No, not the evolution of drugs, but rather evolution from drugs. Let us say that all drugs are legalized. In addition, manufacturers are given immunity from the results of misuse. So, people are able to purchase, at greatly reduced prices, any drug that they want. They can also take as much as they can afford but will only be able to blame themselves if they die.
