Pain medications, for example, would have to also be completely banned for even medical use, since it's impossible to ensure not a single one is ever misused. The line between medical use and recreational use is not sufficiently clear to establish a society that was drug-misuse free. Many life-saving medications are psychoactive and thus subject to misuse. A drug free society would be one where there would be immense suffering.

There are no examples of cultures that included the use of intoxicants and then successfully eliminated the use thereof. There is no indication of a drug free society being possible in the future.
