significant

Not everyone experiences the same effects. Some people use cannabis heavily for years with little change in their sex life. For others, the drop is clear and the change after quitting is striking.

If you have noticed a real change in your sex drive since you started using cannabis regularly, count it as part of what the habit costs you. If erection or orgasm problems stay after you stop, talk to a doctor, because they can have other causes too.
