Background: Cigarette smoking is the major cause of chronic obstructive pulmonary disease, but studies on the contribution of other smoking techniques are sparse.

Objective: To determine whether pipe and cigar smoking was associated with elevated cotinine levels, decrements in lung function, and increased odds of airflow obstruction.

Design: Cross-sectional study.

Setting: Population-based sample from 6 U.S. communities.

Participants: Men and women aged 48 to 90 years without clinical cardiovascular disease at enrollment who were part of MESA (Multi-Ethnic Study of Atherosclerosis).

Measurements: The MESA Lung Study measured spirometry according to American Thoracic Society guidelines and urine cotinine levels by immunoassay on a subsample of MESA. Pipe-years and cigar-years were calculated as years from self-reported age of starting to age of quitting (or to current age in current users) multiplied by pipe-bowls or cigars per day.

Results: Of 3528 participants, 9% reported pipe smoking (median, 15 pipe-years), 11% reported cigar smoking (median, 6 cigar-years), and 52% reported cigarette smoking (median, 18 pack-years). Self-reported current pipe and cigar smokers had elevated urine cotinine levels compared with never-smokers. Pipe-years were associated with decrements in FEV1, and cigar-years were associated with decrements in the FEV1–FVC ratio. Participants who smoked pipes or cigars had increased odds of airflow obstruction whether they had also smoked cigarettes (odds ratio, 3.43 [95% CI, 1.75 to 6.71]; P < 0.001) or not (odds ratio, 2.31 [CI, 1.04 to 5.11]; P = 0.039) compared with participants with no smoking history.

Limitation: Cross-sectional design.

Conclusion: Pipe and cigar smoking increased urine cotinine levels and was associated with decreased lung function and increased odds of airflow obstruction, even in participants who had never smoked cigarettes.

Lines represent the median cotinine values (log scale). Upper and lower horizontal bars represent maximum and minimum values, excluding outliers. Box height represents the interquartile range. Box width is proportional to sample size. Circles represent outlier values. P < 0.001 for all smoking techniques versus never-smokers. Never-smokers (n = 1620) reported smoking fewer than 100 cigarettes, fewer than 20 pipe-bowls, and fewer than 20 cigars in life. Cigar smokers (n = 47) reported current cigar use but no current pipe or cigarette smoking. Pipe smokers (n = 6) reported current pipe use but no current cigarette smoking. Cigarette smokers (n = 330) reported current cigarette smoking.

The article does not separate the pipe & cigar smokers who inhale versus those that do not. Prior publications have shown different risks for lung cancer in pipe smokers who inhale compared to those who do not. Did you obtain this data?
