Decriminalization of marijuana in Chile

After senator Fulvio Rossi declared to smoke marijuana one to two times a month a heavy debate was opened about the legality of drugs in Chile. I was really pleased to know this topic was being treated in the congress and even though I'm not a marijuana smoker and I'm not even interested in becoming one, I feel the need to remark the liberties we were supposed to be given at birth. Freedom is one of the most important values in Western societies and it must be respected as such. The prohibition of drugs becomes a serious issue for big cities, and its people. It helps to make ghettos appear and the police fails to prevail a State of Law due to the power of the big drug dealers. There's another situation I'd like to point out, the congress arbitrarily decides which drugs are legal and which are not, and I think that's really unfair. I mean, why is alcohol and tobacco still legal if they are the drugs which kill most people every year, and it's the number one cause of heart and lung related diseases in Chile. Milton Friedman stated that all drugs should be decriminalized due to an economic law which explains that as long as there are people willing to get either a good or a service, legally or illegally, there's always going to be supply. That means, that a regulation of marijuana will not reduce its use, it would only make it harder and more dangerous to get. This will only enrich dealers and make ghettos more criminal. Recent studies about countries which decriminalized marijuana prove that the consumption has not increased, it has in fact decreased. It's reasonable to conclude that out, because as marijuana is consumed in public places where everyone can see, people can actually see the disadvantages of smoking pot from a young age. Furthermore, prevention is also a better way to fight drug usage. On the other hand, I haven't explained why I used the word "decriminalization" instead of the so-called term "legalization" There's a huge difference between these two words. One could easily think they stand for the same thing though. Actually, it's not so. Legalization would mean the regulation of drug usage with laws regarding where, when, and how drug usage could take place. Decriminalization eliminates all laws and prohibits the state and law-enforcement officials from intervening in any drug usage-related activities or transactions, unless other laws apply.
