You can say it all you want, but it's a very deliberate lie, or an expression of astonishing ignorance.
I doubt you have the intellect to comprehend this point, but a government must first and foremost be capable of SURVIVING. A government which tolerates widespread usage of drugs cannot survive, and will be replaced by a dictatorship after that society collapses. It is as predictable as the sun, and it is exactly what happened in China.
One of the arguments we constantly make to the Socialists/Communists is that "this idea has been tried many times in history, and it always fails."
Well i'm pointing out the same thing to you. Legalized drugs has been tried before, and it was a horrible disaster with consequences that are still affecting us today. It didn't work in China, and it didn't work at Platzspitz in Switzerland.
"Needle Park" was an utter disaster.
