A key factoid in this decision; it seems to have worked in Portugal – where “worked” is “reduced not only the harmful effects of the Drug War, but actually led indirectly to lower drug use overall”, provided you believe the numbers:
A 2014 report from Transform Drug Policy Foundation found the total number of people in Portugal who had used drugs at any point in their lives rose after decriminalization in 2001 through 2012, but the numbers of people who had used drugs at any point in the year or month before they were surveyed actually decreased, meaning fewer were using drugs on a regular basis.
Drug-related deaths, cases of HIV and AIDS among drug users and general rates of drug use all sharply declined from 2001 to 2012 in Portugal, the report found.
On the one hand, you might say “Of course research from the ‘Transform Drug Policy Institute’ is polllyannaish on legalisation!”
To which one could respond “And countervailing research by government will be no less bias, since the “drug war” is a make-work program for cops, corrections staffers and prosecutors”. (and the millions in dues they pay every year to “progressive” pols).
The “war on drugs” has killed more people than the Vietnam war, to less positive good for everyone (but the law-enforcement-industrial complex).
