I need to find under ground web sites which educate users on various substances, can anyone help me, I only want the info for research to help me with an understanding of how and what various substances are made from etc etc, I am a student in the addictions feild and believe in harm minimisation approach, but if i have the knowledge then I have a better understanding in this field. Please send links to various sites no crap please.
