Driving Under the Influence of Alcohol, Cannabis, and Delta-8 THC: Perceived Likelihood, Risk Perceptions, and Behaviors.

Driving under the influence (DUI) of alcohol or cannabis poses public health risks. Little is known about DUI of Delta-8 THC, a newer cannabis product. Using 2022 survey data among 189 U.S. adults ages 18-25 (58.73% male, 59.26% non-Hispanic White), multivariable logistic regression examined substance-specific (alcohol, cannabis, Delta-8) DUI perceived likelihood and risk in relation to past-year DUI among those with past-year use of each. Overall, 72.49% reported past-year alcohol use, 50.53% cannabis, and 22.46% Delta-8. Among those reporting past-year use of each respective substance, 33.58% reported DUI of alcohol, 32.63% cannabis, and 57.14% Delta-8. On average, participants had the same DUI perceived likelihood ("somewhat unlikely") across substances and perceived alcohol DUI as riskiest. Higher alcohol DUI perceived likelihood and lower perceived risk were associated with alcohol-related DUI. Greater cannabis-related perceived likelihood (but not risk) was associated with cannabis-related DUI. Neither Delta-8 DUI perceived likelihood nor risk were associated with Delta-8 DUI. In sum, perceived DUI likelihood for alcohol, cannabis, or Delta-8 tended to be similar. Among those with past-year use of each, the proportion of DUI was highest for Delta-8. Interventions should target DUI-related perceived likelihood and promote protective behavioral strategies that reduce substance-specific DUI risk.

How Are Retailers Describing Delta-8 THC?A Mixed-Methods Study in Fort Worth, Texas.

OBJECTIVE: Delta-8 tetrahydrocannabinol (THC) is a largely unregulated psychoactive substance rising in popularity in the United States. This study aimed to understand how retailers explained Delta-8 THC to potential customers and if these descriptions were associated with socioeconomic deprivation surrounding the retail location. METHOD: In Fort Worth, Texas, stores with retail alcohol, cannabidiol (CBD), or tobacco licenses were called. Among the 133 stores that sold Delta-8 THC, 125 retailers (94%) answered the question "What is Delta-8?" Qualitative methods were used to identify related themes; logistic regression models tested associations between themes and area deprivation index (ADI) scores, a measure of socioeconomic deprivation (1-10; 10 = most deprived areas). RESULTS: Retailers often compared Delta-8 THC to other substances (49%). Although most often described as a type of cannabis (34%), several retailers likened Delta-8 to CBD (19%) or hemp (7%), which are nonpsychoactive. Retailers also described potential effects from use (35%). Some retailers reported that they were unsure of what Delta-8 was (21%), told surveyors to look it up themselves (6%), or withheld information (9%). Higher ADI scores were associated with higher odds of retailers communicating limited information (odds ratio = 1.21, 95% CI [1.04, 1.40], p = .011). CONCLUSIONS: Study findings may inform the development of marketing regulations, as well as informational campaigns for both retailers and consumers.

Midwives' knowledge and perceived barriers to screening alcohol use among pregnant women in a southwestern US state.

INTRODUCTION: Alcohol consumption during pregnancy can produce multiple damaging outcomes to the foetus, commonly referred to as fetal alcohol spectrum disorders (FASD). FASD represents the leading non-genetic cause of preventable birth defects in the United States where alcohol guidelines recommend pregnant woman abstain from alcohol use. This study examined: (i) midwives' knowledge, attitude and intent to screen for prenatal alcohol use; and (ii) assessed perceived barriers to communicating alcohol-related information. METHODS: Using an online questionnaire, data were obtained from midwives (n = 61) in a southwestern US state between March and May 2018. Descriptive statistics were used to describe midwives' knowledge, attitude, intent and perceived barriers. RESULTS: Several midwives considered one alcoholic beverage per occasion to be safe for the foetus (20.3%), some thought alcohol was safe during the 3rd trimester (14.8%) only and few thought it was safe in all trimesters. Many midwives (63.3%) were unaware that the TWEAK and T-ACE were validated alcohol screening tools for pregnant women. Furthermore, most midwives (>50%) agreed that limited time with patients, a need for additional training and lack of information on referral resources interfered with their sharing of alcohol abstinence guidelines. Midwives reported highly favourable attitudes and intentions toward sharing alcohol abstinence messages with their pregnant patients. DISCUSSION AND CONCLUSIONS: More in-depth research and larger samples are needed to explore barriers (knowledge gaps, limited time with patients, need for additional training) that hinder midwives' dissemination of abstinence messages to pregnant women and limit the uptake of validated alcohol screening tools.

Longitudinal Change in Alcohol Use and Motivations for Drinking Among Asian American College Students.

BACKGROUND: Asian Americans are understudied in the literature on alcohol, due to data limitations and the perception that they are at low risk for alcohol misuse. Yet, certain subpopulations-such as college students-may be at higher risk. The current study examined longitudinal change in alcohol use and motivations for drinking among Asian American students. We tested for differences by nativity status, ethnic origin, and gender and examined whether motivations covaried with alcohol use. METHODS: Asian American first-year college students (N = 199, 45.7% female, 37.7% foreign-born) attending a US university were identified through stratified random sampling using registrar information. For 7 consecutive semesters, students completed online surveys about their behaviors and beliefs. RESULTS: Multilevel models demonstrated that alcohol use and alcohol-related motivations increased over time. US-born students consistently consumed more alcoholic drinks, reached higher peak drinking levels, and drank more frequently than foreign-born students; however, motivations did not differ by nativity status. Chinese American students consumed less alcohol, drank less, and were more motivated to avoid alcohol-related consequences than students of other/multiple heritage ethnic origins. Each motivation subscale was associated with alcohol use at the between-person level. Likewise, within-person variability in motivations was linked to variability in drinking across semesters. Controlling for other motivations, drinking for fun emerged as the strongest correlate of alcohol use variability. CONCLUSIONS: Alcohol misuse was highest among US-born students and those with higher motivations for drinking. Furthermore, alcohol use varied in tandem with motivations, suggesting that motivations may be a useful intervention target among this population.

Underage drinkers' first experience consuming a popular brand of supersized alcopop.

BACKGROUND: Supersized alcopops are sugar sweetened beverages with high alcohol concentration; Four Loko is the most commonly consumed brand among underage drinkers. OBJECTIVES: The current study examined the prevalence and correlates of Four Loko consumption, as well as drinking location, beverage source, quantity consumed, and alcohol-related consequences among students who consumed the product before age 21. METHODS: Undergraduate drinkers (n = 1,019; 53.5% female) attending public universities in Florida, Montana, and Virginia completed a classroom survey. Multivariable logistic regression models examined first-time Four Loko experiences among students under age 21 at the time of the drinking episode (n = 336). RESULTS: Among drinkers, 46% had consumed Four Loko. The vast majority (93%) drank the product before age 21. During their first Four Loko drinking episode, 57% consumed at least one can and 10% drank two or more cans. Among underage drinkers, being male (AOR = 6.8), paying for the Four Loko (AOR = 3.1), and earlier age of alcohol initiation (AOR = 0.8) were associated with greater odds of drinking at least one can. Among underage drinkers who finished at least one can, 36% blacked out and 21% vomited. The odds of blacking out and vomiting were greater if the participant drank at least one can (AOR = 6.0, AOR = 4.0). Students in states that sold Four Loko with higher alcohol-by-volume were more likely to blackout (AOR = 2.0) and vomit (AOR = 2.5). CONCLUSIONS: Delaying the age of first alcohol use may have protective effects on supersized alcopop consumption. Increased enforcement of existing laws is needed to prevent underage access to Four Loko. Further, laws that reduce the alcohol content of Four Loko may reduce negative consequences associated with its consumption.

The Federal Trade Commission's mandated Four Loko labeling fails to facilitate accurate estimation of alcohol content by college students.

BACKGROUND: Four Loko, the leading supersized alcopop brand, is a pre-mixed alcoholic beverage containing up to 5.5 standard alcoholic drinks in a can. In 2013, the Federal Trade Commission (FTC) mandated the addition to Four Loko cans of a label indicating its alcohol content in standard drinks, presented as "alcohol per serving" and "servings per container." OBJECTIVE: The current study investigated whether college students accurately estimate the alcohol content in cans of Four Loko bearing the FTC mandated labels. METHOD: Undergraduate student drinkers (n = 833; 51.6% women) in three states (Florida, Montana, and Virginia) were provided an empty Watermelon Four Loko can and asked to determine the number of standard drinks it contained, using 12-ounce regular beer (Budweiser) equivalents. In Florida and Virginia, Watermelon Four Loko contains 4.70 standard alcoholic drinks; in Montana, it contains 3.13. RESULTS: More than 60% of Florida students and more than 70% of Virginia students underestimated Four Loko's alcohol content by one or more standard drinks, compared to 45% of Montana students. Multivariable logistic regression analysis found the following variables were associated with greater odds of underestimating Four Loko's alcohol content by one or more standard alcoholic drinks: being female (AOR = 2.2), having never seen nor heard of Four Loko (AOR = 1.9), and residing in Florida (AOR = 1.7) or Virginia (AOR = 2.8) versus Montana. CONCLUSIONS: Students were far less likely to underestimate alcohol content for 8% alcohol-by-volume (abv) cans compared to those with higher alcohol concentrations. Thus, policies restricting supersized alcopops' abv may help consumers better estimate their alcohol content.

Drinking, Social Abstaining, and Refusing Invitations: Demographic Differences Persist Across College.

BACKGROUND: Alcohol use and misuse are prevalent on many college campuses. The current study examined participation in college environments where alcohol is present and being consumed. We documented students' alcohol consumption, social abstaining (i.e., attending an alcohol-present event, but not drinking), and refusing invitations to drinking events. We tested for differences by parental education, immigrant status, race-ethnicity, and gender. We charted longitudinal change across college. METHODS: First-year students attending a large public US university (n = 681, 18% first-generation college student, 16% first-generation immigrant, 73% racial-ethnic minority group member, 51% women) were recruited and followed longitudinally for 7 semesters. Each semester, students completed up to 14 daily surveys; responses were aggregated to the semester level (n = 4,267). RESULTS: Multilevel logistic regression models demonstrated that first-generation college students were less likely to drink and refuse invitations to drinking events than students with a college-educated parent (Adjusted Odds Ratios [AORs]: 0.66, 0.72, respectively). Similarly, first-generation immigrants were less likely to drink, socially abstain, and refuse invitations (AORs: 0.58 to 0.73). Compared with White students, Black and Asian American students were less likely to drink (AORs: 0.55, 0.53) and refuse invitations to drinking events (AORs: 0.68, 0.66). The proportion of days spent drinking increased across college, and refusing invitations was the most common at the start and end of college. CONCLUSIONS: First-generation college students, first-generation immigrant students, and Black and Asian students participated less in prodrinking environments during college. These findings indicate that on drinking and nondrinking days, students' participation in alcohol-present situations differed by background. Furthermore, our results indicate that the students who are most likely to refuse invitations to drinking events are the same students who drink most frequently.

Driving/riding after alcohol and marijuana use among young adults: Is residing with family protective?

Objective: Driving while impaired by alcohol or drugs increases the risk of motor vehicle fatalities, the leading cause of death among young adults. The current study documented the prevalence of driving after alcohol and marijuana use in the past 2 weeks as well as the prevalence of riding with a driver who had used each substance during that time frame. We tested whether young adults who lived with family members (i.e., their parents or their children) were less likely to engage in these behaviors. Methods: Participants aged 18-25 who resided in nonmetropolitan areas in the United States (N = 1,131; 55% female, Mage = 22.6) completed an online survey. Multivariate logistic regressions examined alcohol- and marijuana-related driving and riding behaviors adjusting for demographic factors. Interactions tested whether associations varied by gender. Results: In the 2 weeks prior to the survey, 17% of participants drove after drinking alcohol and 21% had ridden with a driver who had been drinking. The prevalence of driving after marijuana use was 11%, and 16% of the sample had ridden with a driver who had been using marijuana. Participants who lived with their parents were less likely to ride with a driver who had been using alcohol or marijuana (adjusted odds ratios [AORs] = 0.71 and 0.55, respectively). Living with parents was also associated negatively with driving after both substances, but these associations were no longer significant when controlling for substance use frequency and driving frequency. Surprisingly, the odds of driving after marijuana use were over 2 times larger for young adults who lived with their children. For women, but not men, residing with children decreased the odds of driving and riding after alcohol use. Conclusions: Living with parents protects against riding after substance use among young adults. Prevention programs should target young adults who live independently or those transitioning away from the parental home. Furthermore, given the higher rates of driving after marijuana use among young adult parents, this group should be educated about the risks associated with this behavior.

Context and culture: Reasons young adults drink and drive in rural America.

Montana, a large and rural U.S. state, has a motor vehicle fatality rate almost double the national average. For young adults, the alcohol-related motor vehicle fatality rate in the state is almost three times the national average. Yet little research has explored the underlying reasons that young people in rural areas drink and drive. Drawing from the theory of triadic influence (TTI) and a series of qualitative focus group discussions, the current study examined how aspects of the landscape and culture of rural America promote and hinder drinking and driving among young people. In 2015 and 2016, 72 young adults (36 females) aged 18-25 years old (mean age = 20.2) participated in 11 semi-structured focus groups in 8 rural counties in Montana. Discussions were transcribed, and two reviewers independently coded text segments. Themes were identified and an inductive explanatory model was created. The results demonstrated that aspects of the social context (e.g., peer pressure and parental modeling), rural cultural values (e.g., independence, stoicism, and social cohesion), and the legal and physical environment (e.g., minimal police presence, sparse population, and no alternative transportation) promoted drinking and driving. The results also identified salient protective factors in each of these domains. Our findings demonstrate the importance of examining underlying distal determinants of drinking and driving. Furthermore, they suggest that future research and interventions should consider the complex ways in which cultural values and environmental factors intersect to shape the risky health behaviors of rural populations.

Immigrant paradox? Generational status, alcohol use, and negative consequences across college.

The current study examined linkages between generational status, alcohol use, wanting to get drunk, and negative alcohol-related consequences during college. We tested whether immigrant students' longitudinal alcohol use trajectories converged to dominant unhealthy patterns or whether immigrant students maintained healthier patterns across college. We also examined if the weekend exerted equal risk for students of different generations. Furthermore, we explored whether patterns were consistent among Latinx and Asian American students. Stratified random sampling identified first-year students attending a US college. A longitudinal daily diary design was used; students completed web-based surveys for up to 14 days within each of 7 semesters. Each day, participants (N = 689; n1st generation = 114; n2nd generation = 244; 51% female) reported their alcohol use and consequences (N = 55,829 days). Multi-level models demonstrated that compared to 3rd generation students, 1st generation students were more likely to abstain from alcohol and less likely to binge drink and want to get drunk. First generation students also experienced fewer negative alcohol-related consequences. The protective effect of being 1st generation was maintained across college semesters, with subgroup analyses focusing on Latinx and Asian American students largely supporting the main findings. However, for abstaining and negative consequences, the weekend effect was less pronounced for immigrants than later generation students. For example, the difference in negative consequences between 1st (vs. 3rd) generation students was largest on the weekend. Additional work is needed to understand how 1st generation students leverage protective factors to abstain from alcohol use even when exposed repeatedly to "wet" drinking environments.

Activities and Situations When Young Adults Drive Drunk in Rural Montana.

OBJECTIVES: This qualitative study explored activities and situations that often result in young adults driving while under the influence of alcohol in rural Montana. METHODS: Eleven focus groups were conducted in 8 rural counties across Montana, and 72 persons (50.7% female, 63.4% college students) aged 18 to 25 years old participated. Focus groups were audio-recorded, transcribed, and narrative text segments were coded independently by 2 researchers. RESULTS: Participants noted a variety of situations specific to rural settings that promoted drunk driving by young adults. Drinking at several types of outdoor activities, such as branding events and festivals, facilitated alcohol consumption in underage youth; drunk driving often followed. Underage youth frequently drank while driving along back roads to avoid detection. Drinking while driving, ie, booze cruising, was thought of as a fun activity and sometimes involved firearms, ie, spotlighting. Driving after drinking was seen as necessary to get home or to other locations. CONCLUSIONS: Our findings should be used to inform multifaceted community-wide programs aimed at reducing underage alcohol consumption as well as deterring driving after/while drinking. Interventions could include media campaigns, improving enforcement of DUI and underage drinking laws, providing alternative transportation, and passing additional alcohol control laws.

Perceptions of driving after marijuana use compared to alcohol use among rural American young adults.

INTRODUCTION AND AIMS: Substance use contributes to motor vehicle crashes, the leading cause of death among young adults. The current qualitative study examined perceptions of the acceptability and harms associated with driving after marijuana versus alcohol use in rural America. Illuminating rural perspectives is critical given that the motor vehicle fatality rate is twice as high in rural as in urban areas in the USA. DESIGN AND METHODS: In 2015-2016, 72 young adults aged 18-25 years (Mage = 20.2; 50.7% female) living in Montana, USA, participated in 11 focus groups. A list of descriptive codes was generated inductively and two individuals coded participant comments. Discussion, memoing and concept mapping were used to uncover broader themes and transcripts were reviewed for evidence of these themes. RESULTS: There was shared consensus that, with regard to crash risk, driving after marijuana use was safer than driving after alcohol use. While alcohol was thought to impair driving ability universally, marijuana's impacts depended on individual characteristics (e.g. compensatory behaviours) and the marijuana itself (e.g. type). Participants expressed conflicting beliefs about policies surrounding marijuana use and driving but were more knowledgeable about alcohol-related policies. Participants viewed older adults and those in frontier areas as more disapproving of driving after marijuana use. DISCUSSION AND CONCLUSIONS: Misinformation about the consequences of driving after marijuana use is common, demonstrating the need for future research and educational interventions. Developing and disseminating guidelines for driving after marijuana use would help marijuana users make informed decisions and mitigate driving-related risks.

Developmental Assets and Risky Sexual Behaviors among American Indian Youth.

This study examined the relationship between developmental assets during early and mid-adolescence and early adult sexual behaviors among American Indians using a subsample from the National Longitudinal Study of Adolescent Health (N = 465). Grounded in an assets framework, the authors explored the protective role of personal, family, school, and community assets as well as cumulative assets for sexual behaviors including early sexual debut, number of sexual partners, and frequency of condom use. The results indicated that certain assets during early and mid-adolescence, such as self-control, family support, and school attachment were protective for various risky sexual behaviors in early adulthood. Furthermore, cumulative assets emerged as an important predictor of sexual behaviors. These findings highlight the utility of applying a developmental asset framework to understand protective factors among American Indian youth.

Academic time during college: Associations with mood, tiredness, and binge drinking across days and semesters.

The current study examined the amount of time American college students spent on academics and explored whether functioning indicators (i.e., positive affect, negative affect, tiredness, and binge drinking) rose and fell with academic time across days and semesters. College students (N = 735) were followed longitudinally and completed 14 daily diaries within each of 7 semesters (N = 56,699 days). The results revealed that academic time decreased slightly during the middle semesters and then increased in later semesters. Furthermore, on days when students spent more time on academics, they reported less positive affect, more tiredness, and less binge drinking; however, the strength and direction of associations depended on the analysis level and whether it was a weekend. Positive affect, for instance, was inversely associated with academics across days, but the reverse was true across semesters. These results emphasize the importance of considering the temporal context in research on adolescent and young adult time use.

Housework time from middle childhood through adolescence: Links to parental work hours and youth adjustment.

The developmental course, family correlates, and adjustment implications of youth housework participation from age 8-18 were examined. Mothers, fathers, and 2 siblings from 201 European American families provided questionnaire and/or daily diary data on 6 occasions across 7 years. Multilevel modeling within an accelerated longitudinal design revealed that girls spent more time on housework than did boys, but that housework time of both girls and boys increased from middle childhood to mid-adolescence and leveled off thereafter. In years when mothers were employed for more hours than usual, girls, but not boys, spent more time on housework than usual. Housework time was linked to more depressive symptoms (at a between-person level) and predicted lower school grades (at a within-person level) for youth with low familism values. Housework time also predicted more depressive symptoms (at a within-person level) for youth with high parent-youth conflict about housework. Findings highlight the gendered nature of housework allocation and the importance of considering both individual and contextual factors when examining youth daily activities.

Revisiting the Time Trade-Off Hypothesis: Work, Organized Activities, and Academics During College.

How adolescents spend their time has long-term implications for their educational, health, and labor market outcomes, yet surprisingly little research has explored the time use of students across days and semesters. The current study used longitudinal daily diary data from a sample of college students attending a large public university in the Northeastern US (n = 726, M age = 18.4) that was followed for 14 days within each of seven semesters (for up to 98 diary days per student). The study had two primary aims. The first aim was to explore demographic correlates of employment time, organized activity time, and academic time. The second aim was to provide a rigorous test of the time trade-off hypothesis, which suggests that students will spend less time on academics when they spend more time on employment and extracurricular activities. The results demonstrated that time use varied by gender, parental education, and race/ethnicity. Furthermore, the results from multi-level models provided some support for the time trade-off hypothesis, although associations varied by the activity type and whether the day was a weekend. More time spent on employment was linked to less time spent on academics across days and semesters whereas organized activities were associated with less time on academics at the daily level only. The negative associations between employment and academics were most pronounced on weekdays. These results suggest that students may balance certain activities across days, whereas other activities may be in competition over longer time frames (i.e., semesters).

Contextual and developmental predictors of sexual initiation timing among Mexican-origin girls.

Using data from a longitudinal study of Mexican-origin girls (ages 11-17 at Time 1), we examined sociocultural (i.e., family structure, nativity, and acculturation), interpersonal (i.e., supportive parenting and conflict), and developmental (i.e., menarche timing and autonomy expectations) predictors of sexual initiation. Using Cox proportional hazards models, we explored whether Time 1 variables predicted the occurrence and timing of first sexual intercourse reported 2.5 and 3.5 years later. Results indicated that the likelihood of early sexual intercourse was higher among first-generation than second-generation immigrants. In addition, living with a stepparent (compared with two biological parents) was associated with a higher likelihood of early intercourse. Furthermore, early autonomy expectations emerged as a salient predictor of intercourse, such that girls with earlier autonomy expectations were more likely to have earlier intercourse than girls with later autonomy expectations. Taken together, results highlight the importance of considering developmental and contextual factors when studying Mexican-origin girls' sexual initiation.

Adult social roles and alcohol use among American Indians.

American Indians are disproportionately burdened by alcohol-related problems. Yet, research exploring predictors of alcohol use among American Indians has been limited by cross-sectional designs and reservation-based samples. Guided by a life course developmental perspective, the current study used a subsample of American Indians (n=927) from the National Longitudinal Study of Adolescent Health (Add Health) to explore alcohol use (current drinking, usual number of drinks, and binge drinking) among this population. We examined whether adult social roles (i.e., cohabitation, marriage, parenthood, college enrollment, and full-time work) were linked to the rise and fall of alcohol use. Multi-level models demonstrated that adult social roles were linked to alcohol use at the within- and between-person levels. Becoming a parent was linked to a lower likelihood of being a current drinker, fewer alcoholic drinks, and less frequent binge drinking. Transitioning to full-time work was associated with a higher likelihood of being a current drinker and more frequent binge drinking. Results point to the importance of exploring within-group trajectories of alcohol use and highlight the protective and risky nature of adult social roles among American Indians.

Family transitions and changes in drinking from adolescence through mid-life.

AIMS: To examine how changes in social roles, particularly in the family, predict rises and falls in alcohol consumption from ages 16 to 50 years. DESIGN: Longitudinal data from the National Child Development Study. SETTING: The birth cohort includes 99% of British infants born in 1 week in 1958. Participants After initial assessment of 17,415 infants, the cohort was interviewed at ages 7, 11, 16, 23, 33, 42, 46, and 50. This study uses the six adolescent to adult waves (n = 7212 women, 7377 men). MEASUREMENTS: Alcohol use [i.e. quantity consumed in past week and heavy daily drinking), symptoms of problem drinking (i.e. Cut-down, Annoyed, Guilt, Eye-opener (CAGE)] and social roles (i.e. union formation, parenthood and employment). FINDINGS: Estimates from fixed-effects models demonstrate that alcohol use is lower when women reside with child(ren) under age 5, compared to occasions when they do not [estimate = -0.38, 95% confidence interval (CI) = -0.43, -0.32 for past week units; odds ratio (OR) = 0.47, CI = 0.36, 0.62 for heavy-daily drinking; OR = 0.66, CI = 0.50, 0.87 for CAGE symptoms]. Associations are similar for men (estimate = -0.29, CI = -0.36, -0.23; OR = 0.64, CI = 0.53, 0.77; OR = 0.69, CI = 0.51, 0.94, respectively). When women and men are married, working and residing with young child(ren), past week units (estimate = -0.51, CI = -0.61, -0.41 for women; estimate = -0.34, CI = -0.44, -0.25 for men), heavy-daily drinking (OR = 0.49, CI = 0.30, 0.79 for women; OR = 0.47, CI = 0.35, 0.64 for men) and CAGE (OR = 0.44, CI = 0.23, 0.83 for women; OR = 0.39, CI = 0.18, 0.82 for men) are lower compared to occasions when they are not in these roles. CONCLUSIONS: From late adolescence to mid-life, women and men in Britain are most at risk for higher levels of alcohol consumption and problem drinking when family roles are absent.

The Link between Mother and Adolescent Substance Use: Intergenerational Findings from the British Cohort Study.

The objective of this study was to identify mother, family, and individual factors associated with adolescent alcohol, tobacco, and marijuana use using mother and child self-reports. Adolescents aged 12-15 (N=276) and their mothers who were participants in the British Cohort Study (BCS; born 1970) were both surveyed when mothers were 34 years old. Predictors included mother's substance use as well as characteristics of the child (gender, age, conduct problems) and family (social class, two-parent family, parent-adolescent conflict). Outcome variables were adolescent alcohol, cigarette, and marijuana use. Child characteristics were predictive, with older children more likely to engage in all behaviors. After controlling for other predictors, mothers' current drinking frequency and problems (i.e., CAGE 1+) predicted adolescent ever and sometimes/regular drinking; mothers' marijuana use was a marginally significant predictor of adolescent marijuana use. Results suggest that mothers' substance use is an important component of adolescent use, even after accounting for characteristics of the child and the intergenerational family context.
