You keep referring to alcohol. It causes massive problems because it is legal. Legalizing other drugs is obviously not the answer. You are refuting your own argument.
Beverage alcohol was once illegal. But alcohol
Prohibition was repealed because it made the situation infinitely worse.
The
War On Drugs is in fact another
Prohibition -- which is in fact equal to if not even worse than the destructive nature of alcohol prohibition. The War On Drugs has been going on for over forty years and it has been a monumental waste of money, government resources, and millions of ruined and lost lives. In spite of all of the wasted effort any recreational drug that anyone wishes to buy is readily available within a few miles of any inhabited part of the U.S., usually within a few blocks, and drug use is more prevalent today than it was before Nixon started this fiasco.
The only way to effectively reduce the use of recreational drugs is presently being practiced in the Philippines in the form of random, cold-blooded murder of anyone suspected by any police official or civilian vigilante of selling or using recreational drugs. So the president of the Philippines has opted to substitute corpses in the streets of his towns and cities for the practice of recreational drug use. This situation is categorically insane -- and our President Trump has complimented Philippine President Duterte for imposing it.
How do you feel about it?
