Second--Just because something is deemed "illegal" by society doesn't necessarily make it wrong. It was "illegal" for women to vote at one point.
I too have regularly made the point that legality & morality don't always meet. It drives me nuts when somebody says something is wrong because it's illegal; I gather they don't understand what a circular argument is. It's wrong because it's illegal and it's illegal because its wrong and...there we go into an endless loop of illogic.
Alcohol was illegal from 1920-33 as well, yet today it's so socially accepted that drinking is depicted in many (if not a majority) of TV shows and movies. And those TV shows are regularly supported by beer & liquor ads. From so evil it must be banned to suitable for prime time viewing.
In 1950 a woman who wanted to lose a few pounds could easily have gotten a prescription for methamphetamine from her doc to help her keep her figure. Today meth is so evil you're treated as a criminal should you dare want to buy a nasal decongestant, having to present photo idea and sign a log with all your info entered into a data base for potential DEA viewing pleasure.
Neither substance has changed, but the view of them sure has.
I will point out something I have said on SAS a million times--the fact that liquor is legal and pot isn't is complete insanity as pot is so much more benign than alcohol.
Yes, it's insanity for sure. Liquor is legal for two major reasons I can think of. It's impossible to stop the production of it when the precursor to it is literally everywhere. You can make alcohol from basically any food crop there is: corn, wheat, barley, rye, potatoes, grapes, sugar cane, apples, citrus fruit, rice to name just a few off the top of my head.
The DEA can burn down a field of pot. They can't burn down the entire state of Iowa to remove corn fields that could be made into vodka, whiskey, etc....
Secondly, alcohol is accepted because it has a very long & rich history in Western civilization. Germany being famous for their many centuries of brewing beer. The French being famous for their tradition of wine making. Whisky is so much a part of European culture that we have Scotch -- whisky named after a nation!
