I am probably echoing what has been stated by many others. Drugs shouldn't be legalized/illegalized based on harm. All drugs have the ability to cause harm. In a free society, individuals should have the right to decide what they use and don't use- I see this as a fundamental human right. Moreover, and most importantly, the war against drugs has caused much more harm to individuals worldwide than the drugs themselves. I have said this before, and I will say this again, the ultimate form of harm reduction would be to end the World War on Drugs. This is fundamentally a war against individual human beings. In terms of addiction, if you subscribe to the belief that addiction is a disease and that a percentage of users will naturally become addicted to drugs, then subjecting addicts to criminal punishment is tantamount to subjecting a minority group to repression and persecution and doing it in a manner that state sanctioned and socially acceptable. This is just as bad as throwing people in jail for race, religion, or sexual preference would be. The perpetrators of this war are guilty of Crimes Against Humanity.
I am a US citizen, and as such, I can also say that drug prohibition is a violation of founding spirit and principles of this country. A philosophy that values self reliance, limited government, and the rights of man. As such, architects of the drug prohibition in the USA are traitors. Yes, the United States might have played a leading role in perpetrating and perpetuating the War on Drugs

and this is why it has an even greater responsibility of being the first country to take a leading role in ending the War on Drugs. I think this would do more, than anything, to repair our image world wide. Too bad I don't see this happening anytime soon or even not so soon.
