The sad thing is that the repressed authoritarians who want to control everyone and prohibit drug use would likely benefit greatly from some recreational psychotropic experiences under the right conditions. And society would be better off as well for their experience.
Or maybe they're wound too tightly, I could be wildly optimistic.
You're confusing the public-facing values authoritarians claim to have vs what they actually believe.
They use things like religion, scapegoats, and wars (on drugs, terrorism, communism, etc) to whip up support. But it's just a tool. Absolute power for themselves is all they believe in. Many of them are drug users, I'm sure.
