Effect of cigar smoking on carboxyhaemoglobin and plasma nicotine concentrations in primary pipe and cigar smokers and ex-cigarette smokers.
Five ex-cigarette smokers and five primary pipe and cigar smokers each smoked a large cigar. Carboxyhaemoglobin (COHb) and plasma nicotine levels were measured. In the ex-cigarette smokers mean COHb rose from 2.9% to 9.6% and plasma nicotine from 79.0 nmol/l to 281 nmol/l (12.8-45.6 ng/ml). This response was similar to that of cigarette smokers smoking cigarettes, which indicated that the subje...
متن کاملSecondary Cigar and Pipe Smokers*
This study of 130 subjects was performed to obtain more data about the smoking habits and levels of carboxyhemoglobin in various types of pipe and cigar smokers. These smokers may be divided by history into primary or secondary smokers and also into current inhalers and noninhalers. Prior studies of carboxyhemoglobin levels have yielded conflicting results, presumably due to differences in curr...

متن کاملUrinary nicotine concentrations in cigarette and pipe smokers.
Urinary concentrations of nicotine were studied in men who did not smoke (27) and in men who smoked cigarettes only (145) or pipes only (48). The median urinary nicotine concentrations were less than 50 ng/ml (the detection limit of the assay for urine tests) in the non-smokers, 1393 ng/ml in the cigarette smokers, and 1048 ng/ml in the pipe smokers. These values were standardised for urinary p...
متن کاملCarboxyhaemoglobin levels in water-pipe and cigarette smokers.
UNLABELLED Water-pipe smoking is growing in popularity, especially among young people, because of the social nature of the smoking session and the assumption that the effects are less harmful than those of cigarette smoking. It has however been shown that a single water-pipe smoking session produces a 24-hour urinary cotinine level equivalent to smoking 10 cigarettes per day. AIM We aimed to ...
