War on drugs

I have to do a power point slide on the war on drugs. The thing is that the questions I have to answer are hard to find the answers too. I have looked on the internet and I am feeling that maybe I have looked over something. So I need some good pointers on this question if any body has any and or some good web sites to look at for the information I need.

War on Drugs

1. Are the current laws and policies effective? Why or Why not?

2. Are there any drawbacks to your solution?
