This is a debate currently going on in another board, and it centers mainly on whether or not a pharmacy is allowed to have "fake XX" to give to people who try to steal or forcefully take these pills from the pharmacies. Also, if someone could point me to where I could find this information for myself, I would appreciate it.

I tried running a google search, but no matter what search terms I enter, all I end up is with a list of colleges and courses which teach forensics. I am in the 11th grade and I need info on the chemistry behind forensics. Which means that I dont need info on computer forensics or forensic photography etc etc...

So please give me a list of sites from where I can get my required information. And I need this ASAP, becuz I dont have much time left till the deadline.

Thank u.
