No they do not, but they do answer the question you posed to me.
I have been saying this repeatedly, after we get a grip on our criminal problem caused by prohibition, we will then be in a position to deal with our DRUG problem.
That is, as you stated, your opinion, it is not backed by real life data however. I could list a ton of studies and a ton of quotes backing the position that legal status of drugs have little to NO impact on rates of usage, but I will just provide one.
if you are really wanting to be honest in your evaluation of this issue look here:
Drug Decriminalization in Portugal: Lessons for Creating Fair and Successful Drug Policies | Glenn Greenwald | Cato Institute: White Paper
If you want to take the lazy way out then just read the intro and the conclusion of the paper that is at that link, although in its entirety it is very revealing.
Since 2001 All drugs have been decriminalized in Portugal. This includes Heroin, cocaine, methamphetamine, you name it, they ALL can be used with ZERO legal repercussions. 9 years for the drug crazed zombification of their nation to develop, and it did not occur, the drug problem did not get worse, it got BETTER, significantly so.
If you want to do even more leg work, look at Swiss heroin distribution (as an interesting aside there is a thread here at DP wondering why they have the lowest crime rate of any nation ), or even at the more recent UK model of government sanctioned heroin distribution, look at how both countries are ecstatic over how successful the programs are at actually dealing with and addressing the
problem
Not just my opinion, but yes, we are making crimes out of things that are not crimes - just as Abe points out in my signature with his "Fine words"
