Drug usage is treated too harshly by the law. If you legalized most drugs and regulated them similar to alcohol (which is a drug) and soon marijuana, most of the negative things associated with illegal drug usage goes away. Most negative aspects of drug usage happens as a result of interactions with criminals/criminal empires in order to acquire the drugs. The crime element leads to bribery, corrupt cops, corrupt politicians, killings, etc.. Just look at Mexico and the cartels that have infected the entire country because these shadow organizations thrive under a system where drugs are illegal and they have too much power to be quickly dealt with. Makings drugs illegal with harsh penalties also punishes a segment of the population (poverty stricken individuals) who are already institutionalized and in a downward spiral. Legalization would lead to less drug usage, less criminal involvement, and proper rehabilitating people.
