Roscoe P. Coltrane? Sorry, I lost you in the "Night of the Living Pings". A google search yields tons of results, alot of which are crap, but some of which are enlightening. From the CATO Institute: "Total drug arrests are now more than 1.5 million a year. There are about 400,000 drug offenders in jails and prison now, and over 80 percent of the increase in the federal prison population from 1985 to 1995 was due to drug convictions. Drug offenders constituted 59.6 percent of all federal prisoners in 1996, up from 52.6 percent in 1990. (Those in federal prison for violent offenses fell from 18 percent to 12.4 percent of the total, while property offenders fell from 14 percent to 8.4 percent.) Yet as was the case during Prohibition, all the arrests and incarcerations haven't stopped the use and abuse of drugs, or the drug trade, or the crime associated with black-market transactions."
Of course, what I'm talking about here is legalization of marijuana, not harder and more volatile drugs like cocaine, pcp, etc.
