well when you break anything down to its purest form it becomes much more abusable, but the OP was asking about coke. and even when matched up against crack, i'd still put meth ahead of it. and although crack is about the same price as meth(at least around here it is) what you buy lasts longer and the high is more enjoyable, and i mean that in the absolute worse way possible.
OP you honestly got some weak, stepped on bullshit, but hey if that's what it takes for you to make the decision to leave it alone then write your dealer a thank you note
in regards to shooting coke, the only thing that will make you go broke quicker is literally giving all of your money away. i've been saying this since i IVed coke for the first time, there's something to be said about the addictiveness of coke when you IV, it literally turns into a different drug when you put it into your vein. the difference is so stark it scared me and i swore i'd never IV coke again. so take it from me and thousands of others and stick to insufflating if you're going to ever give it another go. just try to find some scale this time, i promise you'll change your outlook.
