"War on drugs" is a terrible world affliction. Prohibition neither works nor is conducive to a better society. Governments should just tax and sell the drugs to the general public. Alcohol is considered to be the most harmful drug but is legal because it can be taxed, controlled, and makes money. ( http://www.economist.com/blogs/dailychart/2010/11/drugs_caus... ) Governments should also support people that want drugs…
I don't see it quite so cynically. Alcohol is legal because there would be outrage or civil unrest if it was banned. Most people that I've met (who may not be considered alcoholics) certainly have some level of alcohol dependency. And, I'm being loose here with the word 'dependency', but in the last year, I've never seen one of my friends or acquaintances refuse alcohol at a bar or restaurant, while others were drink…
There is outrage and 'civil unrest' in some sort surrounding other drugs; the difference is the communities in which it manifests.
The war on drugs very disproportionately affects people along lines of race and socioeconomic status[0]. These communities certainly are outraged at how their families and communities are being destroyed (literally) by the prohibition of these drugs and the societal ramifications that go along with the prohibition. The difference is that they're not in a position to voice that outrage as loudly.
Remember why prohibition of alcohol was repealed - wealthy taxpayers were mad that their tax bills went up after the passage of the 18th amendment (the government could no longer make revenue off of alcohol taxes). This is exactly why initiatives to legalize marijuana in Colorado (Amendment 64), Washington, and California (Prop 19) have used the language 'tax and regulate'. It's not some crazy new idea - it's literally the same tactic that succeeded in passing the 21st amendment!
