Smoker's License

Here's an idea from a down-under academic.

A public health proposal suggests that tobacco smokers should be required to apply and pay for a “smoker’s license” in order to continue buying cigarettes.

Simon Chapman, a professor at the University of Sydney, proposes that users would have to apply and pay for a mandatory license in the form of a smartcard that would be shown when buying cigarettes. ...

In a controversial move, the smartcard would allow the government to limit how many cigarettes a smoker could buy.

I wonder what the penalty would be for possession of cigarettes without a license.
