This is a problem in every legal state and it won't go away by making more draconian laws or pretending that it's not a problem because it's already against the law to smoke in public. The fine in Nevada for instance is $600 and there has been widespread public use there already despite the threat of a heavy fine. In most states people can walk into one of a hundred different places at 10am and get sloshed on liquor to the point that they are a threat to public safety but smoking in public is treated as a worse public threat then that, its all just so absurd.
