http://dailydigestnews.com/2014/06/weed-but-not-booze-can-affect-fertility-in-men/ another b.s. study. http://www.sheffield.ac.uk/news/nr/sperm-size-affected-by-cannabis-use-1.377749 let me re-interpret the data.. a little: - some men who go to fertility clinic smoke pot. - a relatively small percentage of men in a fertility clinic have abnormal sperm size. what sort of accurate representation can be made if you measure data from people who are visiting a clinic because of a potential fertility problem? sense no make.
Heard these same scare tactics in the late 70's. The sperm are fine, they are just a little stoned and are enjoying the trip!
