“…In the case of WP, the literature tried to link the WP with lung cancer about 50 years ago [27] and accumulating evidence, especially from regions where WP is endemic, has linked WP smoking with diseases that are known the be caused by tobacco use [11]. Additionally, recent studies conducted in North America regarding the contents analysis of the products used in WP, the volume and the content of smoke produced in a WP smoking session, and the impact on air quality in places where either tobacco or tobacco-free products were smoked [15,34,5,29]. All provide a strong base for a plausible inference that the chronic use of such products may well have a serious impact on the users health in the future.…”

Knowledge About the Waterpipe (Hookah), a Qualitative Assessment Among Community Workers in a Major Urban Center in Canada

2015

Waterpipe (WP) use has surged in popularity since the introduction of flavoured shisha. It is now an increasingly popular form of smoking among youth in North America. Health professionals/educators knowledge about the WP may well be inadequate. This study, using qualitative methods, sought to explore the knowledge and attitude of leaders in the community toward the WP. Family physicians, pharmacists, tobacco counsellors, social workers and educators were invited to participate in a one-one interview using open-ended questions. A total of 27 interviews were conducted. Individuals from Eastern Mediterranean backgrounds raised doubt about the overemphasised cultural significance of the WP and perceived this as a marketing strategy by industry. Most felt that WP smokers believed the WP to be less harmful than cigarettes and that the use of flavoured tobacco was motivating people to smoke. Participants believed that education should be directed at the general public and healthcare professionals, suggesting school programs and the use of social media to inform young smokers. Most thought that the current practices regarding packaging and second hand smoke exposure are confusing. They identified the lack of knowledge, poor enforcement procedures, "so called cultural aspects" and the economic impact of banning the WP on small businesses as barriers to change. Despite the awareness of an increase in WP use, our participants recognized that little has been done to curb this problem. Our findings emphasize the need for further education and better legislation to regulate WP use and availability.

“…The ongoing study and the Blank et al study involved two 2-hour sessions in which current waterpipe users smoked active or placebo waterpipe tobacco. In the latter study,14 waterpipe users who also smoked at least five cigarettes per day participated in two 2-hour sessions that involved either cigarette or waterpipe smoking. Only the data from active waterpipe conditions were included in this analysis.…”

Waterpipe tobacco products: nicotine labelling versus nicotine delivery

2011

Background Waterpipe tobacco package labelling typically indicates “0.0% tar” and “0.05% or 0.5% nicotine”. Objective To determine the extent to which nicotine labeling is related to nicotine delivery. Methods 110 waterpipe smokers engaged in a 45-minute waterpipe smoking session. Puff topography and plasma nicotine were measured. Three waterpipe tobacco brands were used: Nakhla (0.5% nicotine), Starbuzz (0.05% nicotine), and Al Fakher (0.05% nicotine). Data were analyzed by one-way ANOVA. Results Topography did not differ across brands. Peak plasma nicotine varied significantly across brands. Al Fakher had the highest nicotine delivery (11.4 ng/ml) followed by Nakhla (9.8 ng/ml) and Starbuzz (5.8 ng/ml). Conclusions Nicotine labelling on waterpipe tobacco products does not reflect delivery; smoking a brand with a “0.05% nicotine” label led to greater plasma nicotine levels than smoking a brand with a “0.5% nicotine” label. Waterpipe tobacco products should be labelled in a manner that does not mislead consumers.

“…10,[25][26][27][28][29][30][31] An example of an acute effect is that a single 30-min session of narghile smoking (10 g of double apple-flavored tabamel) by 45 volunteers induced a significant increase in SBP (from 120 Ϯ 12 to 132 Ϯ 18 mm Hg), DBP (from 75 Ϯ 8 to 83 Ϯ 13 mm Hg), and heart rate (from 80 Ϯ 10 to 96 Ϯ 17 beats/min). 31 An example of a chronic effect is that the resting heart rate and resting SBP of the 22 ENS with a Ͼ 5 narghile-year history were significantly higher than those of the HNS group (93 Ϯ 4 vs 78 Ϯ 4 beats/min and 141 Ϯ 4 vs 131 Ϯ 3 mm Hg, respectively).…”

“…In addition, studies have demonstrated acute (immediate) effects of narghile smoke in the form of increased heart rate, breathing frequency, expired carbon monoxide, SBP, or DBP and a decline in lung function. [25][26][27][28][29][30][31] However, most of these studies have evaluated only changes in basic spirometric and/or cardiac measures at rest.…”

Investigation of Exclusive Narghile Smokers: Deficiency and Incapacity Measured by Spirometry and 6-Minute Walk Test

et al. 2014

BACKGROUND: Studies on the submaximal aerobic capacity of exclusive narghile smokers (ENS) seem necessary in view of effective prevention of cardiorespiratory diseases. The goal of the study was to assess, by 6-min walk test (6MWT) data, the submaximal aerobic capacity of ENS, to identify factors influencing their 6-min walk distance (6MWD), and to compare their data with those of a healthy non-smoker (HNS) group. METHODS: Seventy 20 -60-y-old male ENS were included. Narghile use (narghile-years) and anthropometric, clinical, spirometric, and 6MWT data were collected. Univariate and multivariate analyses were used to identify factors influencing 6MWD. Data of a subgroup of 40 -60-y-old ENS (n ‫؍‬ 25) were compared with those of an age-matched HNS group (n ‫؍‬ 53). RESULTS: The median (first to third quartile) for age and narghile use were 32 (26 -43) and 17 (8 -32) narghile-years, respectively. The profile of ENS performing the 6MWT was as follows: at the end of the 6MWT, 34% and 9% had a low heart rate (< 60% of maximum predicted) and high dyspnea scores (> 5/10, visual analog scale), respectively; 3% had an oxyhemoglobin saturation decrease of > 5 points during the test; and 20% had an abnormal 6MWD (less than the lower limit of the normal range). The factors that significantly influenced the 6MWD, explaining 38% of its variability,
