Professor,

The parts I added to the Wikipedia page is everything between the //START and //END sections below. I really wanted to do something cross culturally, but I had no luck finding good sources for it. Instead, I provided additional research and expanded on some items. Hopefully everything sticks. Two people have gone in and removed parts of the page recently, but thankfully it was not anything I edited. Thank you for a great semester!

//START OF MY SECTION

Marijuana use is commonly thought to enhance sexual pleasure. There is limited scientific research on the effects of marijuana and sex, however, and it is not well understood. The lack of research is in part due to U.S. drug policies centered on prohibition. In addition, the effects are difficult to study because sexual arousal and functioning are in themselves extremely complex and differ among individuals. Moreover, marijuana affects people differently. As a result, it is challenging to study. Men and women report greater sexual pleasure after having consumed marijuana, but there is no direct scientific evidence of the effects on the physiological components of the sexual response cycle when using the drug.

Research
Research of the effects of marijuana and sex on humans is so far limited to self-report studies. This type of study has disadvantages because it requires people to accurately remember how much they consumed and its effects, while researchers have no way to verify responses. In these studies, the majority of men and women who consumed marijuana prior to sex reported they experienced greater pleasure than without it. Researchers believe this reported increase in sexual pleasure with marijuana is likely a result of the drug’s effects on the senses. In particular, it commonly makes users feel more relaxed.

There is some research that suggests the amount of marijuana consumed affects the experience. In one study, 59% of users thought that sexual pleasure was enhanced after smoking one joint. Less than half (39%), however, thought that consuming more than one joint provided further enhancement. In addition, large doses of marijuana have been used as a sexual depressant in India.

It is not clear if marijuana consumption affects the quality of orgasms. Just over half of male consumers and a lower percentage of female consumers reported that it enhanced their orgasms. In a small study published in 1979 of 84 graduate students, the majority of which were men, those who reported being “experienced smokers” believed that it increased the intensity of an orgasm and should be considered an aphrodisiac. A number of more recent studies do suggest orgasms are improved with marijuana use, however.

Studies on marijuana consumption’s effects on sex have shown little other significant physical improvements. Masters and Johnson completed a five year long study in 1979, with a sample size of 800 men and 500 women whose ages ranged between 18 and 30 years old. In this study, men reported no improvements in maintaining erections or an increase of penile firmness. Women reported no increase of vaginal lubrication.

A more recent study in 2017 in the Journal of Sexual Medicine, looked at data from the large nationally representative National Survey of Family Growth and included more than 28,000 women and nearly 23,000 men. It reviewed survey responses on how frequently they had consumed marijuana and had sex in the four weeks prior to the survey. It found that women who consumed cannabis daily had an average of 7.1 sexual encounters in the previous four weeks compared to 6 for those who never consumed it. Men who consumed marijuana daily reported having sex 6.9 times on average compared to 5.6 times in those men who never consumed it.

There has also been some evidence of negative effects on marijuana use on sex. Some studies show a correlation between chronic marijuana use and reduced testosterone levels in men. Furthermore, it has been found that heavy use of marijuana decreases the sperm count of healthy men. This reduction in sperm count can be reversed. Chronic use of marijuana is also linked to a decrease in sexual performance, while increasing sexual arousal.

One study published by Sexual Medicine in 2019 suggests cannabis consumption before sex could improve orgasms for women. Not only directly before sex, but one study by the US National Library of Medicine has shown that "After adjusting for race and age, women with frequent marijuana use, regardless of use before sex or not, had 2.10 times higher odds of reporting satisfactory orgasms than those with infrequent marijuana use.”

Products
There are a variety of cannabis-infused sex products, such as lubricants and massage oils containing CBD and THC.
