I see little merit in the health issues when legalization of drugs is considered.
I feel a far stronger argument has to do with effect on society of people having to commit far greater crimes to obtain the money to buy the illegal drugs (that obviously cost far more than if they were sold legally).
Well over half of the people in the US prison system are on drug related offenses: Murder, Robbery, Burglary and of course those involved directly or indirectly in the sale of the illegal products.
I would rather see an addict in a controlled environment get loaded than doing so on the street corner. I would do the same with prostitution: legalize it like they do in many countries in Europe or here in parts of Nevada. I would rather see a guy (or girl) walk into a building for sex than hanging out on the corner.
