The Nobel Prize in Economics 1976, Milton Friedman was in favor of legalizing drugs and he had two problems: one economic and one philosophical. The first because the cost of the drug war is a billionaire, while, the second is that no individual should be deprived of choosing what they consume. The proposed regulation should be implemented to the new model of consumption (to reduce the risks of a drug on the market as many people die over illegal by quality of the drug) and this new model would provide more money to a nation with this business tax is now legal. (This money could be allocated to cover the fiscal deficit).
There are several voices who point to the legalization of drug use (and hard candy) with interesting approaches that dates back a decade ago, but governments have preferred to swim against the current. We must not forget that the drug problem must be treated as one of moral and medical, rather than legal.
education in homes, schools and universities and most importantly persuasion are key elements to prevent the solution is worse than the disease. The drug business is good because it is simply illegal, the more illegal it is, the business better.
