HARMONY (HARM reduction for Opiates, Nicotine and You) Trial: Protocol of a Randomised Controlled Trial of the Effectiveness of Vaporised Nicotine Products for Tobacco Smoking Cessation amongst NSW Opiate Agonist Treatment Clients
Introduction Tobacco smoking is a major cause of preventable disease in Australia. Individuals receiving opiate agonist treatment (OAT) are a group who experience high tobacco-related morbidity and mortality rates. Despite reporting a desire to stop, relapse rates in OAT clients are high and cessation attempts supported by pharmacotherapy are less effective than in general populations. New and innovative ways of addressing smoking amongst this group are needed. Vaporised nicotine products (VNPs), or e-cigarettes, may reduce a person's exposure to toxicants and carcinogens when compared to tobacco cigarettes. High quality evidence indicates that VNPs can increase rates of smoking cessation compared to nicotine replacement therapy. Pilot results of VNPs as a smoking cessation aid in OAT clients suggests their use is feasible and acceptable but effectiveness in this group has not been explored. This protocol details the rationale and methodology for a randomised controlled trial to examine the effectiveness of VNPs for tobacco smoking cessation amongst OAT clients in New South Wales, Australia.
