PURPOSE: In the United States, the prevalence of the use of alternative tobacco products (ATPs) (e.g., hookahs, e-cigarettes, cigars/cigarillos) has increased sharply. As future health care providers, medical students will play a critical role in health promotion and disease prevention. This study investigated medical students' use, knowledge, and beliefs about cigarettes and ATPs. METHOD: In 2014, the authors surveyed all students enrolled at one medical school in New York City. The survey included questions about personal use of tobacco products, perceptions about the harms of ATPs and their role in disease causation, education about ATPs, and cessation training and practices related to ATPs and cigarettes. The authors compared results across medical school classes. RESULTS: Of 720 students, 431 (59.9%) completed the survey. Of those, 64 (14.7%) were current users of tobacco or smoking products, including cigarettes (17; 3.9%), ATPs (21; 4.8%), or marijuana (39; 8.9%). Many believed that ATPs contributed less than cigarettes to various diseases. Respondents received less cessation training regarding ATPs than cigarettes (P < .0001). They felt less confident providing ATP cessation counseling than cigarette cessation counseling (P < .0001) and were less likely to report counseling patients on ATP cessation than cigarette cessation (46 [10.7%] versus 280 [64.8%], P < .0001). CONCLUSIONS: A concerning percentage of surveyed medical students use tobacco products, including ATPs, and lack the knowledge, education, and cessation counseling skills to provide accurate information about them to patients. ATP education should be added to medical school curricula to address this gap.

BACKGROUND: Approximately one in 285 children will be diagnosed with cancer before reaching their 20th birthday. While both oncologists and parents report a preference that these children die at home rather than in a hospital, there are limited data exploring this issue in depth. PROCEDURE: We performed a retrospective analysis of national-level data from 1999 to 2011 from the National Center for Health Statistics "Underlying Cause of Death" database. Characteristics investigated included sex, race, age, ethnicity, cancer type, geographic location, and population density where the child lived. RESULTS: Of the 2,130 children with a death attributable to neoplasm in 2011, 37.6% (95% CI, 35.5-39.6%) died at home compared to 36.9% (95% CI, 35.0-38.8%) in 1999. In 2011, there were statistically significant racial differences between white, black, and Hispanic children across nearly every age group, with white children consistently most likely to die at home. Children of non-Hispanic origin were significantly more likely to die at home than Hispanic children (40.3% vs. 29.3%, P < 0.001). Children with CNS tumors are more likely to die at home than children with neoplasms as a whole, while children with leukemia are less likely. Statistically significant differences by race and ethnicity persist regardless of cancer type. CONCLUSIONS: There has been no significant change in the rate of children with cancer who die at home over the past decade. Racial and ethnic differences have persisted in end of life care for children with cancer with white non-Hispanic children being most likely to die at home. Pediatr Blood Cancer 2015;62:1403-1408.

BACKGROUND: Cannabis (marijuana) use and acceptance towards use are increasing in the US, and state-level policies are becoming more liberal. A wealth of research has been conducted to examine risk factors for use; however, studies rarely differentiate between different forms of marijuana. OBJECTIVE: We sought to determine prevalence of use and delineate who is at risk for use of hashish, a more potent form of marijuana. METHODS: We examined data from a nationally representative sample of high school seniors in the Monitoring the Future study (2007-2011; weighted n = 10 597). We determined how sociodemographic factors and reasons for marijuana use correlated with recent (12 month) hashish use. RESULTS: Prevalence of recent hashish use was 6.5% and it was used by 18.3% of recent marijuana users. Hashish and other marijuana use tended to share many of the same correlates; however, associations were often stronger for hashish use. Females were consistently at low risk for use and users of other drugs were consistently at high risk for use. Black students tended to be at low risk for hashish use. Low risk of identifying as Hispanic or religious and high risk of higher personal income or going out more evenings per week for fun disappeared when controlling for other drug use. Using marijuana because the student felt he/she was "hooked" nearly doubled the odds for hashish use. CONCLUSIONS: This was the first national study to examine prevalence and correlates of hashish use. These findings can inform prevention in a time of increasing popularity of marijuana use.

OBJECTIVE: There has been a rapid increase in the use of waterpipe tobacco and non-tobacco based shisha in many countries. Understanding the impact and effects of second-hand smoke (SHS) from cigarette was a crucial factor in reducing cigarette use, leading to clean indoor air laws and smoking bans. This article reviews what is known about the effects of SHS exposure from waterpipes. DATA SOURCES: We used PubMed and EMBASE to review the literature. Articles were grouped into quantitative measures of air quality and biological markers, health effects, exposure across different settings, different types of shisha and use in different countries. STUDY SELECTION: Criteria for study selection were based on the key words related to SHS: waterpipe, hookah, shisha and third-hand smoke. DATA EXTRACTION: Independent extraction with two reviewers was performed with inclusion criteria applied to articles on SHS and waterpipe/hookah/shisha. We excluded articles related to pregnancy or prenatal exposure to SHS, animal studies, and non-specific source of exposure as well as articles not written in English. DATA SYNTHESIS: A primary literature search yielded 54 articles, of which only 11 were included based on relevance to SHS from a waterpipe/hookah/shisha. CONCLUSIONS: The negative health consequences of second-hand waterpipe exposure have major implications for clean indoor air laws and for occupational safety. There exists an urgent need for public health campaigns about the effects on children and household members from smoking waterpipe at home, and for further development and implementation of regulations to protect the health of the public from this rapidly emerging threat.

BACKGROUND: In light of the current sentencing disparity (18:1) between crack and powder cocaine possession in the United States, we examined socioeconomic correlates of use of each, and relations between use and arrest, to determine who may be at highest risk for arrest and imprisonment. METHODS: We conducted secondary data analyses on the National Survey on Drug Use and Health, 2009-2012. Data were analyzed for adults age >/=18 to determine associations between use and arrest. Socioeconomic correlates of lifetime and annual use of powder cocaine and of crack were delineated using multivariable logistic regression and correlates of frequency of recent use were examined using generalized negative binomial regression. RESULTS: Crack users were at higher risk than powder cocaine users for reporting a lifetime arrest or multiple recent arrests. Racial minorities were at low risk for powder cocaine use and Hispanics were at low risk for crack use. Blacks were at increased risk for lifetime and recent crack use, but not when controlling for other socioeconomic variables. However, blacks who did use either powder cocaine or crack tended to use at higher frequencies. Higher education and higher family income were negatively associated with crack use although these factors were sometimes risk factors for powder cocaine use. CONCLUSIONS: Crack users are at higher risk of arrest and tend to be of lower socioeconomic status compared to powder cocaine users. These findings can inform US Congress as they review bills (e.g., The Smarter Sentencing Act), which would help eliminate cocaine-related sentencing disparities.

INTRODUCTION: U.S. adolescents increasingly use e-cigarettes. The perceived harm of e-cigarettes has not been described, nor has the correlation between harm perception and e-cigarette use been assessed. This study examines correlates of e-cigarette harm perception and use of e-cigarettes in a national survey. METHODS: We used cross-sectional nationally representative data from the 2012 National Youth Tobacco Survey (n = 24,658). Cross-tabulations and multivariate ordered probit and logistic regression models were employed to assess relative harm perception and e-cigarette use. RESULTS: Half of U.S. adolescents had heard of e-cigarettes. Of these, 13.2% (95% confidence interval [CI] = 11.7-14.9) and 4.0% (95% CI = 3.4-4.7) reported ever or currently using e-cigarettes, respectively. Of those aware of e-cigarettes, 34.2% (95% CI = 32.8-35.6) believed e-cigarettes were less harmful than cigarettes. Among those trying e-cigarettes, 71.8% (95% CI = 69.0-74.5) believed e-cigarettes were comparatively less harmful. Females and those >/= 17 years old were more likely to perceive e-cigarettes as more harmful relative to cigarettes, while on average Whites, users of other tobacco products, and those with family members who used tobacco were more likely to perceive e-cigarettes as comparatively safer. Among cigarette-naive e-cigarette users, use of other tobacco products and perceived harm reduction by e-cigarettes were, respectively, on average associated with 1.6 and 4.1 percentage-point increases in e-cigarette use. CONCLUSIONS: Perception of e-cigarettes as less harmful than conventional cigarettes was associated with increased e-cigarette use, including among cigarette-naive e-cigarette users. These findings should prompt further scientific investigation and merit attention from regulators.

BACKGROUND: Light smoking, consuming a few cigarettes daily, and intermittent, or nondaily, smoking patterns are increasingly common but carry health risks comparable to heavier smoking patterns. Nearly all smokers begin smoking as adolescents, who are at risk for developing these smoking patterns. Previous research suggests that smokers underestimate the risks associated with smoking. The extent to which adolescents perceive light and intermittent smoking as harmful has not been previously assessed. METHODS: Data from 24 658 US adolescents sampled by the 2012 National Youth Tobacco Survey, a national, school-based, cross-sectional survey, were examined. Cross-tabulations and multivariate ordered probit regression models were constructed to describe correlates of US adolescents' perception of light and intermittent smoking. RESULTS: Although most adolescents (88.0%; 95% confidence interval [CI], 87.2% to 88.8%) reported beliefs that a heavier smoking pattern is very harmful, only 64.3% (95% CI; 63.2% to 65.3%) and 33.3% (95% CI; 32.0% to 34.6%) reported that light and intermittent smoking, respectively, are very harmful. Conversely, nearly one-quarter of US adolescents believed intermittent smoking causes little or no harm. Males, younger adolescents, Hispanics, and non-Hispanic blacks were more likely than their peers to view light and intermittent smoking patterns as less harmful. Those who were already light or intermittent smokers, those who used other tobacco products, and those who had a family member who used tobacco were also less likely to view their smoking patterns as harmful. CONCLUSIONS: Misconceptions about the safety of light and intermittent smoking are widespread among US adolescents. Significant public health attention is needed to redress these misperceptions.

Tobacco use, primarily in the form of cigarettes, is the leading cause of preventable morbidity and mortality in the United States (U.S.). The adverse effects of tobacco use began to be recognized in the 1940's and new hazards of active smoking and secondhand smoke (SHS) exposure from cigarettes continue to be identified to this day. This has led to a sustained and wide-ranging array of highly effective regulatory, public health, and clinical efforts that have been informed by extensive scientific data, resulting in marked decreases in the use of cigarettes. Unfortunately, the dramatic recent decline in cigarette use in the U.S., has been accompanied by an upsurge in adolescent and young adult use of new, non-cigarette tobacco and nicotine-delivery products, commonly referred to as alternative tobacco products (ATPs). Commonly used ATPs include hookah, cigars, smokeless tobacco, and electronic cigarettes. While there have been a number of review articles that focus on adult ATP use, the purpose of this review is to provide an overview of what is, and is not known about emerging ATP use among U.S. adolescents on a national scale; as well as to identify research gaps in knowledge, and discuss future health and policy needs for this growing public health concern. This paper is not meant to systemically review all published survey data, but to present clear depiction of selected ATP usage in youth populations using national survey data.

The purpose of this review is to examine the rapidly expanding literature regarding the effects of prenatal tobacco and postnatal secondhand smoke (SHS) exposure on child health and development. Mechanisms of SHS exposure are reviewed, including critical periods during which exposure to tobacco products appears to be particularly harmful to the developing fetus and child. The biological, biochemical, and neurologic effects of the small fraction of identified components of SHS are described. Research describing these adverse effects of both in utero and childhood exposure is reviewed, including findings from both animal models and humans. The following adverse physical outcomes are discussed: sudden infant death syndrome, low birth weight, decreased head circumference, respiratory infections, otitis media, asthma, childhood cancer, hearing loss, dental caries, and the metabolic syndrome. In addition, the association between the following adverse cognitive and behavioral outcomes and such exposures is described: conduct disorder, attention-deficit/hyperactivity disorder, poor academic achievement, and cognitive impairment. The evidence supporting the adverse effects of SHS exposure is extensive yet rapidly expanding due to improving technology and increased awareness of this profound public health problem. The growing use of alternative tobacco products, such as hookahs (a.k.a. waterpipes), and the scant literature on possible effects from prenatal and secondhand smoke exposure from these products are also discussed. A review of the current knowledge of this important subject has implications for future research as well as public policy and clinical practice.

Abstract Objectives: There is debate about whether marijuana (cannabis) use is more dangerous than alcohol use. Although difficult to make objective comparisons, research is needed to compare relative dangers in order to help inform preventive efforts and policy. Methods: Data were analyzed from a nationally representative sample of high school seniors in the Monitoring the Future study (2007-2011; Weighted n = 7437; modal age: 18) who reported lifetime use of alcohol or marijuana. Students were asked to indicate whether they experienced various adverse psychosocial outcomes resulting from use of each substance. We examined which outcomes were more prevalent for each substance. Results: Compared to alcohol use, marijuana use was more commonly reported to compromise relationships with teachers or supervisors, result in less energy or interest, and result in lower school or job performance. Compared to marijuana use, alcohol was more commonly reported to compromise relationships with friends and significant others; it was also reported to lead to more regret (particularly among females), and driving unsafely. Marijuana users were more likely to report no adverse outcomes. Females and white students were more likely to report various adverse outcomes and higher frequency use of each substance also increased occurrences of reported adverse outcomes. Conclusions: Marijuana and alcohol are associated with unique adverse psychosocial outcomes. Outcomes differ by sex and race/ethnicity, and perception or experience of outcomes may also be related to legal status and associated stigma. Public health interventions may be more effective by focusing on harm reduction strategies for these drug-specific outcomes.
