Well this guy smokes a lot , like a joint or two a day... and I just started making out with him lately , so will this affect me in any way
It wouldn't really affect you unless you were inhaling smoke or ingested weed. There are some people who eat weed and get high, yes. Kissing a guy who normally gets high is not going to get you high at all or affect you in any way.
Will being with a guy who smokes everyday (signifying a problem btw) affect you in any way. Yes. It will definitely affect you. However, no, it wont affect you physically.
