Summary
This study looked at how the size of a waterpipe (small, medium, or large) changes how people smoke and what chemicals they are exposed to. Forty young adult regular waterpipe smokers each smoked from all three sizes in separate lab visits. Researchers measured puffing patterns, nicotine in saliva, carbon monoxide in breath, and how satisfying or harmful the experience felt. The goal was to see if waterpipe size affects smoking behavior and toxicant exposure.
