CO exposure, puff topography, and subjective effects in waterpipe tobacco smokers.

ABSTRACT:

Introduction

Waterpipe tobacco smoking is increasing in popularity though the toxicant exposure and effects associated with this tobacco use method are not well understood.

Methods

Sixty-one waterpipe tobacco smokers (56 males; mean age +/- SD, 30.9 +/- 9.5 years; mean number of weekly waterpipe smoking episodes, 7.8 +/- 5.7; mean duration of waterpipe smoking 8.5 +/- 6.1 years) abstained from smoking for at least 24 hr and then smoked tobacco from a waterpipe ad libitum in a laboratory. Before and after smoking, expired-air carbon monoxide (CO) and subjective effects were assessed; puff topography was measured during smoking.

Results

The mean waterpipe use episode duration was 33.1 +/- 13.1 min. Expired-air CO increased significantly from a mean of 4.0 +/- 1.7 before
