again: there's a difference between finding a puff here and there (my usual habit) and chronic exposure to high-potency strains of the stuff hourly for months. habitual marijuana use makes you lazy and stupid - that's not news. what i'm trying to figure out is how long it takes to clear it out.

and, the answer is a long time, apparently.
