I'm sorry for disrupting your academia with my silly dilemma but I really would appreciate some scientific reassurance on this: Been off meth for 45 days. Was really tempted to do it the other day, was with a sex bud but didn't do it. Then he said 'blow some meth on my d***' and without thinking, I took a puff and blew out the smoke on his d***. I don't think I actually breathed it in but nonetheless, I feel worried. I had a probationary urinalysis 40 hours after the wretched test. Scientifically, just how much meth could I have absorbed from that one puff? Would it be possible for it to have not been flushed out from my system within the 40 hours? Considering meth's half-life (ooh, look at me go!) of 11 hours, and the miniscule amount I was exposed to, am I screwed?
