INTRODUCTION: Smoking cessation among adults is associated with increased happiness. This association has not been measured in parents, a subset of adults who face uniquely stressful and challenging circumstances that can affect happiness. AIMS: To determine if parental smoking cessation is associated with increased happiness and to identify characteristics of parental quitters who experience increased happiness. METHODS: 1355 parents completed a 12-month follow-up interview from a U...

Thirdhand smoke (THS) is the fraction of cigarette smoke that persists in indoor environments after smoking. We investigated the effects of neonatal and adult THS exposure on bodyweight and blood cell populations in C57BL/6 J mice. At the end of neonatal exposure, THS-treated male and female mice had significantly lower bodyweight than their respective control mice. However, five weeks after neonatal exposure ended, THS-treated mice weighed the same as controls. In contrast, adult THS exposure did not change bodyweight of mice...

BACKGROUND: Similarly to secondhand smoke (SHS), thirdhand smoke (THS) beliefs may be correlated with smoking behaviors and smokefree policies in the home. Thus, there is a need to develop and validate measures to assess beliefs about THS. METHODS: A list of 19 items related to THS were generated by an expert panel and tested in a pilot study. Based on results from an exploratory factor analysis, two factors emerged: THS persistence in the environment and THS impact on health...

Secondhand and third hand smoke (SHS, THS) exposure is prevalent in multi-unit housing (MUH). Minorities and low-income MUH residents are disproportionally exposed to SHS and THS compared to other populations. This study describes the characteristics, attitudes, knowledge, and behaviors related to SHS, THS and marijuana smoke exposure (MSHS) of a sample of Hispanic tenants in randomly selected MUH units in eastern metro Los Angeles (n = 402). Although most participants (97%) banned smoking inside their homes, 80% reported infiltration of SHS inside their apartments within the last year...

INTRODUCTION: Routine biochemical assessment of tobacco smoke exposure could lead to more effective interventions to reduce or prevent secondhand smoke (SHS)-related disease in adolescents. Our aim was to determine using urine cotinine (major nicotine metabolite) measurement the prevalence of tobacco smoke exposure among adolescents receiving outpatient care at an urban public hospital. METHODS: Surplus urine was collected in 466 adolescents attending pediatric or urgent care clinics at San Francisco General Hospital, serving families with lower levels of income and education, in 2013-14...

Thirdhand smoke (THS) is the contamination that persists after secondhand tobacco smoke has been emitted into air. It refers to the tobacco-related gases and particles that become embedded in materials, such as the carpet, walls, furniture, blankets, and toys. THS is not strictly smoke, but chemicals that adhere to surfaces from which they can be released back into the air, undergo chemical transformations and/or accumulate. Currently, the hazards of THS are not as well documented as the hazards of secondhand smoke (SHS)...

INTRODUCTION: Over the past few decades, tobacco control efforts have made great strides in making smoke-free air the norm; 30 states in the United States have implemented 100% smoke-free laws. Despite this progress, the evolution of the measurement of secondhand smoke (SHS) exposure has lagged. METHODS: Cognitive testing was used to explore the functioning and limitations of current SHS surveillance items; many items are frequently used for statewide or national surveillance...

Recent discussion has focused on another form of exposure to tobacco - thirdhand smoke (THS) - consisting of residual pollutants from cigarette smoke that remain in environments. The main concern with THS is based on the presence and persistence of many toxic compounds, some specific nitrosamines from tobacco that have carcinogenic activity. Little is known about THS, and few people are aware of its existence and potential health repercussions, thus highlighting the need to shed light on the subject and incorporate it into the public health debate, as was done with passive smoking several years ago...

INTRODUCTION: Reports on involuntary tobacco smoke exposure in children have focused mostly on secondhand smoke (SHS) from smoking inside the home. We studied the separate and combined prevalence of SHS exposure from multiple sources and thirdhand smoke (THS) and the associations with respiratory symptoms in Hong Kong adolescents. METHODS: In 2010-11, 61810 Secondary 1 (US Grade 7) to 7 students reported their smoking status, respiratory symptoms and exposure to 4 sources of tobacco smoke in the past 7 days...

We examined the correlation between the odor concentration and the chemical composition of environmental tobacco smoke (ETS). Three types of ETS samples were prepared: secondhand smoke (SHS), thirdhand smoke (THS), and field ETS samples from an outside smoking area. The odor concentrations of the ETS, SHS, and THS samples were determined by the triangle-odor-bag method, and the chemical compositions were determined by proton transfer mass spectrometry. The odor concentration of the SHS samples was three or four orders of magnitude higher than that of the field ETS samples, and three orders of magnitude higher than that of the THS samples...

The risks associated to tobacco smoking are not ceased with smoke extinction. Many toxic compounds remain in the environment after the cigarette is extinguished and accumulated in the air or on surfaces. However, little is known about the risks of this exposure. The aim of this study was to evaluate procedures to collect thirdhand smoke (THS) and prepare the samples to perform three in vitro toxicity tests. Cellulose papers and cotton wipes were used to impregnate with nicotine solution and smoke cigarette in a chamber or in smoker's home...

Thirdhand cigarette smoke (THS) was recently recognized as an environmental health hazard; however, little is known about it effects on cells. Mitochondria are sensitive monitors of cell health and report on environmentally induced stress. We tested the effects of low levels of THS extracted from terry cloth on mitochondrial morphology and function using stem cells with well-defined mitochondria. Concentrations of THS that did not kill cells caused stress-induced mitochondrial hyperfusion (SIMH), which was characterized by changes in mitochondrial morphology indicative of fusion, increased mitochondrial membrane potential (MMP), increased ATP levels, increased superoxide production, and increased oxidation of mitochondrial proteins...

Thirdhand smoke (THS) refers to tobacco smoke contaminants and by-products that remain in the environment after a cigarette is extinguished. The purpose of this study was to assess beliefs and behaviors regarding THS among healthcare professionals, and to examine associations among smoking attitudes/beliefs, provider demographics, and THS beliefs and behaviors. Healthcare professionals (N = 204) at a comprehensive cancer center and affiliated general hospital in a northeastern urban area completed online questionnaires...

Thirdhand smoke (THS) is the accumulation of secondhand smoke on environmental surfaces. THS is found on the clothing and hair of smokers as well as on surfaces in homes and cars of smokers. Exposure occurs by ingestion, inhalation and dermal absorption. Children living in homes of smokers are at highest risk because they crawl on the floor, touch parents' clothing/hair and household objects. Using mice exposed to THS under conditions that mimic exposure of humans, we show that THS increases cellular oxidative stress by increasing superoxide dismutase (SOD) activity and hydrogen peroxide (H2O2) levels while reducing the activity of antioxidant enzymes catalase and glutathione peroxidase (GPx) that break down H2O2 into H2O and O2...

We tested the toxicity of thirdhand smoke (THS) using two controlled laboratory exposure scenarios and low levels of THS. One exposure modeled THS in a car parked outdoors, while the second modeled THS in a room without sunlight. The fabrics were exposed to cigarette smoke and then extracted in culture medium. Concentrations of nicotine, nicotine related alkaloids, and tobacco specific nitrosamines (TSNAs) were determined in fresh and aged extracts. The concentration of TSNAs increased with aging in the indoor experiment...

Thirdhand tobacco smoke (THS) constitutes a poorly understood pathway of exposure of non-smokers, especially toddlers, to tobacco-related carcinogens. However, to date most of the carcinogens present in tobacco smoke have not been detected in THS and, therefore, the significance of THS health risk is still unknown. In this study, we have compared the performance of two analytical methods - one based on gas chromatography coupled to ion trap mass spectrometry detection (GC-IT-MS) and the other on comprehensive two-dimensional gas chromatography coupled to a nitrogen chemiluminescence detector (GC×GC-NCD) - for simultaneously determining, in settled house dust, the presence of 16 organic nitrogen carcinogens already detected in tobacco smoke...

BACKGROUND: Tobacco has regained the status of the world's number two killer behind heart/vascular disease. Thirdhand smoke (THS) residue and particles from secondhand smoke (SHS) are suspected health hazards (eg, DNA damage) that are likely to contribute to morbidity and mortality, especially in vulnerable children. THS is easily transported and deposited indoors, where it persists and exposes individuals for months, creating potential health consequences in seemingly nicotine-free environments, particularly for vulnerable patients...

Despite the progressive adoption of smoking bans in public spaces, children living in multi-unit housing remain at risk of exposure to secondhand smoke (SHS) and thirdhand smoke (THS). Hispanic populations in California are particularly vulnerable to the harmful effects of SHS and THS because a large proportion of Hispanics live in multi-unit housing. Three focus groups were conducted in the fall of 2012 (in Spanish and English, N = 24) to understand Hispanics' knowledge of and experiences with SHS and THS, including barriers to avoiding smoke exposure and strategies for protecting their homes from smoke...
