Marijuana and the male orgasm

"Oh yeah, oh yeah... omigod, I'm so close. I wish I had some beer, but I wanna come. Ooo, I want a burrito. Why can't I come?!"

Sound familiar? An Australian study has found that men who smoke marijuana on a regular basis are four times more likely to have difficulty reaching orgasm than men who don't smoke. The same study also discovered that potheads experience premature ejaculation at three times the rate of non-smokers. What gives?
