The effectiveness of plain packaging in discouraging tobacco consumption in Australia.

The removal of all branding and promotions from tobacco products, known as 'plain packaging', is intended to decrease tobacco consumption. Here we examine the effectiveness of Australia's plain packaging law, which coincided with a change in graphic and text health warnings, by using nationally indicative data 5 years post implementation. We measured the effect of the law on smoking prevalence, tobacco expenditure, expenditure intensity and quantity of tobacco consumed, using New Zealand as a control country in a difference-in-differences research design.
