Daddy knows best, kids - part 2

So, on to drug laws. I suppose the best way to start any discussion of our government's "War on Drugs" is to point you to Wikipedia's article on alcohol prohibition in the United States. You can skip ahead to the "End of Prohibition" section if you want to get to the meat of the horrible effects alcohol prohibition had on the country; things like organized crime, racketeering, police corruption, and murder became rampant due to the massive black market opened up by the ban. The quality of alcohol dropped and the potency increased, due to its being more profitable to manufacture and transport high-test liquors (moonshine), causing illnesses and death.

Does this sound familiar? How often have you heard in the news stories about drug-related police corruption scandals, drug-related gang turf wars, mafia involvement in the drug black market, etc.? There is good reason to believe that most drug overdoses are due to the varying purity of street drugs - a user may prepare what seems to be a reasonable dose, only to discover (too late) that the batch of whatever drugs they purchased is much purer than they expected.

All in all, the bulk of the "drug problem" in this country is because of the drug laws, not in spite of them. Were these drugs legal to manufacture, sell and use, there would be no black market, no massive profits for organized crime. Dosages would be easy to determine, violent crime rates would plummet as they did after the end of Prohibition in 1933 (and they continued to drop for 30 years!).

To wrap this back into the point I made in part 1, can anybody explain to me why it's wrong to use drugs recreationally? I'm not asking about the legality, but the morality. I just don't see it.
