Summary

The goal of this trial is to assess the feasibility, acceptability, and preliminary effectiveness of chewing gum to reduce cigarette consumption and promote smoking cessation. The main questions it aims to answer are: Do participants in the intervention group report a higher reduction in cigarette consumption, improved smoking cessation outcomes, and healthier oral health than the control group? Researchers will compare chewing gum intervention to unassisted quitting to see if chewing gum works to cigarette reduction and smoking cessation. Participants will: 1. Receive very brief smoking cessation advice and booklet at baseline. 2. Take chewing gum or unassisted quitting for 1 week.
