How do I find accurate information and statistics on drug-related crimes?

I am writing a paper on the Effects of Needle Exchange Programs. I have come across TONS of info about the programs' effects on HIV transmission and drug-use, but I'd like to confront the claim that NEPs contribute to an increase in crime.


I know that often times, drug-related crimes in a city with a NEP may become centralized to the area around the program (because that's where the drug users end up being more often), and that syringe possession w/o a prescription is illegal (possibly altering the actual results by Possession of Paraphernalia crimes).


How can I accurately provide data, especially on more than one city, while taking into account these variables? Where can I find this kind of information?





PLEASE HELP!!! I only have three weeks to come up with this information!

I can't guarantee it has what you are looking for but try :

Also do a search on New York and needle exchange programs. If I'm not mistaken they've had programs for 10+ years now.
Reply:Go to the Department of Justice site (search D.O.J.). Check the home page and do a search for "drugs." They do studies on every criminal subject. There is much information to choose from.
