A couple of my own thoughts:
1. Could be a stepping stone to banning tobacco altogether.
2. Prohibition of substances doesn't tend to work, especially of they aren't going to make it illegal to possess.
3. Throws some cold water on Nigel's predictions of MJ legalization. Maybe it's a completely separate issue, but not encouraging.
