Cigarette use is increasing among people with illicit substance use disorders in the United States, 2002-14: emerging disparities in vulnerable populations.

ABSTRACT: BACKGROUND AND AIMS:While cigarette smoking has declined over time, it is not known whether this decline has occurred similarly among individuals with substance use disorders (SUDs) in the United States (US). The current study estimated trends in smoking from 2002 to 2014 among US individuals with and without SUDs. DESIGN:Linear time trends of current smoking prevalence were assessed using logistic regression models. SETTING:United States; data were drawn from the 2002 to 2014 National Household Survey on Drug Use (NSDUH), an annual US cross-sectional study. PARTICIPANTS:A representative, population-based sample of US individuals age 12 yeas and older (total analytical population: n = 723?283). MEASUREMENTS:Past-month current smoking was defined as having smoked at least 100 lifetime cigarettes and reporting smoking part or all of at least one cigarette during the past 30 days. Respondents were classified as having any SUD if they met criteria for abuse or dependence for one or more of the following illicit drugs: cannabis, hallucinogens, inhalants, tranquilizers, cocaine, heroin, pain relievers, simulants and sedatives. A second SUD variable included all drugs listed above excluding cannabis use disorder (CUD). An additional variable included respondents who met criteria for cannabis abuse or dependence. FINDINGS:Among those with any SUD, the prevalence of smoking did not change from 2002 to 2014 (P = 0.08). However, when CUDs were separated from other SUDs, a significant increase in prevalence of smoking was observed among those with SUDs excluding CUDs (P < 0.001), while smoking decreased among those with CUDs (P < 0.001). Smoking declined among those without SUDs (P < 0.001). In 2014, smoking remained significantly more common among those with any SUD (55.48%), SUDs excluding CUDs (63.34%) and CUDs (51.34%) compared with those without these respective disorders (18.16, 18.55 and 18.64%; P < 0.001). CONCLUSIONS:The prevalence of cigarette smoking in the United States increased from 2002 to 2014 among people with substance use disorders (SUDs) excluding cannabis use disorders (CUDs) and declined among those with CUDs and without SUDs. In 2014, the prevalence of smoking was multifold higher among those with SUDs, including CUDs, compared with those without SUDs.

Project description:Objectives Substance use during pregnancy is a significant public health issue. Prenatal substance use increased in the past decade while prenatal cigarette smoking has remained stable. Co-use of tobacco and other drugs is a concern because of potential additive risks. This study aims to describe the prevalence rates of substance use among pregnant women and examine the association between smoking status (nonsmoker, recent quitter and current smoker) and other drug use. Methods In this cross-sectional study, pregnant women (n?=?500) were recruited from two obstetric practices to complete three substance use screeners and have their urine tested for 12 different drug classes, including cannabis, opioids and cocaine. Participants were divided into three groups based on survey responses: nonsmokers, recent quitters (smoked in the month prior to pregnancy but not past month) and current smokers (past-month). Results Approximately 29% of participants reported smoking in the month before pregnancy. During pregnancy, 17, 12 and 71% were current smokers, recent quitters and nonsmokers respectively. Overall prevalence of illicit or prescription drug use in pregnancy was 27%. Cannabis was the most common drug used in pregnancy with prevalence of 22%, followed by opioids (4%), cocaine (1%), tricyclic antidepressants (TCAs) (1%), amphetamines (1%), and benzodiazepines (1%). On multivariable logistic regression, smoking in pregnancy was associated with a positive urine drug screen; with adjusted odds ratio (aOR) 4.7 (95% CI 2.6-8.3) for current smokers and 1.6 (95% CI 0.8-3.3) for recent quitters. Factors negatively associated with positive drug screen were second and third trimester pregnancies, 0.5 (0.3-0.9) and 0.3 (0.2-0.6) respectively; and employment, 0.5 (0.3-0.8). Conclusions for Practice Co-use of tobacco and illicit drugs, particularly cannabis, is relatively high during pregnancy. Additional research is needed to understand the health implications of co-use versus use of tobacco only. Given the strong association between smoking and other drug use, clinicians should routinely assess for illicit drug use in women who smoke during pregnancy.

Project description:BackgroundPrenatal cocaine exposure (PCE) is associated with increased rates of illicit-substance use during adolescence. In addition, both PCE and illicit-substance use are associated with alterations in cortico-striato-limbic neurocircuitry, development of which is ongoing throughout adolescence. However, the relationship between illicit-substance use, PCE and functional neural responses has not previously been assessed concurrently.MethodsSixty-eight adolescents were recruited from an ongoing longitudinal study of childhood and adolescent development. All participants had been followed since birth. Functional magnetic resonance imaging (fMRI) data were acquired during presentation of personalized stressful, favorite-food and neutral/relaxing imagery scripts and compared between 46 PCE and 22 non-prenatally-drug-exposed (NDE) adolescents with and without lifetime illicit-substance use initiation. Data were analyzed using multi-level ANOVAs (pFWE<.05).ResultsThere was a significant three-way interaction between illicit-substance use, PCE status and cue condition on neural responses within primarily cortical brain regions, including regions of the left and right insula. Among PCE versus NDE adolescents, illicit-substance use was associated with decreased subcortical and increased cortical activity during the favorite-food condition, whereas the opposite pattern of activation was observed during the neutral/relaxing condition. Among PCE versus NDE adolescents, illicit-substance use during stress processing was associated with decreased activity in cortical and subcortical regions including amygdala, hippocampus and prefrontal cortex. Neural activity within cortico-striato-limbic regions was significantly negatively associated with subjective ratings of anxiety and craving among illicit-substance users, but not among non-users.ConclusionsThese findings suggest different neural substrates of experimentation with illicit drugs between adolescents with and without in utero cocaine exposure.

Project description:IntroductionPrior work suggests that the prevalence of cigarette smoking is persistently higher among people with mental health problems, relative to those without. Lower quit rates are one factor that could contribute to higher prevalence of smoking in this group. This study estimated trends in the cigarette quit rates among people with and without past-month serious psychological distress (SPD) from 2008 to 2016 in the United States.MethodsData were drawn from 91 739 adult participants in the 2008-2016 National Survey on Drug Use and Health, a repeated, cross-sectional, national survey. Linear time trends of cigarette quit rates, stratified by past-month SPD, were assessed using logistic regression models with continuous year as the predictor.ResultsCigarette quit rates among individuals with past-month SPD were lower than among those without SPD every year from 2008 to 2016. Quit rates did not change appreciably among those with past-month SPD (odds ratio = 1.02 [0.99, 1.06]) from 2008 to 2016, whereas quit rates increased among those without past-month SPD (odds ratio = 1.02 [1.01, 1.02]).ConclusionsIn the United States, quit rates among individuals with past-month SPD are approximately half than quit rates of those without SPD and have not increased over the past decade. This discrepancy in quit rates may be one factor driving increasing disparities in prevalence of smoking among those with versus without mental health problems. Tobacco control efforts require effective and targeted interventions for those with mental health problems.ImplicationsCigarette smoking quit rates have not increased among persons with serious mental health problems over the past decade. This work extends prior findings showing that smoking prevalence is not declining as quickly among persons with serious mental health problems. Findings suggest that diverging trends in quit rates are one possible driver of the persistent disparity in smoking by mental health status. Innovation in both tobacco control and targeted interventions for smokers with mental health problems is urgently needed.

Project description:IntroductionExposure to violence victimization may help explain disparities of substance use among gender-nonconforming youth (i.e., those whose gender expression differs from societal expectations).MethodsIn 2015, three large urban school districts (2 in California and 1 in Florida) conducted a Youth Risk Behavior Survey that included the assessment of gender expression among a racially/ethnically diverse population-based sample of 6,082 high school students. Five categories of violence victimization were assessed (felt unsafe at school, threatened or injured with a weapon at school, bullied at school, electronically bullied, and forced sexual intercourse). In 2019, the effect of violence victimization on substance use disparities was examined by calculating sex-stratified prevalence ratios by gender nonconformity, adjusted for sexual identity, race/ethnicity, and grade (adjusted prevalence ratio 1 [APR1]), and comparing these with prevalence ratios adjusted for those variables plus violence victimization (adjusted prevalence ratio 2 [APR2]).ResultsAmong female students, only being threatened or injured with a weapon was significantly (p<0.05) associated with gender nonconformity and there were no substance use disparities by gender nonconformity. Among male students, every category of violence victimization was more prevalent among gender-nonconforming than among gender-conforming students and most substance use categories demonstrated significant gender nonconformity disparities. After controlling for violence victimization, these disparities decreased but remained statistically significant for the use of cocaine (APR1=2.84 vs APR2=1.99), methamphetamine (APR1=4.47 vs APR2=2.86), heroin (APR1=4.55 vs APR2=2.96), and injection drug use (APR1=7.90 vs APR2=4.72).ConclusionsSchool-based substance use prevention programs may benefit from strategies that support gender diversity and reduce violence victimizations experienced by gender-nonconforming students, by providing a safe and supportive school environment.
