ClinConnect Summary

This clinical trial, called "Quit to Win" 2025, is exploring whether a chatbot—an online program that can chat with you—can help people quit smoking. The researchers want to find out if using this chatbot for support can help smokers stop smoking more effectively than just getting standard advice from a healthcare provider. They will compare the success of participants who use the chatbot with those who receive usual care to see which method is more effective in helping people quit smoking.

To participate in this trial, you need to be a resident of Hong Kong, at least 18 years old, and currently smoke daily. You'll also need to be able to communicate in Chinese and use messaging apps like WhatsApp or WeChat. If you join the study, you'll receive personalized advice, a referral for further support, and access to the chatbot that provides counseling. This trial is not yet recruiting participants, but it aims to understand how helpful this new technology can be for smokers looking to quit.
