Yearly statistics for the USA. Seems your 'obvious' might not be so obvious for the rest of us.
But then again, I think many 'obvious' things for you are not obvious to the rest of us. Like the muddled thinking related to children: 1st, it's already illegal to sell them to kids 2nd, will kids get them less if they are removed from local retail locations that check ID? Will driving it underground reduce consumption or only increase the dangers of use?
For some, it's obvious that they see it obviously. Others... we see nuance and no clear cut answers. Though many of us dislike such strong and rash positions backed by emotive, reactionary, broad stroke arguments and so little data.
