In a study published in the medical journal Human Reproduction, researchers analyzed many different lifestyle factors that could possibly have an impact on male infertility. The study was the largest of its kind, examining how habits such as smoking and drinking alcohol affected men’s sperm size and shape – also known as sperm morphology.
According to the researchers, marijuana use was the only habit they studied to be strongly associated with abnormal sperm morphology.

i didn't read the link but I would assume that eating genetically modified foods would eventually play a role. Also eating foods covered with pesticides and not washed correctly etc etc. Also, we eat way more salt and sugar than is good for us and I'm sure over generations that HAS to impact us somehow.

No no. Now there is mutation for sure but we still evolve but not as we used to. Now we are forcing the changes instead of letting nature take it's course.

I think it will be a good experiment. That's the only way we'll know what happens to people when the populations of 2 entire states are constantly zoned out on a particular drug. An actual long term research experiment on such a large group of people would be deemed unethical.

That, and the greatest marker of fertility (by a huge margin) is testicle size.

Here's an older story from 2003 and not Fox News. Apparently, men's sperm go all hyperactive on THC, then burn out their motors well before they get to home base. But it gets better. Women who smoke have the THC show up in their vaginal fluids. So once the sperm gets "deposited", they come into contact with the already present THC and never make it to their destination for the same reason.

And here I thought my massive nuts was a bad thing...
Kinda counter intuitive. You'd think a stoner's sperm would be slower and more lazy. I'd have guessed a tweaker's sperm to much faster and quicker to burn out. Go figure.
