Lovely Drug testing

Well, again here is another thread about durg testing and the big M. I haven't smoked since this past Saturday but I had 2 small bong hits but I didn't really get high. I sent out applications and they give drug tests. The thing is people tell me it takes up to 3 weeks to get out of your system but I basiclly smoke when weed is offerend, which is once a weekend or sometimes never.
I don't see how it will take up to 3 weeks since I am 5'7" and 102 lbs lol. So what do you people think? I drink about 4 glasses of liquid a day and have barely any body fat.
I'm curious as of how long it will take to get out.

Depends how much you smoke when you do decide to smoke again. If you burn a couple joints or more your probably gonna fail for at least a whole week, probably more. If you smoke a couple one hitter bowls or one or two regualar bowls you will probably be good by the later part of the week. Thats assuming you don't smoke a lot now, it took me 2 months to get entirely cleaned out when I had a job with drug testing because I was smoking at least a bowl or two and usually more every day.

Well seeing as your freaking little lol it shouldnt be bad. Also since you dont go out smoking blunt after blunt it should be little time.

Excercise and water.
