It does not, at least not by much. Long term heavy users of Marijuana may have a slightly reduced sperm count, but it does not make them sterile or impotent, and it certainly doesn't act as Birth Control!
It can if you smoke it a lot for many years, yes.
No It Does not it makes you have delayed response
It has been known to lower sperm count temporarily. It is NOT a method of birth control, however.
yes weed will decrease sperm count! if you smoke it long enough, later on down the road you could even become sterile
No. but then again make sure you might just soak everybody in the sticky stuff.
I'm not sure it "damages sperm" per se, but it can contribute to infertility and low testosterone levels.
No, but smoking weed can kill brain cells.
Mostly in the grammar area.
smoking weed does not affect your period, smoking grass might however
Smoking weed has no bearing on how "strong" a mans sperm is.
Smoking weed does not make you skip a period. The THC chemical has no affect on the reproductive system.
Of course not! Weed doesn't lower the amount of testosterone in your body. It will have no affect whatsoever.
No, it's perfectly healthy
It will destroy your mind.
Smoking weed, smoking weed, and smoking weed
There is no stats to support that smoking weed will stop you from conceiving. It's not a form of contraception. It's rumored to effect your sperm count, but this will still allow contraception.
No, smoking weed will not do anything to affect the fast. Although it might make you hungry and make it hard to stick to the fast.
No way, man. Smoking weed does not alter your DNA, no matter how much you think you smoke.
yes
Yes, it affects the entire system and your heart.
