can you crush it up and snort it? and is it bad to take if you have to go to class or work?
You can, it wont last as long though. Until you are familar with the effects you probably shouldnt do it at school or work though you should be able to function 'normally' in such places and it definately makes school/work more enjoyable.
The only things others may notice are dilated pupils, sweating and you talking a lot.
Since you can't be sure of the exact contents of the pills or your individual reaction to it a safe environment with friends is best the first time.

try sticking one up your ass?lol!i had a friend who tried that once and she swears it was great?
Rectal administration is actually very efficient.
