In order to evaluate the relationship between cannabis (marijuana) use and sexual frequency, this study analyzed data from the National Survey of Family Growth gathered between 2002 and 2015.
The results of 28,176 women and 22,943 men who all averaged just under 30 years of age were evaluated for the four weeks just prior to the survey administration. Both female and male cannabis users had a significantly higher frequency of sex when compared to those who never used. In fact the authors even stated that the higher the frequency of use, the greater the frequency of sex. There was no indication of sexual impairment from using marijuana.
