Naw a foilie is when u take like 75-200mg cocaine , about half that amount baking soda, mix em together on foil then add a few drops of water mix em together and smear it all over like a 7x7 inch piece of foil, maybe a bit bigger so u have an area to hold it, then while it's still damp it u take a lighter and circle it around underneath until u see it kinda become a bit clearer but without letting it smoke and then after that u take ur toot and light it from underneath but now closer and u can get some massive clouds of smoke coming up into ur 2l cut pop bottle toot lol. I don't know, it works for me, maybe I should learn how to properly rock it up although that'd be the death of me.
To the op, if ur gonna try shooting start with 40-50 mg.
