Selection of Nicotine Therapy to Increase Quitting

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants will be randomised to a selection box of NRT or current practice. Telephone counselling and advice will be available to all participants in the usual manner, via Quitline.

Selection box group: Participants will be sent a box containing four different NRT delivery methods, namely patch (21mg), gum (4mg, fruit and mint), inhaler (10mg), and sublingual tablet (2mg), along with a culturally appropriate video/DVD and printed material. Participants will be asked to try out each product over a week prior to their quit attempt. Participants will then be contacted by telephone and asked to choose one or two preferred methods of delivery to use for eight weeks after their Quit day.

Treatment: Other
Comparator / control treatment
Control group: Participants in the current practice group will be supported by Quitline in the usual way for an eight week period, with NRT provided as required in the form of patches (7mg, 14mg or 21mg) and/or gum (2mg or 4mg, mint or fruit).
