Interventions

Reduced nicotine message exposurebehavioral

Participants will be shown two messages about harms of reduced nicotine cigarettes. The two messages will be drawn from a pool of five messages. The messages will communicate that reduced nicotine cigarettes will still have the rest of the harmful chemicals and cause diseases as the regular cigarettes, but they would make it easier to quit.

Modified risk message exposurebehavioral

Participants will be shown two messages about electronic cigarettes as an alternative to regular cigarettes. The two messages will be drawn from a pool of five messages. The messages will communicate that electronic cigarettes are less likely than regular cigarettes to cause severe diseases such as lung cancer.

Combined message exposure (reduced nicotine + modified risk)behavioral

Participants will be shown two messages, one from the reduced nicotine message set and one modified risk message set.

Control message exposurebehavioral

Participants will be shown two messages about drinking bottled water. These will be selected from a pool of five message. The messages display specific water products and describe hydration as a healthy activity.
