Tobacco & Addictions

Tobacco & Addictions Research


Tobacco 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 theme 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.


Our current research highlights


A randomised-controlled clinical trial designed to evaluate the effectiveness, utilisation and safety of combining nicotine patches with e-cigarettes (with and without nicotine) plus moderate intensity behavioural support, on six month smoking abstinence, in smokers motivated to quit.

1,809 participants are being recruited from the Auckland region of New Zealand and randomly allocated to one of three groups:

  • 21mg nicotine patch daily, or
  • 21mg nicotine patch daily plus a ‘new generation’ cartomiser e-cigarettes with no nicotine, or
  • 21mg nicotine patch daily plus a ‘new generation’ cartomiser e-cigarettes with nicotine

The project is funded by the Health Research Council of New Zealand and was designed in collaboration with external investigators:

  • Dr Murray Laugesen, Health New Zealand Ltd, Christchurch
  • Dr George Laking

The SPGeTTI project builds on the teams previous work developing a smartphone APP designed to deliver a package of tailored support messages and information to problem gamblers and for use by problem gambling treatment providers. There are 5 inter-related components in the SPGeTTI Phase II project:.

  • Estimating smartphone ownership and patterns of use among people with problem gambling.
  • Estimating likely recruitment, retention and sample size for the trial.
  • Developing content, features and functions.
  • Testing content, features and functions for face validity and acceptability, technical refinement and testing.
  • Randomised controlled trial.

The project is funded by the Ministry of Health
