Trial Summary

Will I have to stop taking my current medications?

If you are using nicotine replacement, varenicline, or bupropion (only for smoking cessation), you will need to stop taking them to participate in the trial. If you are taking bupropion for other reasons, like depression, you cannot join the trial.

What data supports the effectiveness of the treatment Nicotine Pouches + Lozenges for Smoking Cessation?

Research indicates that medicinal nicotine products, like lozenges, have been used successfully to help people quit smoking. Nicotine pouches, such as Zyn, are considered a low-risk alternative to cigarettes and may serve as a novel approach to nicotine replacement therapy.12345

Is the combination of nicotine pouches and lozenges safe for human use?

Research suggests that nicotine pouches, like ZYN, may be a lower-risk alternative to traditional tobacco products, but specific safety data for the combination of nicotine pouches and lozenges is not available. Nicotine lozenges have been used as a smoking cessation aid, and while they may have a low risk of abuse, especially among younger individuals, their safety profile is generally considered acceptable for smoking cessation.14678

How is the treatment with nicotine pouches and lozenges different from other smoking cessation options?

This treatment is unique because it uses tobacco-free nicotine pouches, which are placed between the lip and gum, offering a low-risk alternative to traditional tobacco products. Unlike other nicotine replacement therapies, these pouches come in various flavors and are marketed as a novel, discreet way to deliver nicotine without tobacco.19101112

What is the purpose of this trial?

The goal of this clinical trial is to investigate how well nicotine pouches and nicotine mini lozenges serve as substitutes for cigarettes when people try to switch from smoking to using these alternate nicotine products.Participants will:* Use nicotine pouches, nicotine mini lozenges, or no study product for a week and then try not to smoke for 3 weeks.* Have 6 in-person research visits and 1 follow-up call* Complete questionnaires at each study contact and use a smartphone app to record smoking and study product use

Findings from Research

ZYN nicotine pouches contain no nitrosamines or polycyclic aromatic hydrocarbons (PAHs), indicating a potentially lower risk profile compared to traditional tobacco products, which often contain harmful constituents.
The levels of harmful and potentially harmful constituents (HPHCs) in ZYN were found to be similar to those in nicotine replacement therapy (NRT) products, suggesting that ZYN may be a safer alternative for nicotine delivery compared to moist snuff, which had significantly higher levels of harmful compounds.

In a study involving 63 smokers, both snus and Zonnic were preferred over nicotine gum, showing greater effectiveness in reducing smoking urges and causing fewer side effects.
Participants experienced significant reductions in smoking (33% for gum, 37% for snus, and 42% for Zonnic), indicating that snus and Zonnic could be promising alternatives for nicotine replacement therapy, warranting further research on their long-term effectiveness.

A study analyzing nicotine pouch advertising from January 2019 to September 2021 found that Zyn and Velo dominated the market, accounting for 44.4% and 52.8% of 286 unique ads, respectively, with a total expenditure of nearly $24.8 million, primarily on radio and television.
The advertising themes heavily emphasized 'freedom' and 'flavour', with Zyn focusing on brand identity and Velo on innovation, highlighting the need for regulatory oversight to understand the impact of these marketing strategies on consumers, especially young people.
