I'm all for that, whatever the intoxicating substance. But it certainly doesn't mean that one intoxicating substance should be legal while a less addictive intoxicating substance is illegal.
Now as to the silly remark that we cannot allow alcohol but suppress drugs has a multitude of hidden premises. Besides we discriminate in the application of criminal law all the time; i.e. Petty Theft is not treated the same as killing while lying in wait, killing by torture.
There is simply no basis for allowing substances such as drugs and it is not worth while bandying words with drug addled brains. Once simply commands them! One does not debate, discuss or "express different points of view"with the addicted whether alcoholic or drug. There is too much shrieking and moaning over the bad elements in our society.
