Yeah I did an essay for my criminal law essay on the possible legalisation of soft drugs and this was the main piece..My main criticisim of the book is that its too radical it dosen't take into account culture, set or setting which norman Zeinburg bases his thesis...He's not very concrete in regards to how it would work or be controlled.what it does show however is the current system is crazy.....If you want to read more Tim murphy's Article called "The War on Drugs" is very good.
