Alright so swim (not sure if need to use this or not but gonna) is a heroin addict and his method of use is smoking off foil. Swim knows if he starts with needles he’d b dead quick (swim has banged a handful of times tho) therefore he smokes. He’s n New Orleans and hasn’t been able to find any tar so he had to use powder H or chunks off a brick. Swims met a guy who has incredible stuff, so good Hes gonna add cut to it to make it last longer bc shits crazy expensive. Some stuff he gets runs down the foil perfectly (which is exactly what he’s looking for) and some stuff just bubbles up into a pile of char. It still works but wastes akot. Swims not dumb and knows everything is cut b4 it even gets to him. So my question is what causes it to char up like that and not run smoothly down the foil and if he’s gonna add a lil cut to it himself to make it last longer what should he use to make it run instead of puddle up. Also, what would U think the cut used that causes it to char up is? Hope this makes sense and thx for any replies. He’s gettin a 8 ball tmrw and is wondering what he should buy.
