I dunno if alcohol is so much worse than weed in the grand scheme of things. A lot of Europeans, especially up north, are downright alcoholics by US standards, and yet their societies seem to be doing just fine, quite flourishing really.
For example Ireland has the highest GDP/Capita in EU and Finland has the best educated school students in the EU.
Not promoting alcohol consumption, but from my POV here in Europe, traditional alcoholic societies seem to have developed further than traditional stoner societies.
Just a shower though.
