To determine what the problem is, they'll go through a laundry list of regular activities.
People have often claimed that marijuana usage is linked to impotency.
There isn't a lot of research on the topic.
Marijuana is legal for medical or recreational adult use in 29 states and the District of Columbia, said spokesman Morgan Fox of the Marijuana Policy Project.
What he found surprised him.
Study subjects were asked ow many times they had heterosexual intercourse in the past four weeks and how frequently they smoked marijuana in the previous year.
The findings can be found published online in the Journal of Sexual Medicine.
BCCI to take 'appropriate measures' after Pune curator sacking
New Zealand were just out 230-9 after a pitch-tampering controversy threatened to disrupt the second one-day worldwide in Pune on Wednesday.
The researchers used data from the National Survey of Family Growth, which queries men and women about marriage, pregnancy, infertility, and sexual health.
Nonsmoking women reported knocking boots an average of six times during the previous four weeks, while daily tokers said they did it just more than seven times. In an odd Catch-22, Shamloul says that recent research suggests cannabis might actually make it harder for a man's penis to become erect, even if weed might turn people on. Women who didn't use marijuana in the previous 12 months reported having heterosexual intercourse an average of 6.0 times in the preceding four weeks, while women who smoked marijuana daily had sex with men 7.1 times in the past four weeks. In other words, using marijuana more frequently doesn't directly cause more sexual activity. "This would have helped control for any distorted perceptions of sex related to marijuana use".
"It can have a different impact on different people", said Joseph Palamar, an associate professor in the Department of Population Health at New York University, who is not connected with the current study told CNN.
He thought it was a "cool epidemiological paper" that "did the best it could with the data", but it did have limitations.
On the other hand, experiments on both animals and humans have shown that the drug also stimulates activity in the parts of the brain involved in sex and sexual arousal. Too much cannabis can lead to paranoia, anxiety and excessive mental chatter. He added he'd like to see a study that could show more of a direct effect on frequency.
"While the results are very interesting, it's premature to suggest that marijuana may have a medicinal use in the treatment of sexual disorders such as erectile dysfunction, premature ejaculation or orgasmic disorder", Vira said.
Calling into question stereotypes about cannabis use and sexual desire and performance, a new study finds that frequent marijuana users have more sex than nonusers - about 20 percent more sex, in fact.
It's an issue because more and more people report using marijuana as states legalize it.
