i read sumwhea (which i did a ton of every site tryna figga out da best way to take my test yestaday) that the smoke in the air, doesnt contain the "metabolites" so 2nd hand smoke dont happen... my advice to u is smoke and live it up, if you going for a job its illegal to moniter you so da best way is to substitute sumbodi elses piss if you gotta clean friend... look at the thread below yours, the last dude goes into much detail how you should sneek in sum donor piss... it worked fa me... all you need is a thermometer, condom or small shampoo bottle, and a lil practice....
