In that case, the outcome will only be validated by a saliva cotinine test device. 2. If participants use NRT, the outcome will be validated by exhaled carbon monoxide only.
6-month follow-up

ACTIVE COMPARATORInterventions
Ask about smoking history; Warn about the high risk; Advise to quit; Refer smokers to smoking cessation services (with a referral card); Do it again
The contents of the leaflet include (1) highlights of the absolute risk of death due to smoking; (2) the whole list of diseases caused by active and second-hand smoking; (3) ten horrible pictorial warnings of health consequences of smoking and second-hand smoking in one page to maximize the impacts; (4) benefits of SC and (5) simple messages to encourage participants to quit smoking and remind them to call the Department of Health SC hotline 183 3183.
The contents consist of brief information and highlights of existing SC services, contact methods, motivation information, and strong supporting messages or slogans.
The contents include information about the benefits of quitting, smoking and diseases, methods to quit, how to handle withdrawal symptoms, declaration of quitting, etc.
Each IM chat group will consist of a trained SC counselor (HKU staff), a peer supporter (former smoker), and a participant (smoker). The 3-month group chat-based intervention will consist of regular messages and real-time support through group chat. Regular messages will generally include goal setting, health warnings, abstinence support, positive psychological exercises, and encouragement and will be delivered in a tapering style. During the real-time chatting, SC counsellors and peer supporters will provide real-time chat-based support, and peer supporters will share their quitting experience as appropriate.
Regular e-messages via SMS at twice per month within 3 months (total 6).
