1) How long does it usually take till youre back to normal when using cocaine? 2) How long does it take after snorting cocaine, before the effects show? And how long should you wait, before you are certain the first line wasnt enough, and that you have to snort another? 3) How difficult is it to pretend to be ordinary, when youre on cocaine (how easy is it to hide?)? 4) Is there a difference between a) cocaine, b) coke and c) crack, or is it just all the same?
