Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
This study aims to evaluate both the effectiveness and cost-effectiveness of integrating GHWs with pharmacist-led personalized counseling at primary healthcare pharmacies in Bangladesh and Pakistan. A cluster randomized controlled trial (RCT) will be conducted, enrolling 5,052 adult participants in each country from community pharmacies. Participants will be randomly assigned to one of three groups: (1) GHW-only intervention, (2) combined GHW and pharmacist-led counseling, or (3) standard care (control).
The intervention includes twice-yearly counseling sessions-delivered both in-person and digitally-supported by educational booklets and leaflets. Primary outcomes are smoking cessation rates and blood pressure reduction. Secondary outcomes include improved hypertension and diabetes management, medication adherence, lifestyle modification, reduced hospitalizations and mortality, and incremental cost-effectiveness. Bayesian statistical models will be used to assess efficacy, and economic evaluations will determine the cost-effectiveness of the interventions. The findings aim to inform scalable public health strategies for tobacco control and NCD prevention in resource-limited settings.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
GHW-only intervention
This group will receive only graphical health warnings (GHWs) featuring images proposed by the Bangladesh Tobacco Control Cell, explicitly illustrating smoking-related harms, such as mouth diseases, damaged teeth and gums, lung diseases and cancer, heart diseases and cardiovascular damage, and throat and oral cancer. Additionally, these warnings will clearly highlight the benefits of quitting smoking-including improved overall health, reduced disease risks, financial savings, and enhanced quality of life-as well as practical cessation techniques. Participants will receive these GHW materials at baseline and again at the six-month follow-up to reinforce these critical health messages; however, this intervention group will not receive any counselling services. Monthly SMS reminders will also be sent to participants, prompting them to review the GHW leaflet and reinforcing the negative health impacts of smoking and the benefits of quitting.

GHW plus pharmacist-led counselling
Participants in this group will receive graphical health warnings (GHWs) featuring Bangladesh Tobacco Control Cell-approved images clearly depicting smoking-related harms (e.g., mouth diseases, damaged teeth and gums, lung cancer, heart disease, and oral cancer). Additionally, they will receive personalized counselling from community pharmacists, focused on the specific health and financial benefits of quitting, practical cessation techniques, strategies for overcoming barriers, and relapse prevention. This combined intervention will be provided at baseline and reinforced at a six-month follow-up. Monthly SMS reminders will also be sent, reinforcing key messages on the harmful effects of smoking and benefits of cessation.

Standard care control
Participants in this group will receive only routine pharmacy services based on standard pharmacy practice guidelines applicable in each country. They will not receive any additional graphical health warnings or counselling interventions. Outcomes will be assessed at baseline, 6 months, and 12 months, consistent with the intervention groups.
Routine pharmacy services (no intervention)
Participants in this group will receive only routine pharmacy services based on standard pharmacy practice guidelines applicable in each country. They will not receive any additional graphical health warnings or counselling interventions. Outcomes will be assessed at baseline, 6 months, and 12 months, consistent with the intervention groups.
