Perception of harm is strongly associated with complete ban on in-home cannabis smoking: A cross-sectional study
Our study demonstrates perceiving cSHS as harmful is strongly associated with having a complete in-home cannabis smoking ban. With almost a third of US adults perceiving cSHS as at least "mostly safe", there is strong need to educate the general population about potential risks associated with cSHS exposure to raise awareness and encourage adoption of household rules prohibiting indoor cannabis smoking
Evaluation of a Social Media Campaign Designed to Increase Awareness of Thirdhand Smoke among California Adults
Despite a growing body of research outlining the harms of thirdhand smoke (THS), the public remains generally unaware of risks and exposure routes. This project built on past tobacco prevention campaigns and the tenants of McGuire’s input-output model to implement and evaluate a seven-month Facebook-disseminated campaign seeking to improve THS awareness among California adults (n = 1087). Multilinear regression showed that THS-related knowledge (…
The Associations of Trans-3′-Hydroxy Cotinine, Cotinine, and the Nicotine Metabolite Ratio in Pediatric Patients with Tobacco Smoke Exposure
(1) Background: Trans -3'-hydroxy cotinine (3HC) and cotinine (COT) are tobacco smoke exposure (TSE) biomarkers and the 3HC/COT ratio is a marker of CYP2A6 activity, an enzyme which metabolizes nicotine. The primary objective was to assess the associations of these TSE biomarkers with sociodemographics and TSE patterns in children who lived with ≥1 smoker. (2) Methods: A convenience sample of 288 children (mean age (SD) = 6.42 (4.8) years) was re…
Policy-relevant differences between secondhand and thirdhand smoke: Strengthening protections from involuntary exposure to tobacco smoke pollutants
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…

Comparison of Levels of Three Tobacco Smoke Exposure Biomarkers in Children of Smokers
Objectives : Cotinine, 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL), and N-oxides are biomarkers of tobacco smoke exposure (TSE) used to assess short- and longer-term TSE. The objective of this study was to assess the associations between these TSE biomarkers, sociodemographics, parental smoking, and child TSE patterns among 0-17-year-olds. Methods : A convenience sample of 179 pediatric patients (mean (SD) age = 7.9 (4.3) years) who live…
Comparison of Liquid Chromatography Mass Spectrometry and Enzyme-Linked Immunosorbent Assay Methods to Measure Salivary Cotinine Levels in Ill Children
Objective : Cotinine is the preferred biomarker to validate levels of tobacco smoke exposure (TSE) in children. Compared to enzyme-linked immunosorbent assay methods (ELISA) for quantifying cotinine in saliva, the use of liquid chromatography tandem mass spectrometry (LC-MS/MS) has higher sensitivity and specificity to measure very low levels of TSE. We sought to compare LC-MS/MS and ELISA measures of cotinine in saliva samples from children over…
The Association of Environmental Tobacco Smoke Exposure and Inflammatory Markers in Hospitalized Children
Environmental tobacco smoke (ETS) exposure is associated with altered cytokine levels in children. We sought to examine ETS exposure prevalence and the relationship between ETS exposure and cytokine levels in a sample of hospitalized children. (2) Methods: Inflammatory markers (IL-8, IL-1β, IL-10, and TNF-α) and cotinine were measured in saliva of hospitalized, nonsmoking children (N = 112). To assess the association between ETS exposure and immu…

A Casino goes smoke free: A longitudinal study of secondhand and thirdhand smoke pollution and exposure
Long-term smoking in a casino creates deep THS reservoirs that persist for months after a smoking ban. A complete smoking ban immediately improves air quality and significantly reduces exposure to SHS and THS. However, THS reservoirs contribute to continued low-level exposure to toxicants. To accelerate the effect of smoking bans, remediation efforts should address specific THS reservoirs, which may require intensive cleaning as well as replaceme…
Preliminary evidence that high levels of nicotine on children’s hands may contribute to overall tobacco smoke exposure

When smokers quit: Exposure to nicotine and carcinogens persists from thirdhand smoke pollution
Homes of smokers remained polluted with THS for up to 6 months after cessation. Residents continued to be exposed to THS toxicants that accumulated in settled house dust and on surfaces before smoking cessation. Further research is needed to better understand the consequences of continued THS exposure after cessation and the efforts necessary to remove THS

Thirdhand smoke contamination in hospital settings: Assessing exposure risk for vulnerable paediatric patients: Table 1
THS appears to be ubiquitous, even in closely guarded healthcare settings. Future research will address potential health consequences and THS-reduction policies. Ultimately, hospital policies and interventions to reduce THS transport and exposure may prove necessary, especially for immunocompromised children
A quantitative meta-analysis of neurocognitive functioning in posttraumatic stress disorder
Posttraumatic stress disorder (PTSD) is associated with regional alterations in brain structure and function that are hypothesized to contribute to symptoms and cognitive deficits associated with the disorder. We present here the first systematic meta-analysis of neurocognitive outcomes associated with PTSD to examine a broad range of cognitive domains and describe the profile of cognitive deficits, as well as modifying clinical factors and study…
Thirdhand smoke and exposure in California hotels: Non-smoking rooms fail to protect non-smoking hotel guests from tobacco smoke exposure
Partial smoking bans in hotels do not protect non-smoking guests from exposure to tobacco smoke and tobacco-specific carcinogens. Non-smokers are advised to stay in hotels with complete smoking bans. Existing policies exempting hotels from complete smoking bans are ineffective
Towards smoke-free rental cars: An evaluation of voluntary smoking restrictions in California
Existing policies and practices were successful in lowering THS pollution levels in non-smoker cars compared with smoker cars. However, policies failed in providing smoke-free rental cars; THS levels were not as low as those found in private cars of non-smokers with in-car smoking bans. Major obstacles include inconsistent communication with customers and the lack of routine monitoring and enforcement strategies. Strengthening policies and their …
Thirdhand Tobacco Smoke: Emerging Evidence and Arguments for a Multidisciplinary Research Agenda
BACKGROUND: There is broad consensus regarding the health impact of tobacco use and secondhand smoke exposure, yet considerable ambiguity exists about the nature and consequences of thirdhand smoke (THS). OBJECTIVES: We introduce definitions of THS and THS exposure and review recent findings about constituents, indoor sorption-desorption dynamics, and transformations of THS; distribution and persistence of THS in residential settings; implication…
When smokers move out and non-smokers move in: Residential thirdhand smoke pollution and exposure
These findings indicate that THS accumulates in smokers' homes and persists when smokers move out even after homes remain vacant for 2 months and are cleaned and prepared for new residents. When non-smokers move into homes formerly occupied by smokers, they encounter indoor environments with THS polluted surfaces and dust. Results suggest that non-smokers living in former smoker homes are exposed to THS in dust and on surfaces
Households contaminated by environmental tobacco smoke: Sources of infant exposures
Dust and surfaces in homes of smokers are contaminated with ETS. Infants of smokers are at risk of ETS exposure in their homes through dust, surfaces, and air. Smoking outside the home and away from the infant reduces but does not completely protect a smoker's home from ETS contamination and a smoker's infant from ETS exposure

The Ethnic Mentor Undergraduate Program: A Brief Description and Preliminary Findings
The Ethnic Mentor Undergraduate (EMU) Program targets students from traditionally underrepresented ethnic backgrounds and aims at fostering skills and attitudes necessary to persist to graduation. Findings indicate that EMU protégés perform better than the university-wide average and that drop-out rates are reduced. Implications for mentoring programs are discussed
Social Support from Friends and Psychological Distress Among Elderly Persons: Moderator Effects of Age
In this study, the relationships among age, sex, friend support, and psychological distress are examined among elderly persons. Structural equation modeling and a longitudinal design are used to examine direct, indirect, and moderator (interaction) effects over a 22-month interval. Findings suggest that different causal processes operate among persons over the age of 70 (old-old) and those 50 to 70 years (young-old); the cross-lagged effects of f…

The Influence of Living Alone on Depression in Elderly Persons
The mental health effects of living alone on elderly persons are not well known. Using multiple regression models, the authors attempted to distinguish the influence of living alone on depressive symptoms from the influence of other highly relevant variables: social support, stressors, age, sex, and marital status. The data derive from a stratified community probability sample of persons 50 years of age and older. The authors find that elderly pe…

Decision rules for selecting effect sizes in meta-analysis: A review and reanalysis of psychotherapy outcome studies
This study deals with some of the judgmental factors involved in selecting effect sizes from within the studies that enter a meta-analysis. Particular attention is paid to the conceptual redundancy rule that Smith, Glass, and Miller (1980) used in their study of the effectiveness of psychotherapy for deciding which effect sizes should and should not be counted in determining an overall effect size. Data from a random sample of 25 studies from Smi…
High School Study Habits and Early College Achievement
High School Study Habits and Early College Achievement
The influence of high school study habits on achievement in high school and during the first semester of college was examined, using data from 159 female and 93 male freshmen. The same study habits that contributed to success in high school are unrelated to academic achievement during the first semester in college. The findings suggest that college freshmen need to acquire new study habits to be academically successful

The effects of widowhood on social support from significant others
The effects of widowhood on social support from significant others are variously predicted by the decremental model, the continuity model, and the compensatory model. This study distinctly tested for these possible effects to discern whether they vary with specific types and sources of support. We examined possible changes over 22 months by comparing two recently widowed groups with matched controls of married and unmarried persons, each from a c…
