New Study Says Marijuana Use Does Not Affect Fertility

One of the many rumors people have heard about marijuana use is that it decreases the ability for a person to conceive a child. But a new study finds that's a load of baloney.

An article published in the Journal of Epidemiology and Community Health earlier this year found that claims about cannabis use decreasing fertility were not true. More than 4,000 women and 1,000 men were enrolled in the study to determine the effects of the drug on fertility. 12 percent of the women in the study and 14 percent of the men were marijuana users.

The researchers found that marijuana users did not have a difference in fertility compared to non-users, implying that there's no connection between the two. Interestingly enough, men who consumed cannabis more than once a week were actually 24 percent more likely to conceive a child than those that did not. 

The study isn't perfect, however. The data used was mostly based off Internet questionnaires. This was not a lab study using control groups. But considering there were over 5,000 participants in the study, it's safe to assume that if marijuana did decrease fertility rates, they would've at least seen some evidence of it.

So if you're trying to conceive, don't worry about toking up. If anything, it may put you more in the mood.

Cannabis legalization does not lead to increased use by young people, according to a federally funded study. In fact, legal states have seen underage consumption decrease since repealing prohibition. The National Institute on Drug Abuse (NIDA) has released the latest iteration of the regular Monitoring the Future survey, evaluating the drug habits of American eighth, tenth and twelfth graders.
