Regular marijuana usage robs men of sexual highs - New Scientist

Stoners may be trading sexual highs for the chemical kind. Males who smoke marijuana daily are four times more likely to have trouble reaching orgasm than men who don't inhale, finds a new study of 8,656 Aussies...

Even though many male smokers experienced sexual problems, they reported more partners than non-smokers. Marijuana users were twice as likely to have had two or more sex partners in the previous year than men who didn't smoke pot.

Pitts' team found an even stronger trend for increased sexual activity among female smokers, who were also seven times more likely to have been diagnosed with a sexually transmitted infection in the last year than non-smokers. However, female smokers had no more problems in the bedroom than abstainers, Pitts' team found.

It's interesting to read the comments that follow the story, many of which are somewhat amusing:

Perhaps stoners are just twats and that is why these problems occur. Yeah - from those I've known that hypothesis fits the data pretty well. I never met a stoner who wasn't a total wanker. Someone needs to do the necessary research to confirm it.

And:

Here are my (unscientific) theories

1) more partners

the stoners just can't be bothered to put up with each other's crap all the time and thus split more readily

2)trouble reaching orgasm

the stoner just can't stop thinking about that new cushion recently purchased, how do they make them that fluffy!?
