Evenin' ladies and gents, and a happy new year! I've just rolled up a generation joint, and I was wondering just to what extent previously-jointed weed collects and retains THC from the smoke that passes through it in the joint. I remember one morning after a party I lit up the last 1/2 inch of the blunt we'd smoked the night before, and I got higher it seemed off that 1/2 inch than the entire thing from the night before. What's the good word on this phenomenon? Thanks!
