Kommunikasjon om nikotinreduksjon i sigaretter

3. november 2026 oppdatert av: Lyudmila Popova, Georgia State University

Kommunikasjon om nikotin og forskjellsrisiko ved tobakksprodukter i prioriterte populasjoner

The goal of this clinical trial is to learn how a messaging campaign about reduced nicotine cigarettes and policy, combined with the use of very low nicotine cigarettes (VLNCs), affects smoking behavior and attitudes among adult smokers. The study also aims to assess the efficacy of the messages in different populations, including smokers with past-month serious psychological distress (SPD), low socioeconomic status (SES), and those in neither category.

The primary hypothesis is: exposure to messages in combination with VLNC use will lead to less cigarettes use compared to VLNCs without messages.

Researchers will compare: The effects of receiving VLNCs with messages (treatment group) to receiving VLNCs without messages (control group).

Participants will: Complete a baseline survey and be randomly assigned to one of two groups: treatment (VLNCs + messages) or control (VLNCs only). Attend weekly study visits for surveys, breath samples, and receive supply of VLNCs , either with or without the messaging campaign. Complete brief daily surveys through text messages.

Detaljert beskrivelse

This is a randomized, open label, controlled, two-site study to test the efficacy of a messaging campaign about reduced nicotine cigarettes and policy in combination with the use of very low nicotine cigarettes (VLNCs). Smokers from three groups: with past-month serious psychological distress (SPD), with low socioeconomic status (SES), and in neither category will complete a 1-week baseline and a 4-week study; they will be randomized to one of two conditions:

  1. treatment condition, where participants receive VLNCs during weekly visits and are exposed to messages about VLNCs and reduced nicotine policy.
  2. control condition, where participants receive VLNCs without exposure to messages.

Message intervention: Messages about VLNCs and reduced nicotine policy will be professionally developed as full-color inserts (small leaflets that will be inserted into cigarette packs given to participants), print ads, and videos. At each weekly visit, participants will see 3-6 messages about VLNCs and reduced nicotine policy (in the treatment condition) or, in the control condition, 3-6 messages unrelated to tobacco (ads for bottled water, which are neutral messages that are unlikely to affect tobacco-related perceptions or behavior). Participants in the treatment conditions will also have inserts in their VLNC cigarette packs.

Baseline visit: Participants will complete a baseline survey, provide expired breath Carbon Monoxide (CO) sample, and receive a 1-week supply of the study cigarettes (full nicotine).

Randomization visit: Participants will be randomized into either the treatment (VLNCs + messages) or control (VLNCs only) condition. Participants will complete questionnaires, provide an expired CO sample, and receive a 14-day supply of VLNCs (either with or without the messages, according to the assigned condition).

Weekly visits: Starting one week after the randomization visit, participants will complete 4 weekly visits at their designated study site. At each visit, they will complete questionnaires, provide an expired CO sample, and receive a 14-day supply of VLNCs (with or without the messages, according to the assigned condition).

Daily logs: Throughout the baseline and 4 weekly study periods, participants will receive daily text messages with links to brief online surveys.

Våpen og intervensjoner

Deltakergruppe / Arm
Intervensjon / Behandling
Eksperimentell: VLNC with message campaign

Participants in this arm will receive VLNCs during weekly visits and be exposed to messaging about VLNCs and reduced nicotine policy through multiple formats, including inserts placed in cigarette packs, printed advertisements, and videos presented during weekly visits.

Participants will be exposed to messaging about VLNCs and reduced nicotine policy through multiple formats, including inserts placed in cigarette packs, printed advertisements, and video materials presented during their weekly visits.

Annen: VLNC only

Participants in this arm will receive VLNCs during weekly visits but will not receive any messaging related to cigarettes or reduced nicotine policy. Instead, they will only be exposed to control messages, such as advertisements for bottled water, during weekly visits.
