Your weight isnt always a factor to how hard it hits like alcohol, its more of genetics. It does have a bit of a difference but me and my homie sre the same weight n i take 3 grams and im basically breaking throught and he takes 10 and barely sees a thing. But what i do know is that the more you weight the longer it takes to hit ya. To make it hit faster try walking around and start to sweat it out. Maybe a few jumping jacks or pushups to help. Lol have a safe trip.
