"I don't know why your boyfriend smokes pot. I was a big pothead in high school and college and I started simply because it was fun."

"It felt super good and it made me happy. But I kept doing it because it made me complacent. I never got angry or frustrated and I never cared about anything too much to let it get me bent out of shape. (Except weed. I got really angry when I couldn't smoke weed.) I think some people do specifically do it because it takes the stress of caring away. It makes things easy. Maybe your boyfriend feels stressed out. I also had some depression at some point in my potheadedness (I don't remember where), and smoking pot was an activity that felt good and passed the time. As a depressed person, I couldn't pour myself into hobbies, but I could indulge in physical pleasures like pot. Since he's smoking when he wakes up, to me that seems more of an approach to manage stress. I'd add, some people do just enjoy smoking pot, but the everyday part and the waking-and-baking makes it seem like a crutch. Whatever it is, I don't think it's something you can change and if you try, will probably just result in fights and be unpleasant for you. You should decide whether you're OK with him dealing with stress or passing his time this way or not. And if you're not, find a new guy."

An answer is attempted, to a question asked at Metafilter.

My question: If "medical marijuana" is a legitimate concept and you use marijuana every day, should we assume (or worry) that you have a medical problem that warrants more scientific medical treatment or (if it's a psychological problem) more intelligent and direct personal engagement? And: Isn't marijuana going to make it difficult for you to give a straight answer to that question?
