Most conservatives or right-wings worldwide oppose psychoatives legalization, why such unanimity on this topic? I find it strange that there is such a consensus. Do you know why?
Personnally I don't know. They pretend to be for individual liberty/responsability while honoring for most westerners the so called freedom, but in fact are more like zealous little control freaks closer to ISIS in their way of thinking...
Only Libertarians get the concept of ownership of the body by the individual... it goes to whatever-sex to abortion to "drugs".
It is not problem of free will, you can do what you like. The problem is what comes with the drugs. There are effect of drugs that can be lethal in some situations. Imagine what would happen if you legalize drugs, and children start doing drugs from young age, they would turn it to a burden for society, and in moment when there would be no one to take care of them, slowly we would start dying as a human race.
