A Problem with Smoking Bans

The New York City Council has voted to ban public smoking:

In addition to parks and beaches, the bill also specifically prohibits smoking in the following areas:
• pools,
• recreation centers and
• all other property, equipment, buildings and facilities under the jurisdiction of the Parks Department.

The bill also prohibits smoking in pedestrian plazas, which are areas designated by the Department of Transportation for use as a plaza and are located within the bed of a roadway and may contain benches, tables or other facilities for a pedestrian to use.

I don't know if this applies to substances other than tobacco.

The real problem is that a policy of cracking down on declining vices gives anybody with a vice an incentive to promote it in order to prevent a crackdown. Beans eaters, for example, are taking notes.
