It is just a simple question not to do with a illness but still important to me. I was talking to a friend the other day and she said that if you made out with someone who smokes marijuana that it will also transfer into your system. I just wanted to know if this was a myth or a fact. Now I just want to make it clear I don’t make out with random people but I was curious because it is a good thing to know and could possibly help to stop others I know from dating certain people.

Well, that’s a question you don’t hear every day. I guess you could theoretically get trace amounts of the drug into your system this way, meaning that the amount is so small that it is practically negligible. However, you are likely to get significant amounts of marihuana into your system if you stay in a room where it’s being smoked, i.e. passive smoking.
