Right, but it's not only making the drugs legal, since that way they would only get cheaper, but would still be around. It's about making them publicly founded - free for the drug users. The entire distribution chain should fall down and many of the production facilities would become unprofitable and close. For example, the cost of growing ten tons of opium poppy is comparable to growing ten tons of wheat, or corn, or any food. Today, some of the 3rd world countries prefer to grow opium poppy because it's more profitable and all the production-distribution is therefore criminalized. If the consumption goes down (and it should because the present drug users will die and not so many new ones will join), so the production of opium would shorten as well vacating more land to help the food shortage in those 3rd world countries. That's much more economic for the developed-state governments than keeping the expensive army of 'fighters with drugs' with all their equipment, expensive rehabilitation centres with little to no success, and at the same time sending the food and monetary relief to the 3rd world countries. (Another strange 'fight'. The developed countries send food and money knowing how criminalized the 3rd world countries are, and that the food and money would mostly be taken by the warlords to support their armies and purchase weapon. Also, if the food is sent by the developed countries, why to bother growing food of their own? Let's grow the poppies, right?)
