If drugs are a crime and you do not want them to be, change the law. If you are attempting to stop drugs from entering society then stop it. The fact is there is a market for drugs. It is not pursued by free open market enterprise so, it is pursued by black market interests. That is a seedy side of the coin. See Chicago. That is where all American population centers are headed. It is the drug market creating these problems. Stop the drug market. There is a lot of influence, money and power behind it so, ask yourself why it still exists. Because those rich, powerful, influential people want it to exist.
