Here’s how marijuana use affects sex drive
Researchers found a “dose-dependent relationship” between marijuana use and intercourse.
- Do you and your lover sometimes have a glass of wine or two to help set the mood? Alcohol, while it can soften inhibitions, may also cause trouble when it comes time to perform, especially for men.
- Some turn to cannabis as an alternative.
- Unfortunately, research on how marijuana affects sexual performance is conflicting.
Some studies say it inhibits capability while other say it enhances it. A new, large-scale study finds that marijuana use increases the sex drive and probably doesn't inhibit performance. Scientists at the Stanford University School of Medicine conducted the study and published their results in the Journal of Sexual Medicine.
Cannabis has been thought an aphrodisiac in the folk medicine traditions of many cultures throughout history. Today, a small but growing segment in the West are using it to help enhance their sex lives. One California woman is even selling “Sexxpot," a low-THC variety (the psychoactive component) said to increase female sexual desire and pleasure.

As for men, though online forums and advice columns praise it as a “natural Viagra," some studies have found that cannabis may actually inhibit performance. Previous work has also suggested that chronic use inhibits sex drive. A 2009 study found that everyday use may make it difficult for some men to achieve orgasm. While a 2011 review concluded that chronic use may lead to a higher risk of erectile dysfunction.
This new study however seems to undermine the case for inhibited performance or libido. Stanford researchers analyzed the responses of 50,000 Americans who took part in the CDC's National Survey of Family Growth. They looked at the years between 2002 and 2015. Each participant was between ages 25 and 45. The average age for both men and women was actually 29.5.
Respondents indicated how often they smoke marijuana, either monthly, weekly, or daily, and how many times they had sex in the last 12 months. Assistant professor of urology Michael Eisenberg, MD, was the senior author. “Marijuana use is very common," he said. “But its large-scale use and association with sexual frequency hasn't been studied much in a scientific way."

“What we found," Eisenberg said “was compared to never-users, those who reported daily use had about 20 percent more sex. So over the course of a year, they're having sex maybe 20 more times." Women who didn't smoke pot had sex an average of 6 times per month. While those who were daily users did it 7.1 times per month. With men, non-potheads had sex 5.6 times per month, while daily users did it 6.9 times per month.
According to Eisenberg, “The overall trend we saw applied to people of both sexes and all races, ages, education levels, income groups and religions, every health status, whether they were married or single and whether or not they had kids." Researchers called it a “dose-dependent relationship."
The more people used marijuana, the more sex they had. These findings also alleviate some of the anxiety surrounding performance inhibition. “Frequent marijuana use doesn't seem to impair sexual motivation or performance," Eisenberg said. “If anything, it's associated with increased coital frequency."

There are of course, some caveats. For couples who are trying to have children, several studies have found that chronic pot use can cause a man's sperm count to plummet. Toking just once a week can sink the number of swimmers a man has by about a third. There's also still a lingering fear among some experts that chronic use can lead to ED.
It's important to note that the study didn't prove a cause-and-effect relationship, merely a strong correlation. Smoking marijuana doesn't automatically mean you'll be having more sex. There may be another factor or factors that are influencing the two. For instance, those drawn to marijuana may also be less inhibited or thrill-seekers, who are naturally more inclined to seek out sexual encounters.
Eisenberg says he thinks marijuana's positive correlation with intercourse isn't just a tendency among the less-inhibited. He points out that the number of sexual encounters rose steadily with increased use. If these findings prove correct, certain synthesized cannabinoids or elements in marijuana, may someday be used as a medical treatment, to foster libidinous feelings in those who find that their desire has waned. Eisenberg cautions, "We don't want people to smoke to improve sexual function." But he admits, “it probably doesn't hurt things."

Africa is home to the rivers with the world's second- and third-largest catchment areas: the Congo (in blue), with a basin of 1.44 million square miles (3.73 million km2), and the Nile (in red), with basin area of 1.26 million square miles (3.25 million km2). The Nile is the longest river in Africa, though (4,130 miles; 6,650 km), followed by the Congo: 2,900 miles (4,700 km). The Congo River's alternative name, Zaire, comes from the Kikongo nzadi o nzere ('river swallowing rivers'). Image source: Grasshopper Geography

The Volga (in yellow) is the river with the biggest catchment area in Europe (just under 545,000 square miles; 1.41 million km2). It flows exclusively through Russia, and the catchment area is entirely within Russia as well. Europe's number two is the Danube (in orange), which flows through 10 countries — more than any other river in the world. Its drainage basin (just over 307,000 square miles; almost 796,000 km2) includes nine more countries. Image: Grasshopper Geography

The hydrographic map of Germany is dominated by just four major drainage systems: the Danube (in orange) in the south, the Rhine (in blue) in the west, the Elbe (in purple) in the east and the Weser (in green) between the latter two. In Antiquity, the Rhine was the border between the Roman Empire and the Germans. Rome once attempted to shift the border to the Elbe, which would have radically altered the course of history, but it suffered a massive defeat in 9 CE at the Teutoburger Wald (roughly between both rivers).

Both Ireland and Great Britain are islands, as a result of which neither boasts a continental-class river. Twenty of the 30 longest British rivers are less than 100 miles (160 km) long. The longest river in Britain is the Severn (220 miles, 354 km), its catchment area shown in blue in the southwest. Ireland's longest river is the Shannon (224 miles, 360 km). Even combined they're not as long as France's Seine (483 miles, 777 km). Image: Grasshopper Geography

Spread-eagled across the central part of the United States, the Mississippi's drainage basin covers all or parts of 32 U.S. states (and two Canadian provinces). The easternmost point of Ol' Man River's catchment area is really far east: Cobb Hill in northern Pennsylvania. Here rises the Allegheny, tributary of the Ohio, which in turn flows into the Mississippi at Cairo, Illinois. Image: Grasshopper Geography

Even leaving out the Mississippi, there's enough going on in the rest of North America to keep the eye occupied. Here's a drainage map of Washington State. The big fish in this much smaller pond is the Columbia River (drainage area in blue), the largest river in the Pacific Northwest. Only in the western third of the state is there a colourful counterpoint, in the multitude of smaller river basins that are draining into the Pacific or into Puget Sound. Image: Grasshopper Geography

At 1,558 miles (2,508 km), the Murray is Australia's longest river. It is often considered in conjunction with the Darling (915 miles, 1,472 km), the country's third-longest river, which flows into the Murray. The Murray-Darling basin (in blue, in the southeast) covers just under 410,000 square miles (1.06 million km2), or 14 percent of Australia's total territory. Don't let that spidery network of river courses in the interior fool you: Australia is the world's driest inhabited continent (Antarctica, bizarrely, is drier). Image: Grasshopper Geography

Four of the world's largest drainage basins are in Russia: the Ob, Yenisei and Lena (origin of Vladimir I. Ulyanov's nom de guerre, Lenin) entirely and the Amur, shared with China. The Volga may be Europe's longest river, but 84 percent or Russia's surface water is east of the Urals, in Siberia. The sparsely-populated region is traversed by 40 rivers longer than 1,000 km. Combined, the Ob, Yenisey and Lena rivers cover a drainage area of about 8 million km2, discharging nearly 50,000 m3 of water per second in the Arctic. Image: Grasshopper Geography
