I've been trying to force myself to accept the pro-drug element of "Libertarian".
While you are on the way, let's get the terms straight. It isn't "pro-drug". It is "pro-reform". You know, you don't have to be "pro-alcohol" to recognize that alcohol prohibition was a disaster. If you are against alcohol prohibition, does that mean you are "pro-alcohol"?
In fact, alcohol causes more crime and other problems in society than all the illegal drugs combined, by several orders of magnitude. That doesn't mean that alcohol prohibition was a good idea. It wasn't. It was a disaster that only made things worse. One of the things it did was give us the biggest teen drinking epidemic in US history. That was one of the major reasons it was repealed. And today, kids report that it is easier to get illegal drugs than legal ones. Historically speaking, the biggest single cause of drug epidemics among children is anti-drug campaigns.
I know lots of people who have never touched an illegal drug in their lives, and have no intention of doing so, who support reform of the laws. One of them is a judge who used to be a Federal prosecutor and once held the record for prosecuting the largest heroin case in US history. Another is a Federal judge who was Nixon's chief of drug enforcement in the southwest and, as a judge, presided over the largest cocaine bust in US history. (20 tons in one warehouse).
As one part of his learning experience on the subject, when he got the cocaine case, he asked the police what effect the bust had on the local cocaine market. The cops reported that the price on the streets had gone down after the bust -- indicating there was still a surplus of cocaine in the city. You can read about his experience as Nixon's man at

Another was the head of the pharmacology department at the University of Texas. They gave him the task of finding the lethal dose of THC (the active ingredient in marijuana). He found that, no matter how much they gave to mouse, they simply couldn't kill them with THC. (In fact, another experiment showed that mice who received long-term, very heavy doses of THC outlived every member of the control group.) He said that when he learned that from his own research, he knew that the government was lying about something.
Lying on the issue is, in fact, official government policy, and has been for almost seventy years. If you happen to catch the History Channel Special "Hooked: Illegal Drugs and How They Got That way" you will see a very interesting segment by Dr. David Musto. He recalls a story that Harry Anslinger, head of the Federal Bureau of Narcotics, told him. He said Anslinger went out to a bridge on the Potomac one day, looked out, and saw a field of hemp (cannabis, mj) stretching out as far as the eye could see. (Naturally, because it was a major crop in the area for a couple hundred years.) He knew that he would never be able to enforce the drug laws with his then million-dollar budget, so he figured the only way he could make any impact at all was with the Big Lie. And that's what he did.
I also recommend that you read the short history of the marijuana laws at

and
The Consumers Union Report on Licit and Illicit Drugs at

Both of these are "must-reads" for anyone with any interest in the subject. They will both surprise you.
