Okay, i'll probably be smoking for the first time soon and was wondering. Overthinking things a little...but. If i smoke once, not too much, couple hits from a joint, bowl, whatever and have a drug test coming up say in 7 days (not really just an example). will my levels of THC in my hair, blood, urine, or saliva be so mild that i can argue that it was the second hand smoke from me hanging out with my friends hotboxing the room or something like that? Based on the common cut off level, would i be okay? All helpful answers are appreciated. Also will me smoking a moderate amount just this once cause me to fail with a 7 day clean period? Thanks
