Regardless, the Scientific American blog outlines an interesting catch-22 in the US - a country that tried unsuccessfully to ban a problem-causing drug known as alcohol. I wonder how our country would fair if pot was legalised? Pizza Hut would be surely smiling and teenagers would need to use something else to rebel with. Maybe we should follow the Dutch and see what happens. But then again, I hear they're thinking of changing that. Strangely enough, the powers that be aren't usually regular takers of the stuff. Another catch-22?
