Invisible Man

long story short i just got an intern job that randomly tests. i take this as a good chance to cut down on smoking due to financial issues. so i've created a plan. the only problem is i dont know how effective this would be.... so maybe some of you can help me out.. first of all, i've been clean since july 7th, i am 18, 5'10, 160lbs, very athletic, very fast metabolism, very little body fat, etc..

if i take some hits on friday, what do you think my chances are of testing clean by monday? i know the only way is to test myself, but im just seeking info from others. also, i should be STOPPING exercise on the weekends? what about eating brownies? does that take longer to get out of your system? is there any chance of excreting some of the THC you inhale through fiber or something?

i know you have all read these questions about a million times, but for my own sanity i just wanted to make a post for myself. i've read posts as old as 2004, so i've done some pretty vast research, but i just added a couple other questions in there that weren't exactly like what i was wondering from other posts. any help would be appreciated my sanity depends on your support >< im scared. THANKS ALOT!
