What this trial studies

This project tests an integrated intervention designed to help adult daily smokers living with children and non-smoking partners quit smoking. The intervention includes brief cessation advice, Nicotine Replacement Therapy, and instant messaging support, compared to a waitlist control group. The study focuses on families from disadvantaged backgrounds in Hong Kong, aiming to increase smoking cessation rates and reduce children's exposure to secondhand smoke. It also seeks to raise awareness among parents about their children's exposure levels and promote the adoption of this intervention model by local health organizations.
