Although we disagree on religion, I usually find myself agreeing with Penn Jillette most of the time.
Penn says he never tried drugs. Considering the wide range of things he freely admits to, I see no reason he would lie about that. Despite never using drugs, he supports the legalization of all drugs, not just marijuana and I agree with him.
Unlike Penn, I did try several different recreational drugs. I never found them very recreational though so most of my experiments were very short lived. I stuck with alcohol for a while because it was such a part of my culture, but by the time I was thirty it was pretty much out of my repertoire. Tobacco I still stick with because it's the mildest of all stimulants except chocolate.
Penn's main reason for ending the prohibition on drugs is an issue of freedom. While I agree with him there, my main reason for wanting to end drug prohibition is that it's so grossly ineffective and is the main motivation for organized crime, not only in this country, but worldwide. If we ended the war on drugs, organized crime would all but dissapear in one generation or less.
