Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Young adults, defined as those 18-29 years old, have the highest rates of waterpipe tobacco smoking, which increases their risk of a variety of pulmonary, neurological, and oncological health conditions, among many others. This trial will randomly assign young adult waterpipe users or those susceptible to use to view waterpipe tobacco packages with text warning, pictorial warnings, or no warnings in a one-time online study. Participants will answer a series of questions regarding each package.
