Some days, I really hate my friends

Okay, so, my not-boyfriend (I won't date him, because at the beginning of our relationship, I wasn't going to get too involved; I didn't want to leave him when I left for college -- didn't work out that way) and I worry about each other constantly.  I worry about his smoking, he worries about my self-injury.  So finally we decided to make a deal (bad idea? probably).  If he'll give up smoking, I'll give up self-injury.  So it's going well; he's not smoking, I'm not hurting myself.  Everything's okay.
He calls me yesterday, and says: "Rachel, I need you to keep your end of our promise. But I really need a cigarette. It's not normal circumstances; it's a lot of stress, and I need this."
So, because he's extremely sweet and respects me enough to call me and tell me this and because I assume this has something to do with our runaway friend, I just tell him it's okay and express my wishes that he feel better soon.
I finally, after a few hours, find out what has him so stressed. He's being charged with marijuana possession. God damn it. I know he smokes, but he's careful about it. I'm so baffled. I don't know what stupid thing he could have done to get caught. He's so freakin' stupid. I love him, and I'm worried as fuck about him -- how will this affect his future in the National Guard, how will it affect his already tense relationship with his family? I'm worried sick about him.
But he is so damn stupid. And I hate that.
