Shit....I might have to take a drug test next week for a job and I smoked last night several hits. I really want to smoke again tonight, would it be a bad idea? Prior to yesterday, I last smoked 3 weeks ago.
I don't know if he's 'truly fucked.' I've taken a drug test about a week (or less) after a single session and passed with flying colors. Not everyone will, but its possible. If the OP is a fatty, then its not as likely.
Thats all I feel like saying though, as sega said, no drug testing questions are allowed here.
