Our Addiction Research

SmokingTobacco smoking is one of the greatest modifiable risks to health worldwide. Each year millions of people die prematurely as a result of tobacco smoke exposure. Most smokers want to quit and many try each year. However, the chances of long-term cessation are low, especially for highly dependent smokers. In an effort to help more smokers achieve the goal of quitting for life, the Addiction Research Programme investigates novel approaches to supporting people to change their behaviour.

These studies test the effectiveness of novel delivery systems, variations of delivery of standard treatments, or novel treatments. The research team includes public health physicians and smoking cessation researchers, and has many collaborative networks nationally and internationally.

The International Tobacco Control Policy Evaluation Project is a longitudinal study of tobacco use in 19 countries around the world, including New Zealand. The principal investigators for the study are based at the Wellington School of Medicine, University of Otago. Several CTRU Investigators are involved in this project and there are over 15 other countries participating in this survey.
