Does masterbation or smoking pot after a good work out have any negative affects!

Does masterbation or smoking pot after a good work out have any negative affects?

im 19 years old with a pretty athletic build and i like to hit up the gym at least 3 times a week

i usually lift and right after i like to get really stoned for some reason......is that bad? does it affect my muslce gains or testosterone?

i also masterbate within 1-4 hours after the gym every time ...would that have any affect on my testosterone?

one more..........if you jerk it once a day could that be bad?

thanks for the help

Some of the answers on here are ridiculous. Dope has never been proved to lower sperm count, make you're balls smaller or make you infertile. There's nothing wrong with w**nking everyday. There are health costs to smoking dope that include stuff to do with smoking tobacco. But if you use packed tobacco and not cigarette tobacco the danger is reduced significantly. You use much less tobacco, less frequently and it doesn't have all the chemicals and preservatives in it. Walking outside in a city is just as bad with the pollution. Dope fine for enjoying yourself as long as you don't make a life out of it. Wanking won't make your balls shrink either, I've wanked for over a decade and they're as big as they ever were.
