Evaluation of the effects of oral nicotine substitutes (1.5mg lozenge) on the craving in moderate smokers placed in non-smoking situations. A randomized, double-blind, placebo-controlled parallel groups trial.
This research is investigating whether a specific nicotine lozenge, which contains 1.5mg of nicotine, can help people who smoke moderately to control their urge to smoke when they are in places where smoking isn't allowed. The lozenge is flavoured with fresh mint and sweetened. This is a special type of study called a 'randomised, double-blind, placebo-controlled trial'. This means some participants will get the actual nicotine lozenge, and others will get a 'dummy' lozenge (a placebo) that looks and tastes the same but has no active ingredients. Neither the participants nor the doctors will know who is getting what until after the study is over. The main goal is to see how much the lozenge helps reduce the urge to smoke after 30 minutes, and even sooner.
At a glance
What is this study about?
This study is designed to find out if a particular nicotine lozenge can help people who usually smoke to manage their cravings when they are in situations where they can't smoke. It's a key step in helping people who want to quit smoking altogether.
The lozenge being tested contains 1.5 milligrams of nicotine and has a fresh mint flavour. It's being compared against a 'dummy' lozenge, also known as a placebo, which looks and tastes the same but doesn't have any nicotine. This comparison is really important because it helps researchers understand if any improvements are genuinely due to the nicotine in the lozenge, or if they might be due to other factors, like the expectation of feeling better.
Researchers will be carefully tracking how much the urge to smoke changes after using the lozenge. They'll also be looking at how people feel overall during the day, any nicotine withdrawal symptoms, and checking for any side effects. This detailed approach helps them see a full picture of how the lozenge might help people on their journey to stop smoking.
Key takeaways
- This study tests a 1.5mg nicotine lozenge for reducing smoking urges.
- It's for people who smoke moderately and want to control cravings in non-smoking places.
- Participants will receive either the real lozenge or a dummy one, without knowing which.
- Researchers will measure changes in smoking urges and any withdrawal symptoms.
- The study also tracks how many lozenges are used and any side effects.
Who may be eligible?
This study is looking for adults aged 18 and over, and anyone can take part, regardless of whether they are male or female. You would be considered if you currently smoke, but in moderation, and haven't fully stopped yet.
Specifically, you need to be someone who usually smokes but is looking for ways to stop or cut down. The study team will check your smoking habits to make sure you're a good fit for this particular trial.
Could this study suit you?
Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.
- Are you 18 years old or older?
- Do you currently smoke, but not excessively?
- Are you interested in finding ways to manage your urge to smoke?
- Are you comfortable not knowing whether you're taking a real medicine or a dummy one during the study?
What does participation involve?
If you join this study, you would be asked to use either the nicotine lozenge or a dummy lozenge when you find yourself in a non-smoking situation and feel an urge to smoke. You wouldn't know which one you're getting, and neither would the doctors. You would then answer questions about your urge to smoke using a special questionnaire at different times, including shortly after taking the lozenge (at 30, 45, 60, and 90 minutes).
Throughout the study, you'd also be asked to rate your overall craving for smoking during the day and keep track of how many lozenges you use. At the end of the first day, your nicotine withdrawal symptoms would be checked. The total length of your participation would be for a short period, and the study team would monitor any changes in your health and wellbeing carefully.

Common questions
What is a 'dummy' lozenge?
A 'dummy' lozenge, also called a placebo, looks and tastes exactly like the active nicotine lozenge but doesn't contain any medicine. It helps researchers compare the real effect of the nicotine.
Why don't I know if I'm getting the real lozenge or the dummy one?
This is a 'blinded' study. It helps make the results fairer by ensuring that neither you nor the doctors involved have any expectations that might accidentally influence how your cravings are reported or measured. Everyone gets the same experience.
What is 'moderate smoking'?
The study team will define 'moderate smoking' for this trial, but generally, it refers to regular smokers who are not extremely heavy smokers. They will talk to you about your smoking habits to see if you fit.
Will this study help me quit smoking completely?
This study focuses on managing cravings in non-smoking situations. While it could be a step towards quitting, the main goal is to evaluate the lozenge's effect on urges, not necessarily a full cessation program.
What happens if I experience side effects?
The research team will carefully monitor you for any side effects. If you experience anything unusual, you should tell the study team immediately so they can assess it and provide advice.
