The libertarian position on drugs, is like the one on abortion, zero restrictions.
No restrictions of any kind, not on current drugs, not on any drugs or drug combos (cocktails) that people or cartels invent or create, no limits on advertising and marketing of those drugs, nothing.
There are hypocrite ones that’ll only want pot legal, and some others not. Basically only wanting the ones they want to use legal.
The rest are just crazy.
