Abstract
Midwakh, which originated in the Middle East, has started to spread globally with different brands commercialized online and in local stores across Europe and the USA. Dokha is the tobacco used in midwakh. To this day, risk of midwakh smoking is poorly understood. Three different types of dokha were evaluated in this study, classified as cold, medium, and hot using gas chromatography-mass spectrometry (GC-MS). The concentrations of nicotine and polycyclic aromatic hydrocarbons (PAHs) in raw and smoked dokha samples were measured, and the results were compared to data in the literature on different types of tobacco products. PAH concentrations were used to estimate the toxic equivalency quotient, daily exposures, incremental lifetime cancer risk, and hazard quotient. The level of nicotine in raw dokha exceeded by far the levels reported in cigarettes, cigar, waterpipe, and chewing tobacco. Although only a portion of the nicotine is released into the smoke, the amount of nicotine in dokha smoke exceeded those reported for cigarettes. Two PAHs were found in raw dokha at trace amounts and 12 PAHs were detected in dokha smoke in amounts that exceeded those reported for cigarette smoke. The PAHs distribution showed a specific pattern in the smoke and a higher risk factor than that obtained for cigarettes and other tobacco products. Dokha products present a potential higher risk and immediate action should be taken to avoid its global consumption.

Multivariate Analysis of the Predicted Probability of Smoking Behavior of Foster Care Minors: Results of a Study from Romania. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19031173. [PMID: 35162196 PMCID: PMC8834987 DOI: 10.3390/ijerph19031173] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/08/2021] [Revised: 01/14/2022] [Accepted: 01/16/2022] [Indexed: 01/27/2023]
Abstract
Background: There are a multitude of factors that influence smoking status, and minors from the social protection system are a vulnerable category in terms of smoking. Methods: The objective of this research was to assess the degree of smoking dependence and to identify potential predictors of smoking status in foster care teenagers. Smoker status was confirmed by dosing CO in the exhaled air, and the degree of dependence was assessed using the Fagerström score. We performed a multivariate logistic regression analysis. Results: From the 275 foster care minors, 22.5% were current smokers. Exhaled CO was not influenced by general demographic factors, was associated with the frequency of smoking, and was positively correlated with the estimated number of cigarettes consumed daily and with the Fagerström score. The calculated probability of being a smoker was less than 20.4% in 75% of nonsmokers, whereas 75% of actual smokers had a predicted probability higher than 30.3%. Conclusions: In addition to age, gender, social environment, previous exposure to secondhand smoking, and residential type of foster care system, the expressed opinions regarding the health effects of tobacco use were associated with smoking in foster care teenagers.

Nakkash RT, El Boukhari N, Afifi RA. 'When I smoked it, it was like a slap in the face but it felt really good': exploring determinants of midwakh use among young adults in Lebanon. Tob Control 2021; 30:351-355. [PMID: 32269174 DOI: 10.1136/tobaccocontrol-2019-055529] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2019] [Revised: 03/05/2020] [Accepted: 03/10/2020] [Indexed: 11/04/2022]
Abstract
BACKGROUND Dokha ('dizziness' in English) is a type of alternative tobacco product (ATP) increasing in popularity in the Arab world; and smoked in a pipe called a midwakh. Midwakh use is common among nationals in the United Arab Emirates (UAE); yet, evidence indicates its spread among expats in the UAE as well as beyond the UAE. Research on midwakh use is nascent, and no qualitative research has been published. This paper explored the context and determinants of midwakh use among young adults in Lebanon using qualitative methods. METHODS We conducted four focus group discussions with 18 midwakh ever smokers aged 18-25 years in Lebanon. Discussions were recorded, transcribed and thematically analysed using the Pragmatics, Attraction, Communication, Expectations framework. RESULTS 'Pragmatics' was evident in participants' comments about availability of a supply of dokha. For 'attraction', participants described why they prefer midwakh smoking and compared it to other ATPs. Regarding communication, participants shared terms used to describe their use of midwakh (eg, 'buzz'/taking a hit). Participants also described expectations from smoking midwakh, including stress relief. CONCLUSION Midwakh smoking is appealing to young adults due to factors such as the 'buzz', perceived harm reduction, stress relief and its ability to satisfy nicotine craving with small amounts of tobacco. As a result, despite experiencing negative effects on first use, young adults choose to continue to use midwakh, and find it hard to quit. These results have implications for prevention and control of midwakh smoking among young adults. Framework Convention on Tobacco Control guidance documents to address ATPs are critically needed to prevent the global spread of yet another tobacco product.

Almogbel F, Almuqbil S, Rabbani U, Almogbel Y. Prevalence and predictors of midwakh smoking among male students of Qassim University, Al-Qassim, Saudi Arabia. Tob Induc Dis 2020; 18:73. [PMID: 33408598 PMCID: PMC7780927 DOI: 10.18332/tid/125725] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2020] [Revised: 07/18/2020] [Accepted: 07/24/2020] [Indexed: 11/30/2022] Open
Abstract
INTRODUCTION Novel tobacco products are becoming more popular in the Middle East and especially in Saudi Arabia. We studied the prevalence of midwakh pipe (tobacco smoking pipe) use among students at Qassim University and evaluated factors associated with midwakh pipe usage. METHODS A cross-sectional study was conducted using a self-administered questionnaire to collect the data. The participants were male students from Qassim University, Al-Qassim, Saudi Arabia. Data were collected over the period from May to June 2018. A multivariable logistic regression model was used to identify sociodemographic factors and smoking history related to midwakh smoking. RESULTS A total of 316 responses were collected; 7.9% (n=25) were midwakh smokers at some point, and 3.8% (n=12) were current midwakh smokers. Multivariable logistic regression indicated that the significant predictors of midwakh smoking among male university students were having a friend who is a tobacco or midwakh smoker, and consuming other forms of tobacco other than midwakh. CONCLUSIONS Having midwakh smoking friends, having friends smoking any other form of tobacco, and being a smoker could predict the use of midwakh among university male students in Saudi Arabia. Interventions are required to control this behavior to prevent smoking-related health consequences.

Inflammatory biomarkers and growth factors in saliva and gingival crevicular fluid of e-cigarette users, cigarette smokers, and dual smokers: A pilot study. J Periodontol 2020; 91:1274-1283. [PMID: 32052441 DOI: 10.1002/jper.19-0457] [Citation(s) in RCA: 18] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2019] [Revised: 01/26/2020] [Accepted: 01/26/2020] [Indexed: 12/17/2022]
Abstract
BACKGROUND Cigarette smoking remains one of the leading public health threats worldwide. Electronic cigarettes (e-cigs) provide an alternative to conventional cigarette smoking; however, the evidence base of risks and benefits of e-cig use is new and growing. In this cross-sectional pilot study, the effect of e-cig use on biological profiles in saliva and gingival crevicular fluid (GCF) was assessed and compared with the profiles of cigarette smokers (CS), dual users, and non-users. The systemic inflammatory mediators between e-cig users (EC) and these other groups were also assessed. METHODS This pilot cross-sectional study recruited volunteer participants consisting of four groups, non-smokers (NS), CS, EC, and dual EC and cigarette smokers (DS). Saliva and GCF samples were collected and analyzed for biomarkers of inflammation, oxidative stress, anti-inflammatory lipid mediators, tissue injury and repair, and growth factors with immunoassay (enzyme-linked immunosorbent assay and Luminex). RESULTS Smoking status was confirmed via salivary cotinine. Prostaglandin E2 level was significantly increased in CS compared with EC and DS, but not significantly different in EC and DS groups compared with non-smokers (NS). Statistically significant differences were observed between groups of EC and NS (myeloperoxidase [MPO], matrix metalloproteinase-9) as well as between DS and EC for biomarkers of inflammatory mediators (receptor for advanced glycation end products [RAGE], MPO, uteroglobin/CC-10); between groups of DS and NS for extracellular newly identified RAGE binding protein and between CS and NS for MPO. No statistically significant differences in biomarkers of immunity (S100A8, S100A9, galectin-3), tissue injury and repair (Serpine1/PAI-1) and growth factors (brain-derived neurotrophic factor, fibroblast growth factors, platelet-derived growth factor-AA, vascular endothelial growth factor, and others) were found between any of groups. CONCLUSION Statistically significant differences in measurable health outcomes were found between different smoking status groups, suggesting that smoking/vaping produces differential effects on oral health.

Dorey A, Scheerlinck P, Nguyen H, Albertson T. Acute and Chronic Carbon Monoxide Toxicity from Tobacco Smoking. Mil Med 2019; 185:e61-e67. [DOI: 10.1093/milmed/usz280] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2019] [Revised: 07/18/2019] [Indexed: 12/12/2022] Open
Abstract
ABSTRACT
Introduction: Carbon monoxide (CO) is produced from incomplete combustion of hydrocarbons and is a by-product of tobacco smoking. Chronic cigarette smokers often have carboxyhemoglobin (COHb) concentrations as high as 10%. We report a case of severely elevated COHb and polycythemia because of tobacco smoking and provide a review of the literature regarding elevated COHb in smokers. Materials and Methods: A comprehensive search of PubMed and Google Scholar was performed looking for articles on tobacco smoking and CO, COHb, CO poisoning, cigarettes, pipes, cigars and water pipes/hookah smokers. Result: COHb levels in frequent cigarette smokers generally range from 4.2% presmoking to 8.6% postsmoking. A heavy cigarette smoker presented twice with symptoms of CO toxicity and was found to have levels 21.8 to 24.2%. Cigar smokers have been found to have COHb ranging as high as 13.0 to 38.6% in case reports. Waterpipe or “hookah” smokers generally have COHb levels 10.1% +/−2.5% and case reports, and series of even higher levels associated with CO toxicity symptoms are common. Waterpipe smokers have been found to have COHb levels as high as 39.2% after smoking. Conclusions: Many active duty military and military veterans are tobacco smokers and these patients and their health care providers should be aware of the adverse effects of CO toxicity from tobacco smoking. Patients may have symptoms such as headaches, syncope, and ataxia in the setting of acute CO toxicity; however, the chronic effects of CO may not be completely understood. Future work could explore chronic CO toxicity and its effects on strength and exercise tolerance in military personnel and provide education to service members, veterans, and health care providers.
