Inclusion criteria
Inclusion criteria: 1. Self-reported daily user of ST products at least for the last 6 months or ST use on >25 days in the past month 2. Aged >18 years at the time of recruitment 3. Able to provide informed consent 4. Motivated and willing to quit ST use within the next 30 days.
Exclusion criteria
Exclusion criteria: 1. Self-reported users of any combustible tobacco product (cigarettes, bidis, hookah) or e-cigarettes in the past 30 days or those having carbon monoxide (CO) levels >10 ppm, identified by breath test 2. Pregnant or breastfeeding women 3. Individuals with health conditions that warrant caution in using NRT and have previously been excluded in trials of nicotine replacement in smoking. These will be assessed by participant self-report at the pre-trial screening by asking participants whether they have suffered angina pectoris, myocardial infarction or stroke in the past 3 weeks. 4. Individuals who are already on an existing treatment, either pharmacological or behavioral, for tobacco cessation 5. ST-using individuals with diagnosis of oral cancer.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. Self-reported continuous abstinence to all forms of tobacco (smoked and smokeless) at 26 weeks after the quit date, verified by carbon monoxide breath test and salivary cotinine assessment. Participants will be asked a set of questions (one for each type of tobacco product) asking: "have you used this product at all since your quit date?" The possible responses are: no, not even once; yes, 1- 5 times; yes, >5 times. Participants who report consuming tobacco <5 times since quit date, as well as having CO levels that are consistent with abstinence, will be considered as abstinent. 2. Feasibility of conducting a full trial on smokeless tobacco cessation, particularly the feasibility of delivering the intervention, recruitment, randomisation and retention, as well as measures for data collection in a full trial, will be demonstrated through analysis of trial data, as well as preliminary process evaluation and economic assessments | — |
Secondary
| Measure | Time frame |
|---|---|
