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.Sore tongue smoking weed?
