The role of cannabis smoking in the development of lung cancer
This epidemiology study was undertaken in response to the high prevalence of lung cancer, and the high use of cannabis in New Zealand. Through a network of collaborators in Dunedin, Christchurch, Wellington, Hutt Valley, Palmerston North, Hawkes Bay, Tauranga and Hamilton, young people with lung cancer were identified and studied. Control subjects randomly selected from the electoral role were also studied as a comparison group. This study identified that long-term cannabis smoking is an important risk factor for lung cancer in young adults.
