Out of all the problems the world faces, drugs are the least important
Keep telling yourself that mate, don't look at actual figures that say an American is 7x as likely as a Chinese or a European to be locked up. And don't dig down to find that one reason for the appealing lead America has in incarceration rates is the war on drugs*. Ignore the fact that there is a heavily armed swat team knocking down your neighbor's door with a battering ram because someone smelt a wiff of the joint he was smoking. So yeah close your eyes and ears and everything will be just fine and dandy in the land of the free (from drugs) and for god sake don't investigate what happens to the children of the 500K pot smokers you have locked up. Don't inform yourself, just lock em all up and let god sort it out, eh?
Given that drug abuse is endemic amongst low-income minorities in America, I can't help but think that drug legalization is a covert form of racism
Now that's irony with a capital "I" - the American prohibition on dope was promoted by the government of the day as a way to get "lazy Mexicans" back to work.
Your hate for junkies and potheads is clearly and democratically expressed in those numbers, but the facts of life are such that prohibition has never worked and never will, all it does it create a huge black market and what that delivers to society is misery in the form of oppression (note the date on the bend), violence and corruption. Those who are still ignorant enough to support it are the moral criminals in the war on (some) drugs, the fact they are a "well meaning" democratic mob is of little comfort to the victims.
you should be ashamed of yourself
Why? I'm a proud grandfather of three, I'm a degree qualified professional and have not been out of work since 1981, I currently earn around twice the national average wage and live on the shores of port phillip bay. I've been a responsible pot smoker since 1977 but it's none of yours or the government's dammed business how or why I abuse my own lungs in my own home. And yes I'm sure my employer and the US government read my slashdot posts, thing is at 54 I'm too old to be ashamed of my behavior and will happily admit to, and defend, my pot smoking (although I don't normally tell people like you, for obvious reasons).
So next time you're at a work party sipping on your free grog, have a look around. One in five of those people will be a responsible pot smoker and according to you they should be locked up, their children made into wards of the state, and their family home/farm sold by the state as an illegally acquired asset (regardless of where the money actually came from or the fact that there was only a couple of plants in a well lit closet).
* - Not sure if the following stats are on that page, but here is your "non problem" in a nutshell..
-The 27 nations of the EU have a population of 500M and a total prison population of 600K.
-The US has population of 300M, a total prison population of over 2M of which 500K are locked up for victimless drug crimes.
