A total smoking ban in prisons comes into effect from July 2011. The ban, introduced by the Corrections Minister, Judith Collins, aims to provide a healthier environment for prison staff and inmates through the elimination of secondhand smoke. Overseas experience has shown that simply banning smoking will not necessarily result in prisoners giving up, nor will it result in the maintenance of abstinence by those who do stop smoking during incarceration. In order to reap maximum health gains from the total smoking ban in prison policy, comprehensive cessation support for all inmates needs to be provided to ensure that they quit during incarceration and continue to abstain from smoking upon release.
