Smoking Weed May Cause Infertility Because It Makes Men's Sperm Lazy

I think I should start smoking weed again.

A 2002 study showed no impact at all, and a 2003 study found the reverse effect: marijuana smokers ad "hyperactive sperm". The truth is: not enough studies yet to know the truth.

It's a conspiracy...population control ;) That sperm has a playboy magazine lol

The question is: is it permanent, because sperm is replaced quite often

You can look at it that way, or you can view it as you and your thousands of unborn children getting high together.

There MAY be some bias here... ;)
