ClinConnect Summary

This clinical trial is looking into whether chewing gum can help people cut down on smoking or quit altogether. The researchers want to find out if people who chew gum report smoking fewer cigarettes and have better overall oral health compared to those who are trying to quit without any help. Participants in the study will receive some brief advice about quitting smoking and a booklet, and then they will either chew gum or try to quit on their own for one week.

To join this study, you need to be at least 18 years old, live in Hong Kong, and have been smoking at least one cigarette a day for the past three months. You should also be someone who either enjoys chewing gum or is willing to try it, and you need to be able to communicate in Cantonese. If you have communication challenges or are already part of another smoking cessation program, you won’t be eligible. Throughout the trial, you'll have the chance to share your experiences with the researchers through messaging apps like WhatsApp or WeChat.
