I need to quit smoking weed!!

Shannon

I'm in school, and right now I don't have time to find a job, but next semester I'm gonna lighten the load and hopefully find work then. But I get paranoid thinking about it because I've been smoking weed lately (since late May) and I need to pass drug tests. I've done some research about it, and here's what I'm trying to figure out:

I have a low bmi, a fast metabolism, and I smoke at least once every couple of weeks. I used to do it a couple times a week but it's happened less since I moved away for school. And even then, I sometimes just take shotgun hits. How long do you think it would take for the THC to leave my system?
