how many grams should a experienced smoker need to feel FUCKED for about 4-5 hours? someone who smokes a 1/8th in about 5 days (2 times a day). an 1/8th?

Also i went to kindred cafe, and had 2 shakes. was high (but not like tripping out hard or anything). i wanna get to the point where i trip out hard for about 3-5 hours.

... or longer
