No, simply supersticion
Weed does not protect anyone from pregnancy but it can make the guy fumble with the condom. If the condom is used correctly you have zero chance of pregnancy.
Get over him and find someone at least halfway decent. A guy who's already smoking weed in middle school is nothing but trouble.
Same as if he wasn't smoking.
Most definitely. It's said to affect sperm motility but I don't believe by much. Depends on how much the guy smokes and the overall health of the man and woman. I've had friends who were major stoners get girls pregnant but at the same time I've had other friends who have tried for a baby and it took them longer than it probably should have. If you're worried about becoming pregnant, don't use weed as a form of birth control. If you're trying for a baby, decide if you want that baby badly enough to give up smoking.
There's really not much you can do. I would tell you to stop liking him, but I know how hard it is to stop liking a guy. Sometimes, though, the only way to stop liking a guy is to get rejected by him. I know how odd that sounds, but it'll help you get over him. Besides, the fact that he drinks all the time and smokes weed might be a segue into what kind of guy he is. I'm not saying that all guys who smoke weed and drink are mean and selfish and don't care about you, but some guys who do are. Unless you know his personality, I'd say that you're best not taking the risk.
The drug marijuana is said to kill brain cells. This does not mean that a person becomes dumb, it just means that they do not have as many brain cells available to them.
No, pot is a great way to prevent pregnancy.
What is he smoking? If they are cigarettes then no. I have had 4 boys all healthy and my husband smokes so no, cigarettes have no effect to my knowledge
Give him lots of cigs.
Kristen Stewert smokes, Niki Read smokes, the guy who play Carlisle smokes, but I'm unsure about all the other cast, sorry.
you will die! i'm not joking with you, because my friend's grandma was kissed a man that smokes, then after 1 year she died!
