Pakistan is one of the most vulnerable low- and middle-income countries with 29 million adult active tobacco users. Smoking cessation services are lacking as the tobacco control initiatives have largely failed to address the smoking endemic. Over the last five years, Pakistan has witnessed the use of innovative tobacco harm reduction such as e-cigarettes, nicotine pouches, and non-nicotine replacement therapies (non-NRTs). However, their use remains limited. THR products are imported legally as consumer goods and are taxable. The lack of sufficient data for THR and its application is a challenge in gauging their effectiveness in assisting smokers to quit combustible smoking. Evidence-based studies on e-cigarettes and other nicotine products are required to gauge the effectiveness of e-cigarettes and nicotine pouches as smoking cessation aids. Keeping in view the study objectives, a sample size of 600 participants will be sufficient to assess the effectiveness of e-cigarettes and nicotine pouches for smoking cessation in Pakistan. Of these, 200 participants each will receive e-cigarettes and nicotine pouches along with basic care counseling, while the remaining 200 participants will only receive basic care counseling for 48 weeks. The association of participants' characteristics with smoking and health status will be based on bivariate and multivariate analysis. The simple t-test and variance analysis will assess the differences in intervention indicators between the control and treatment groups. For the inferential analysis, the average treatment impact of the treatments will find using quasi-experimental techniques such as difference in difference (DID) or Propensity Score Matching (PMS). This study will be evaluated participants at baseline, after their self-decided "quit date,". The follow-up will be a survey every 12 weeks. Results may inform the public, decision-makers, and researchers about the use of e-cigarettes and nicotine pouches helping smokers to quit smoking or switch to less harmful alternatives in the short- and medium-term periods.

The four basic care counseling sessions will be held over the course of 48 weeks with the supply of e-cigarettes and liquid. Every 12 weeks, a standard care counseling session will be offered, and it will be followed by a study visit to track any alterations in the user's physical or mental health as well as any side effects from using e-cigarettes.

Number of participants reported adverse events of e-cigarettes or nicotine pouches
The primary outcome will be a long-term change in health status. The best proxy indication for demonstrating a change in tobacco smoking, which is adequate to result in a clinically relevant long-term health benefit, is unknown. In the absence of accurate health indicators, we will use the change in smoking rate from baseline and smoking cessation as primary outcomes.
Time frame: 60 Weeks
Change in the number of combustible cigarettes per day
This study will evaluate the impact of e-cigarettes and nicotine pouches on cigarettes per day (CPD) and smoking cessation (7 Day Point Abstinence) at weeks 24 and 48.
Time frame: 60 Weeks
Point-prevalence abstinence
Self-reported point-prevalence abstinence in the previous week with biochemical validation will be used exhaled carbon monoxide less than 10 parts per million (PPM).
Time frame: 60 Weeks
7-day point-prevalence abstinence and harm reduction
Secondary outcomes will include 7-day point-prevalence abstinence (at all subsequent check-ups) (biochemically validated at weeks 12, 24, 36, 48, and 60). As a secondary goal, this study will analyze the harm-reduction effect of e-cigarettes and nicotine pouches, as well as the analysis of adverse events.
Time frame: 60 Weeks
