About

The investigators will conduct a message-exposure experiment with nationally representative samples of smokers, dual-users (cigarettes and e-cigarettes), and young adult non-smokers (aged 18-29).

Experimental messages will address the reduction of nicotine in cigarettes. Participants will also complete a follow-up survey after 2 weeks, measuring their recall of the messages and behaviors since message exposure.

Full description

A national probability-based sample will be recruited to include 900 current exclusive smokers, 450 dual users, and 450 young adult (18-29) non-smokers, evenly split between men and women.

The study will be conducted using a self-administered, online questionnaire via proprietary, web-assisted interviewing software.

Participants are randomized to one of four conditions:

• reduced nicotine messages
• modified risk messages
• a combination of reduced nicotine message and modified risk message
• control messages with no cigarette-related content

Participants will take part in two sessions: in session 1 (estimated at about 15 min) participants will see the messages and report immediate outcomes including risk perceptions.

In session 2, which will take place 2 weeks after session 1, participants will complete a brief 5-minute survey measuring their recall of the messages and behaviors since message exposure.
