Smoking Weed doesn’t just decrease testosterone, it alters the balance of hormones in your body.  Less testosterone means more estrogen….and estrogen is what causes the growth of breast tissue and fat in men.

Although the illegality of marijuana has made studies difficult, the National Institute of Health listed marijuana as one of the causes of Man Boobs.
