<human>: I'll start by saying that this is not a debate about what is morally wrong or right. I am pro-legalization of marijuana, do not believe people deserve punitive sentences for possessing or using.

So as the title states, my boyfriend wants to smoke weed and it's a deal breaker for me. We've been together for 6 years. He has used it in the past but quit when I asked him to. About a month ago, a co-worker asked to have "friend time" and he more or less asked my permission and said that he would really like to use it because he had been having a shitty week at work. I hesitantly agreed. It wasn't bad, but I really would prefer if he didn't use or spend money on it.

This isn't something specifically against marijuana. It would be a deal breaker if my partner smoked cigarettes. For me, it's about staying as healthy as possible. I've never smoked anything, I rarely drink. I'm in grad school, in a program that promotes overall health. I plan to apply to health psychology program and they really look down on the students that smoke cigarettes. Health is something that really value in myself and my partner.

I've told him, if it's something that is really important for him, I'm willing to break up. He refuses to break up but continues to smoke. I know it's unfair of me to ask him to stop smoking, and so I haven't. But I think it's unfair that he gets what he wants, smoking weed and being in a relationship with me, while I'm unhappy because I'm sure that there are people out there that don't smoke. And if that's what I want, I think that I have the right to attempt to find someone who doesn't smoke weed or cigarettes and values health as much as I do.
