Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Phase 1 Group A: Tobacco Quit-line (TQL) Group
Participants will be referred to the TQL and will be followed up for up to 12 months.
Tobacco Quit-line
The TQL is free, and the TQL counselor will provide three phone counseling sessions lasting approximately 15 minutes to devise a specific plan to quit smoking and arrange the delivery of 4 to 12 weeks of NRT based on need. Participants will be advised to request nicotine gums instead of patches to accommodate their job circumstances.
Phase 1 Group B: Brief Behavioral Counseling Group
Participants will receive one brief behavioral counseling session and two phone call follow-ups, then be followed up for 12 months. Besides the counseling session, they will be provided with Nicotine Replacement Therapy (NRT) and a referral to the TQL.
For the NRT, participants will receive one box of Nicorette nicotine gums, 2 mg or 4 mg (depending on the number of cigarettes smoked), as well as 8 additional gums for a total of 168 gums during the counseling session. This amount is enough for 3 weeks. An additional 3-week supply will be provided at the second follow-up.
Nicorette
Participants will receive a 6-week supply of nicotine replacement treatment (NRT). Based on participants' self-report on the number of cigarettes smoked, these are the possible dosages of NRT gum (2 mg and 4 mg). Participants should not smoke and use the nicotine gum at the same time. Nicotine gum should only be used when cravings for cigarettes arise and should not be treated like regular chewing gum. It is not to be constantly chewed
NRT will be distributed based on the treatment condition.

Brief Behavioral Counseling
The counseling session will discuss preparing to quit, coping with job-related stress, getting social support, the "5A's" for preventing relapse (Avoid, Alter, Alternatives, Anticipate, and Active), proper use of NRT, and last approximately 30 minutes.
Phase 2 Group A: Second Tobacco Quit-line (TQL) Group
Participants from Group A who did not quit smoking at the 3-month follow-up may receive a second referral to the TQL and will be followed up for up to 12 months.
