Investigation of the relation between carbon monoxide exposure/intoxication and tobacco-free narghile products

Objectives: Use of tobacco-based narghiles may have potentially fatal consequences, such as carbon monoxide (CO) intoxication. However, there are only limited studies on the effects on human health and CO levels of tobacco-free narghile products. The primary aim of this study was to investigate the...

Description
Summary:Objectives: Use of tobacco-based narghiles may have potentially fatal consequences, such as carbon monoxide (CO) intoxication. However, there are only limited studies on the effects on human health and CO levels of tobacco-free narghile products. The primary aim of this study was to investigate the effect of tobacco-free narghile consumption on carboxyhemoglobin (COHb) levels and whether this would cause CO intoxication in active and passive narghile users.Design: Observational study. Methods: Four hundred ninety-nine individuals exposed to tobacco-free narghile smoke were divided into four groups; Group I: active narghile smokers, and non-cigarette smokers, Group II: active narghile smokers and active cigarette smokers, Group III: passive narghile smokers and non-cigarette smokers and Group IV: passive narghile smokers and active cigarette smokers. Fifty-nine healthy volunteers were enrolled as control groups (Group V, non-cigarette smoker controls, and Group VI, cigarette smoker controls). COHb levels were compared among the groups. Results: Mean pre-exposure % COHb levels for groups I-IV were 2.61+-1.46, 3.00+-1.37, 2.09+-1.45 and 3.00+-2.13, and post-exposure % COHb levels for groups were 3.45+-1.92, 4.17+-2.01, 2.60+-1.66 and 4.50+-2.32, respectively. Control groups (V-VI) % COHb levels were 0.90+-0.82 and 1.60+-0.85, respectively. COHb levels rose significantly after exposure to tobacco-free narghile smoke in all groups (p
