what do you mean by grade coke....Grade A coke?.....the shit i get is almost too strong to put in your mouth, no joke. you kinda gag when putting a pinky's worth on your tongue. one line is def enough to get you up pretty well, even for those very experienced (even daily users). its of a yellowish tint, and of course its cut, since all coke is, you can tell that there arent too many or too strong additives mixed.
