Abstract
We assessed the efficacy of ozonation as an indoor remediation strategy by evaluating how a carpet serves as a sink and long-term source of thirdhand tobacco smoke (THS) while protecting contaminants absorbed in deep reservoirs by scavenging ozone. Specimens from unused carpet that was exposed to smoke in the lab ("fresh THS") and contaminated carpets retrieved from smokers' homes ("aged THS") were treated with 1000 ppb ozone in bench-scale tests. Nicotine was partially removed from fresh THS specimens by volatilization and oxidation, but it was not significantly eliminated from aged THS samples. By contrast, most of the 24 polycyclic aromatic hydrocarbons detected in both samples were partially removed by ozone. One of the home-aged carpets was installed in an 18 m3 room-sized chamber, where its nicotine emission rate was 950 ng day-1 m-2. In a typical home, such daily emissions could amount to a non-negligible fraction of the nicotine released by smoking one cigarette. The operation of a commercial ozone generator for a total duration of 156 min, reaching concentrations up to 10,000 ppb, did not significantly reduce the carpet nicotine loading (26-122 mg m-2). Ozone reacted primarily with carpet fibers, rather than with THS, leading to short-term emissions of aldehydes and aerosol particles. Hence, by being absorbed deeply into carpet fibers, THS constituents can be partially shielded from ozonation.

Policy-relevant differences between secondhand and thirdhand smoke: strengthening protections from involuntary exposure to tobacco smoke pollutants. Tob Control 2023:tc-2023-057971.

Abstract
Starting in the 1970s, individuals, businesses and the public have increasingly benefited from policies prohibiting smoking indoors, saving thousands of lives and billions of dollars in healthcare expenditures. Smokefree policies to protect against secondhand smoke exposure, however, do not fully protect the public from the persistent and toxic chemical residues from tobacco smoke (also known as thirdhand smoke) that linger in indoor environments for years after smoking stops. Nor do these policies address the economic costs that individuals, businesses and the public bear in their attempts to remediate this toxic residue. We discuss policy-relevant differences between secondhand smoke and thirdhand smoke exposure: persistent pollutant reservoirs, pollutant transport, routes of exposure, the time gap between initial cause and effect, and remediation and disposal. We examine four policy considerations to better protect the public from involuntary exposure to tobacco smoke pollutants from all sources. We call for (a) redefining smokefree as free of tobacco smoke pollutants from secondhand and thirdhand smoke; (b) eliminating exemptions to comprehensive smoking bans; (c) identifying indoor environments with significant thirdhand smoke reservoirs; and (d) remediating thirdhand smoke. We use the case of California as an example of how secondhand smoke-protective laws may be strengthened to encompass thirdhand smoke protections. The health risks and economic costs of thirdhand smoke require that smokefree policies, environmental protections, real estate and rental disclosure policies, tenant protections, and consumer protection laws be strengthened to ensure that the public is fully protected from and informed about the risks of thirdhand smoke exposure.

Weigel EA, Matt GE. When Hotel Guests Complain About Tobacco, Electronic Cigarettes, and Cannabis: Lessons for Implementing Smoking Bans. Tob Use Insights 2022; 15:1179173X221124900. [PMID: 36090650 PMCID: PMC9449509 DOI: 10.1177/1179173x221124900] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2022] [Accepted: 08/22/2022] [Indexed: 11/16/2022] Open
Abstract
We analyzed reviews on tripadvisor.com from a random
sample of N = 477 hotels in ten large cities in the US to examine how well
existing policies protect guests from exposure to tobacco, electronic cigarette,
and cannabis (TEC) smoke. We examined the association between complaints per 100
reviews with hotel smoking policies, star rating, cost, brand, and location. Of
all TEC complaints, 80% were associated with thirdhand smoke residue lingering
in hotels from previous guests. Compared to the hotel brands with the best
records, the two worst-performing brands had 3.4- and 3.6-times higher complaint
rates (P < .001). Hotels with ≤2-star ratings had twice the
complaints as higher-rated hotels (P < .001). Compared to
100% smokefree hotels, those offering designated smoking rooms had a 35% higher
rate of complaints (P < .05). The success of some hotel
brands demonstrates it is feasible to protect guests by fully committing to,
implementing, and enforcing 100% smokefree building policies.

ENVIRONMENTAL RESEARCH 2018; 167:341-371. [PMID: 30096604 DOI: 10.1016/j.envres.2018.07.020] [Citation(s) in RCA: 36] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/29/2018] [Revised: 07/09/2018] [Accepted: 07/09/2018] [Indexed: 06/08/2023]
Abstract
OBJECTIVE The objective of this study is to perform a comprehensive review of the literature about thirdhand smoke (THS). METHODS Systematic review of all aspects of THS. Standard methodological procedures were used to search the following databases through April 2018: MEDLINE, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Cochrane Central Register of Controlled Trials (CENTRAL), and Web of Science (WOS) in Indo-European languages. To identify published grey literature, the first 200 hits from Google Scholar™ were evaluated. Clinical trial databases, conference proceedings, and reference lists from the identified articles were also searched. Two unblinded review authors independently assessed trials for inclusion in the review. These same reviewers also extracted study data in accordance with PRISMA guidelines. The study protocol was registered with PROSPERO (CRD42018083619). RESULTS Sixty-eight articles were included in this systematic review. Of these, 28 analyzed the concentration of nicotine as a component of THS (the most commonly-used method to measure THS in those studies was chromatography, followed by the mass spectrometry), 21 evaluated the exposure and impact of THS on health (11 studies analyzed the effect of THS in cells [human and animal], 4 in animals, 1 in adults, and 5 in children), 16 investigated the beliefs, behaviours, and policies related to THS, and 3 evaluated other aspects such as THS in e-cigarettes or hookahs. In these 68 studies, THS was determined by measuring the following components: nicotine (30 studies), nitrosamines (17 studies) and cotinine (15 studies). The findings from most of these studies suggest a potential health impact of THS exposure (i.e.: cytotoxicity, metabolic alterations in metabolism, in glycemia; or cell structure; alterations in liver, lung, skin and behaviour in mice), and low awareness about the risks of THS among the general population. CONCLUSIONS Numerous specific biomarkers of THS were evaluated, with the most common being nicotine, nitrosamines, and cotinine. The most common method of preparing THS dust samples were cotton wipes, while chromatography, used alone or coupled with mass spectrometry, was the most common analytical technique. We have tried to establish common bases after reviewing all the current literature of the THS although, there is great heterogeneity between the studies and we have not always succeeded. The studies in this review demonstrate the harmful effects of THS on health in cells, in animal models, and in people including children. However, in people, the long-term effects remain unknown and more research is needed. These studies show that knowledge about THS and its potential harmful effects are poorly understood among the general population. For this reason, THS should receive greater emphasis in education and awareness policies.

Abstract
PURPOSE To explore why some hotels have implemented 100% smoke-free policies voluntarily, the perceived consequences of doing so, and media responses. DESIGN Qualitative study of hotel management and quantitative content analysis of media coverage of smoke-free hotels. SETTING Hotels and media based in the United States. PARTICIPANTS Eleven representatives of 5 independent and 4 chain hotels. Other data included 265 news items about smoke-free hotels. METHOD We conducted 30-minute semi-structured interviews with hotel representatives and analyzed the data using qualitative content analysis. We also searched 3 online news databases for news items about hotels in our study, and collaboratively coded retrieved items; we analyzed the content and slant of news items. RESULTS Business considerations, including guest requests, competitor action, and cost savings, were the primary motivations for implementing 100% smoke-free guest-room policies. Health concerns played a minimal role. Hotels received positive feedback from customers and employees. Media coverage was favorable, emphasizing positive aspects of going smoke-free; the overall slant of news items was positive or neutral. However, few hotels marketed the change. CONCLUSIONS Since hotel customers and employees are likely to experience long periods of smoke exposure and smoke-free hotels appear to be so well received, it may be timely to pursue policies making all hotels smoke-free.
