Communicating Waterpipe Tobacco Harms to Reduce Use Among Young Adults: A Study of Hookah Café Customers in the Atlanta Area

Wake Forest University Health Sciences·interventional·Posted Jun 23, 2023·Updated Feb 2, 2026

In Brief

A clinical study evaluating Health Warnings and No Warnings for Waterpipe Tobacco Smoking. Completed, enrolled 977 participants across 1 site.

Detailed Summary

The purpose of the study is to assess the effectiveness of health warnings on waterpipe smoking behavior in a real-world setting. The primary hypothesis is that hookah café customers who are in the intervention (warning) arm will smoke less than customers who are in the control (no warning) arm, determined by differences in the boost in expired carbon monoxide from café entry to after café exit.
