Use of Nicotine Replacement Therapy (NRT) Sample and Brief Smoking Cessation Advice for Recruiting Smokers
Hong Kong834 participantsStarted 2018-10-13
Plain-language summary
Background More than 60% of the daily smokers in Hong Kong have never tried and have no intention to quit smoking. About 30.8% of daily smokers attempted to quit but failed. Nicotine replacement therapy (NRT) is a safe and effective pharmacotherapy to reduce withdrawal symptoms during early stage of tobacco abstinence and increase quit rate. However, the prevalence of using NRT in Hong Kong is lower than most of the developed countries. The proposed project aims to test if providing free NRT sampling to smokers can increase quit attempt, the use of smoking cessation (SC) services and abstinence.
Methods University undergraduate students will be trained, and will invite smokers at outdoor smoking hotspots to quit smoking and enroll into SC services. Eligible smokers will be randomized to experimental or control group according to a cluster randomization, using recruitment session as the randomization unit. The experimental group will be provided with 1-week free NRT sampling and medication counselling, whereas the control group will be provided medication counselling. Both groups are advised to enroll in the SC services. The primary outcome is the proportion of smokers who report quit attempts at 1 month follow-up
Discussions The findings will inform the feasibility and effectiveness of delivering free NRT sampling to increase quit attempt, the use of smoking cessation services and abstinence. It will yield more information on smokers' adherence to the NRT sampling, side effect and safety issue of the usage.

Inclusion Criteria:
* Hong Kong residents
* aged 18 to 65 years
* have used any tobacco products in the past month
* able to read and speak Chinese
* have not used NRT for the past month
Exclusion Criteria:
* Have severe angina, serious cardiac arrhythmias and hypertension
* Have suffered from acute myocardial event in the past 4 weeks
* Pregnant nor breastfeeding
* Under medication and treatment due to mental illness
One of the inclusion criteria was "smoke 10 cigarettes or more per day in the past week" and is amended to "have used any tobacco products in the past month". The initial intention of setting the inclusion criteria of at least 10 cigarettes per day (CPD) is to recruit smokers who have moderate to strong level of craving and a greater need for NRT. However, we also recognize that one of the objectives of the research is to promote the use of NRT for quit attempts with NRT sampling. In fact, smokers who smoke less than 10 CPD can also benefit from using NRT gums. Therefore, the change in the inclusion criteria does not deviate from our research aim. In contrast, with the removal of the criterion for CPD, we will be able to reach out to a larger group of smoking population and encourage more smokers to use NRT to quit smoking
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
