i've seen a friend doing what i assume is coke. it was small, white, in rock form and crushed into a powder. i'm wondering if this was crack or if it was uncut coke. i sneeked a taste while they were out of the room. it tasted very bitter and made my mouth numb. also, i keep reading that crack cant be crushed down and snorted, but i've read on other websites that it can. i'd like to know if anyone does this. i know crack is cheaper than coke, so i thought this would be common. also, how many lines would a small rock make. any information you can give me on coke would be great.
