Current smoking cessation interventions are focused only on smoking behaviors, and drinking habits are generally overlooked. The aims of the project is to examine the feasibility of implementing an integrated smoking cessation and alcohol abstinence intervention in young Hong Kong Chinese smokers.
The study is a three-arm randomized controlled trial. (1)The standard treatment group , participants will receive a brief smoking cessation intervention based on the '5A' and '5R' model, then the RA will assist the participants to quit smoking using the STAR method. (2) For the alcohol intervention group, participants will also receive a brief smoking cessation intervention with the models as the ST group. After that they will receive a brief advice on alcohol use based on the FRAMES model. Then the RA will invite participants to complete the Alcohol Use Disorders Identification Test(AUDIT). (3) For the Control group, participants will be provide with two leaflets, one for smoking cessation and another for alcohol abstinence. All the data collection will be conducted at baseline, 1 week, 1 month , 3 months and 6 months for follow up.

Adolescent will receive a brief smoking cessation intervention based on the '5A' and '5R' models. Then the research assistant will ask about their tobacco use and assist them to quit using the STAR method. A booster intervention will be given over the phone at 1-week, 1month, 3-month, and 6 month follow-up.
In addition to the brief smoking cessation intervention based on the '5A' and '5R' models, the participants will receive brief advice on alcohol use based on the FRAMES model. Then the RA will invite participants to complete the Alcohol Use Disorders Identification Test and provide personalized feedback. There will be a one to one, 20-30 minutes semi-structured interviews with 30 participants. Participants with high(N=15) and low (N=15) adherence will be purposively selected. A booster intervention will be given over the phone at 1-week, 1month, 3-month, and 6 month follow-up.
