Yep, long story short: 2 years ago I started smoking weed regularly, not even much, I smoke 1/3 of a joint every 2 days. Anyways, few months after smoking marijuana regularly I stared feeling my libido going down a lot, also I get tired at nights and lost a lot of interest on the other sex. So I go to see the urologist and I'm perfectly fine EXCEPT that I have low testosterone, and the doctor says Marijuana is definitely a contributing factor. Am I gonna stop smoking? No, I'm just gonna get a testosterone shot every 3 months, but they ain't cheap so I'm just giving you the heads up.
