What I am guessing is. He will buy you a 20 sack from his dealer. then take just a little bit out of it and then show up after school and give you your sack. or he could get hooked up by his dealer so he will be taking the weed he gets hooked up for and then giving you the normal amount people get for 20 bucks. but usually if someone helps you out with bud you should smoke a bowl with them or something.
You got robin taxed which is when a someone pinches off your bag for the effort of getting it for you. It's not bad when there not pinching that much but believe me if it's not someone who you know very well they will pinch as much as they think they can get away with. Which is why you wanna find your own connection.
Ah okay, good to see the headaches are "normal" And i'm not sure if i'll be dissecting the joint anymore, but maybe! I'll have to see if i'm able to make a decent pipe first, and i wouldnt be able to dissect it until im home alone, the smell is extremely strong! i cant even open the plastic container its in, with out smelling up my whole room within seconds! and its just one little joint! But i'll see what i can do lol
