<human>: I've just fallen head over heels for this guy, we get along super well but this weekend we were hanging out with his buddies and they pulled out some weed and started smoking. He and I were talking and he says to me, "i know we haven't talked about this but I occasionally smoke cannabis. Is it ok if I do some tonight?" I was a little flabberghasted but said yea, sure, dont worry about me. 

The problem I keep coming back to is that I am in a doctoral program, working toward a career I've been dreaming of my whole life. Its not so much the drug I'm concerned about because he only uses 2-3x a month, and if you're gonna be on something, at least its not the really bad stuff. But its still illegal and if he gets caught and I'm with him, that could seriously jeopardize my career and his. I'm also worried about how committed he is to his career. He is so smart and is also working to get into a doctoral program. We both want to be in the healthcare field and the penalty for testing positive in that field is extreme. How devoted are you if you're willing to let a fun thing with friends potentially get in the way?

My friends all say to run (well, the two I've told; one got so mad she started shaking). I've only known him a month but I feel like it's been longer than that. I've talked to him and he says I'm more important than weed. Do I ask him to stop using and trust he wont (even though he does it with his close friends). Or do I just take the bullet and break up with him?

Can you summarize the given text in a few sentences?
<bot>: I've only known him a month, we get along really well, I've really fallen for him, but this could really fuck with my career and his if he gets caught. What do I do???
