Cartoon depicts Act leader Don Brash floating along high on a large joint labelled 'Libertarian Beliefs". Refers to his calls for the decriminalisation of cannabis. He said prohibition of the drug hasn't worked, and policing it costs millions of tax payer dollars and clogs up the court system. Same is better applied to most monetarist libertarian policies.
