Predictors of marijuana use among married couples: the influence of one's spouse

With the transition into marriage, marijuana and other substance use tends to decline; however, this is not true for all individuals. The objective of this work was to examine the impact of premarital individual and partner psychological health and substance use behaviors on the likelihood of using marijuana over the first four years of marriage. Couples' (N=634) marijuana use, other substance use, and psychological variables were assessed at the time they applied for their marriage license and then again at the first, second and fourth anniversaries. Generalized estimating equation models were used to estimate the risk for using marijuana over the first four years of marriage after controlling for the natural decrease in risk associated with time and other relevant sociodemographic variables. Smoking prior to marriage and heavy alcohol use was associated with an increased risk for using marijuana over the first four years of marriage for both husbands and wives. After considering the impact of time and individual risk factors, a spouse's use of marijuana prior to marriage was a strong predictor of increased risk for marijuana use during the first four years of marriage.     

Peer networks among heavy, regular and infrequent drinkers prior to marriage

OBJECTIVE: Research has consistently demonstrated that, among adolescents, the characteristics of one's peers are important predictors of substance abuse. The impact of the peer network on adult drinking, however, has received considerably less attention. The purpose of the present study was to examine social network characteristics that are associated with heavy drinking in adulthood prior to marriage. METHOD: Couples were recruited at the time of their first marriage. Husbands and wives were each given identical questionnaire packets to complete at home, independently, as well as a postage-paid envelope for packet return. A broad range of constructs was assessed; included were personality characteristics, relationship functioning, drinking behavior and social network characteristics. Complete data were obtained from 471 husbands and 471 wives. RESULTS: The social networks of heavy-drinking men, compared to men drinking regularly or infrequently, were younger, more likely to be male and unmarried and consisted of friends rather than family or others. For both men and women, "drinking buddies" accounted for nearly 75% of the heavy drinkers' peer networks. The overall ratings of support and conflict created by peers did not differ according to drinking group, for either men or women. CONCLUSIONS: Prior to marriage, the social networks of heavy drinkers differ considerably from the networks of regular or infrequent drinkers with regard to the drinking patterns of their peers. An important finding was that heavy drinkers appear to experience a similar level of emotional, financial and practical support from their peer network compared to regular or infrequent drinkers.     

Illicit drug use and marital satisfaction

With the acquisition of adult social roles such as marriage, more deviant or socially disapproved behaviors such as drug use often decrease. The objective of this work was to examine patterns of illicit drug use in a community sample of adults during the transition and early years of marriage. Additionally, this work examined if couples who were discrepant in their drug use (i.e., one individual reported past year drug use and the partner reported no use) experience sharper declines in marital satisfaction compared to other couples. Multilevel regression models explored these issues over the first four years of marriage (N=634 couples). Although rates of illicit drug use decline over the first four years of marriage, a significant number of husbands and wives continued to use illicit drugs (21% and 16%, respectively). At the transition to marriage, both husbands and wives who had discrepant drug use behaviors experienced lower levels of marital satisfaction compared to other couples. Over the first four years of marriage, couples in each group experienced significant declines in marital satisfaction.     

Emerging adulthood themes,role transitions and substance use among Hispanics in Southern California

Introduction

Hispanic emerging adults appear to be at especially high risk for substance use but little is known about their risk and protective factors. A crucial next step to reducing substance use among this priority population may involve understanding how transition-to-adulthood themes are associated with substance use. Intervention and prevention programs could also benefit from information about which if any specific transitions undergone in emerging adulthood are associated with substance use.

Methods

Hispanic emerging adults (aged 18 to 24) completed surveys indicating their identification with transition-to-adulthood themes, role transitions in the past year, and use of alcohol and marijuana. Logistic regression models were used to examine the associations between transition-to-adulthood themes and past-month binge drinking and marijuana use, controlling for age and gender. Separate logistic regression models explored the association between each individual role transition and past-month binge drinking and marijuana use, controlling for age and gender and using a Bonferonni correction.

Results

Among the participants (n = 1,390), 41% were male, the average age was 21, 24% reported past-month marijuana use and 34% reported past-month binge drinking. Participants who felt emerging adulthood was a time of focusing on others were less likely to report marijuana use and binge drinking. Among the 24 transitions, five were significantly associated with past-month marijuana use and 10 were significantly associated with past-month binge drinking.

Conclusion

Findings suggest transition-to-adulthood themes as well as specific changes experienced by emerging adults are meaningful for Hispanics and should be explored in prevention and intervention programs in the future. Future research should determine what specific mechanisms are making these transitional processes risk factors for substance use.     

Racial bullying and adolescent substance use: An examination of school-attending young adolescents in the United States

This article examines the association between race and racial bullying (bullying due to one's race), in relation to youth substance use in school attending young adolescents in the United States. Weighted unadjusted and adjusted logistic regression models were run to assess if racial bullying involvement was associated with youth substance use. Data for this study come from the Health Behaviors in School-Aged Children survey (n = 7,585). An association between racial bullying status (not involve, bullying victim, bullying perpetrator, or mixed bullying victim/perpetrator) and youth substance was identified in this study. Racial bully perpetrators were most likely to have used cigarettes, alcohol, and marijuana, followed by youth in the mixed victim/perpetrator group. When analyses were stratified by race, non-Hispanic White and Hispanic youth experienced an increased risk of cigarette, alcohol, and marijuana use if in the perpetrator or mixed group (compared to those not involved with racial bullying). Non-Hispanic White and Asian youth were also more likely to report marijuana use if in the victim group. Non-Hispanic Black youth were more likely to use alcohol and marijuana if they were a perpetrator or in the mixed group, but they were not more likely to use cigarettes. Differences appear to exist in relation to racial bullying experience and substance across racial/ethnic group among youth in grades 7–10. Implications for prevention and educational professionals are discussed.     

Age-related differences in adolescent smokers' and nonsmokers' assessments of the relative addictiveness and health harmfulness of cigarettes, alcohol, and marijuana

The present work was undertaken to determine how general beliefs about various substances and substance use behaviors change during adolescence. Secondary analyses were carried out on the telephone interview responses of 1,200 adolescent smokers and nonsmokers between the ages of 12 and 17. The specific beliefs regarding which substances were hardest to stop using and which were the most harmful to one's health by smoking status and age were compared using Chi-squared analyses for univariate comparisons, and polytomous logistic regression for multivariate analyses. Results revealed that the youngest cohort believed that marijuana was the substance most difficult to stop using while the oldest cohort believed that cigarettes were the hardest to stop using. A similar pattern was observed regarding which substance was the most harmful to one's health. While smokers believed that cigarettes were both the hardest to stop using and the most harmful, nonsmokers were divided between cigarettes and marijuana as the hardest to stop using, and indicated that marijuana, rather than cigarettes, were most harmful. Results are discussed in terms of their implications for substance abuse prevention and the development of relative risk assessments.     

Marital History of Narcotics Addicts

About twice as many as expected of the male subjects never married. The more striking fact about the marital histories, however, is that both men and women had multiple marriages much more often than the base Kentucky population. Marriages were likely to end in divorce or separation. Subjects had only about two-thirds the number of children that would have been expected.

Data were collected on four kinds of deviant behavior in the spouses of subjects—narcotics use, alcoholism, prison record, and mental illness. The total number of deviant spouses and the number of user spouses were so much beyond chance expectancy as to establish that some selective factors must have been operating. Five hypotheses were suggested to account for the frequency of narcotics use and other deviance in spouses. Some support was found for all, but in each case the pattern for female subjects was found to differ from that for the males.

In general, male subjects showed a slight tendency to select users or otherwise deviant women as wives but a moderately strong tendency to make their wives deviant, especially in the form of narcotics use, after marriage. Female subjects showed a marked tendency to select user or otherwise deviant men as husbands; the non-deviants they married became deviant fairly often, but not users.

Male subjects had as many as two deviant wives in very few cases, and multiple marriages increased the probability of having a deviant wife only in proportion to the number of marriages. But women with a deviant husband tended to have more than one, and the men they married were much more likely to be deviant if it was a third or later marriage than if it was a first or second marriage for the woman.

With reference to narcotics use in the spouse, those male subjects who had such a wife differed little from those with no user wife. What difference existed seems to have been somewhat greater involvement in a deviant subculture for those with user wives. The female subjects with user husbands, on the other hand, differed markedly from those with no such husband, and the difference is clearly associated with greater involvement in the drug and criminal subcultures. Men involved in a deviant subculture were somewhat more likely than others to choose a deviant woman as wife, but their choice was clearly not restricted to such women, and many married non-deviants. But women involved in the same subculture chose deviant men as husbands so consistently as to suggest that their choice was largely restricted to these men.

The data clearly and consistently indicate that the transmission of narcotics use in marriage was from husband to wife much more often than from wife to husband. There is also a suggestion, but no more, that when transmission was from wife to husband this represented a conscious act of making the man an addict, for utilitarian reasons—though in these cases the man was clearly deviant before his use of narcotics and the use was but a short step further along a familiar road. When transmission was from husband to wife, the drugs were said to be given for illness or pain, with no suggestion of intended benefit for the giver.

This difference, however, may establish little more than the readiness of informants to attribute any evil to women who were unmistakably labelled as deviants. Perhaps the more interesting finding is that in most cases where both husband and wife were users, all subjects and other informants insisted that they became users independently, or refrained from assigning the responsibility to one of them. Addicts, more ready than most people to admit to disapproved actions, rarely admit to making an addict of another person.     

Evaluating alcohol and marijuana use among emerging adult males via analysis of text messages

Background: Advances in social technologies offer new tools for large scale data collection and analysis of peer influence and social networks on substance use attitudes and behaviors. Objective: The objective of this study was to determine if text message content can predict alcohol and marijuana use attitudes and behaviors. Methods: Text messages from 91 males ages 18–25 were monitored over a period of 6 months and examined for content related to alcohol and marijuana. Self-report data indicating alcohol and marijuana use attitudes and behaviors were used to determine relationships between text message content, social network structure, and substance use attitudes and behaviors. Results: In total, 23,173 text messages were analyzed with 166 text messages including alcohol related terms and 195 text messages including drug related terms. Individuals who sent text messages related to alcohol use were more likely to have problem alcohol use and positive attitudes toward alcohol use, and individuals who sent text messages related to marijuana use reported higher frequency of marijuana use and more positive attitudes toward marijuana use. Individuals with multiple daily marijuana use were in positions that had less control over network structure. Conclusions: The results of this study indicate that monitoring text message content and social network structure among emerging adult males can potentially predict alcohol and marijuana use attitudes and behaviors. Text message content analysis is a novel technique increasing our understanding of the role of peer influence and social network on substance use attitudes and behaviors.     

Psychosocial determinants of marijuana use among African American youth

This study examines the psychosocial determinants of marijuana use among youth. A total of 7,488 African American middle and high school students from 133 metropolitan private and public schools completed a survey assessing psychosocial factors associated with annual marijuana use. The PRIDE survey, a nationally recognized survey on substance use, was used to assess the frequency of marijuana use and the influence of psychosocial factors on marijuana use among African American students. Results indicated that 18.5% of African American youth used marijuana in the past year. Males were significantly more likely than females to report using marijuana. Engaging in risky behaviors, such as getting in trouble at school and with police and attending a party with alcohol and other drugs, were significantly correlated with annual marijuana use. Conversely, having multiple parent, teacher, and school protective factors reduced annual marijuana use in this population. Such findings may assist prevention specialists in developing interventions to reduce and prevent marijuana use.     

Contingent reinforcement of marijuana abstinence among individuals with serious mental illness: a feasibility study

The feasibility of using monetary incentives to promote abstinence from marijuana use among individuals with serious mental illness was examined by using a within-subjects experimental design. Participants were 18 adults with schizophrenia or other serious mental illness who reported regular marijuana use. During 2 baseline conditions, participants received payment for submitting urine specimens independent of urinalysis results. During 3 incentive conditions, participants received varying amounts of money if urinalysis results were negative for recent marijuana use. The number of marijuana-negative specimens obtained was significantly greater during incentive than baseline conditions. These results provide evidence that marijuana use among at least some mentally ill individuals is sensitive to contingent reinforcement and support the potential feasibility of using contingency-management interventions to reduce substance abuse among the mentally ill.     

Personal strivings and marijuana use initiation,frequency, and problems

This study examined relations between perceived conflict/utility of marijuana use in achieving valued personal goals and marijuana use initiation, marijuana use frequency, and marijuana-related problems. Personal strivings are higher order goals that may influence marijuana use to the extent that they are congruent or incongruent with use. Participants were 592 young adults who generated lists of personal strivings independent of the substance use assessment. They then evaluated their 10 most important strivings with regard to the perceived conflict/utility of several levels of marijuana use in achieving their most important strivings. Less marijuana use-striving conflict was positively associated with use initiation and frequency. A significant gender interaction emerged in the prediction of use frequency; marijuana use-striving conflict was more strongly associated with use frequency for men than women. The relationship between use-striving conflict and marijuana-related problems was mediated fully by use frequency.     

An Examination of Multiple Substance Use Between African American and Caucasian Female College Students

Abstract

This study examined the use of alcohol, tobacco, marijuana, and cocaine among 445 African American and Caucasian female college students. Using the Core Alcohol and Drug Survey, the authors explored: (1) the extent of substance use; and (2) whether or not African American female college students were more or less likely to engage in the use of these substances compared to their Caucasian counterparts. Results indicated that alcohol was the most frequently used substance, with more than 73% of the participants reporting alcohol use. The second most commonly used drug was tobacco followed by marijuana; however, only one-fourth of the participants reported using these substances. Cocaine was the least frequently used substance, with less than 2% of the participants reporting the use of this substance. Results also indicated that Caucasian female college students were more likely to engage in the use of alcohol and tobacco than are African American female college students.     

Sexual Minority Disparities in Substance Use Willingness Among Youth

Background: Disparities in substance use have been observed in sexual minority youth, but less is known about willingness to use substances, an important precursor to actual use. Objective: The goal of this study was to examine willingness to use cigarettes, alcohol, and marijuana among sexual minority youth compared to their non-sexual minority counterparts using both cross-sectional and longitudinal data. Methods: The present study drew on two waves (Times 1 and 2; 6 months apart) of data collected during high school as part of a prospective study of substance use initiation and progression in Rhode Island. At Time 1, participants (N = 443) ranged in age from 15 to 20 years (M age = 16.7 years, 26.6% sexual minority, 59.5% female, 72.0% White). Participants self-reported their sexual identity and attraction, lifetime use of alcohol, cigarettes and marijuana, and cigarette, alcohol, and marijuana use willingness (i.e., if offered by a best friend or group of friends). Results: In cross-sectional multivariate regression models, sexual minority youth were more likely to report willingness to use cigarettes (p <.05) and marijuana (p <.01) compared to their non-sexual minority counterparts. Longitudinal multivariate regression models revealed that sexual minorities were only significantly more likely to report cigarette willingness at Time 2 compared to their non-sexual minority counterparts (p <.01). There were no significant differences in alcohol use willingness in multivariable cross-sectional or longitudinal models by sexual minority status. Conclusions: Sexual minority youth reported more willingness than non-sexual minority youth to use substances offered by peers; however, longitudinal analyses revealed that peers appear to play a role only in willingness to smoke cigarettes for these youth, and thus peer influence may be a contributing factor in explaining tobacco-related disparities among sexual minority youth. Given that stigma and peer groups may a particular risk factor for tobacco among sexual minority youth, our findings highlight the importance of prevention programs such as social marketing approaches that correct social norms, reduce stigma, and provide refusal-skills training to reduce tobacco-related disparities among sexual minorities.     

African–American Women’s Tobacco and Marijuana Use: The Effects of Social Context and Substance Use Perceptions

Background: Despite the status of tobacco and marijuana as two of the most commonly used substances in the U.S., both have detrimental health and social consequences for disfranchized African–Americans. Substance use may be shaped by social contextual influences from families and peers in African–American communities, and little research has examined perceptions of wrongfulness, harms, and dangers associated with daily tobacco and marijuana use among African–American women. Objectives: This study explores the effects of African–American women’s social context and substance use perceptions (wrongfulness/harmfulness/dangerousness) on daily tobacco and marijuana use. Methods: Survey data was collected in-person from 521 African–American women. Multivariate logistic models identified the significant correlates of women’s daily use of tobacco and marijuana in the past six months. Results: 52.59% of participants reported daily tobacco use and 10.56% used marijuana daily. Multivariate models indicated that women were more likely to be daily tobacco users if they had a family member with a substance use problem or perceived tobacco use to be wrong, harmful, or more dangerous than marijuana. In the models with marijuana as the dependent variable, women who lived with a person who used drugs were more likely to use marijuana daily. Perceiving marijuana use as wrong or harmful to one’s health was protective against daily marijuana use. Conclusions: Findings stress the need for prevention and intervention efforts for African–American women that highlight social context influences and promote greater awareness of the health risks associated with daily tobacco and marijuana use.     

Weekly Marijuana Use as a Risk Factor for Initial Cocaine Use:

The gateway hypothesis argues that most adolescents begin experimenting with cigarettes or alcohol, progress to marijuana use and finally to other illicit substance use. Prior research has supported this hypothesis, although prior research has not examined the effects of weekly marijuana use on specific illicit substances such as cocaine and has not attempted to identify psychosocial mediators of predictive relationships among substances. The current study uses longitudinal national survey data with six assessment periods and a comprehensive set of psychosocial risk factors for substance use to examine relationships between cocaine and marijuana use using discrete-time survival analysis for multiwave longitudinal data. The results of the current study show that weekly marijuana use, as opposed to initial marijuana use, is an independent risk factor for initial cocaine use. Weekly marijuana users were over ten times more likely to initiate cocaine within the next year. The results also show that many psychosocial predictors are not predictive of initial cocaine use after controlling for prior weekly marijuana use. However, the association between weekly marijuana use and cocaine use is, in part, mediated by delinquent attitudes. We conclude that weekly marijuana use is a risk factor for cocaine use that is equal to or greater in magnitude than other risk factors for initial cocaine use such as deviant peer bonding and attitudes toward deviance. These findings argue for some revision of the gateway hypothesis and psychosocial theories of substance use. In addition, the current research shows support for clinical observations which suggest that regular use of any illicit substance is likely to spawn experimentation with other illicit substances.     

Expectancies and self-efficacy mediate the effects of impulsivity on marijuana use outcomes: an application of the acquired preparedness model

This study tests the acquired preparedness model (APM) to explain associations among trait impulsivity, social learning principles, and marijuana use outcomes in a community sample of female marijuana users. The APM states that individuals with high-risk dispositions are more likely to acquire certain types of learning that, in turn, instigate problematic substance use behaviors. In this study, three domains of psychosocial learning were tested: positive and negative marijuana use expectancies, and marijuana refusal self-efficacy. Participants were 332 community-recruited women aged 18-24 enrolled in a study of motivational interviewing for marijuana use reduction. The present analysis is based on participant self-reports of their impulsivity, marijuana use expectancies, marijuana refusal self-efficacy, marijuana use frequency, marijuana use-related problems, and marijuana dependence. In this sample, impulsivity was significantly associated with marijuana use frequency, marijuana-related problems, and marijuana dependence. Results also indicate that the effect of impulsivity on all three marijuana outcomes was fully mediated by the three principles of psychosocial learning tested in the model, namely, positive and negative marijuana expectancies, and marijuana refusal self-efficacy. These findings lend support to the APM as it relates to marijuana use. In particular, they extend the applicability of the theory to include marijuana refusal self-efficacy, suggesting that, among high-impulsives, those who lack appropriate strategies to resist the temptation to use marijuana are more likely to exhibit more frequent marijuana use and use-related negative consequences.     

Prevalence of marijuana and other substance use before and after Washington State's change from legal medical marijuana to legal medical and nonmedical marijuana: Cohort comparisons in a sample of adolescents

ABSTRACT

Background: A growing number of states have new legislation extending prior legalization of medical marijuana by allowing nonmedical marijuana use for adults. The potential influence of this change in legislation on adolescent marijuana and other substance use (e.g., spillover or substitution effects) is uncertain. We capitalize on an ongoing study to explore the prevalence of marijuana and other substance use in 2 cohorts of adolescents who experienced the nonmedical marijuana law change in Washington State at different ages. Methods: Participants were 8th graders enrolled in targeted Tacoma, Washington public schools and recruited in 2 consecutive annual cohorts. The analysis sample was 238 students who completed a baseline survey in the 8th grade and a follow-up survey after the 9th grade. Between the 2 assessments, the second cohort experienced the Washington State nonmedical marijuana law change, whereas the first cohort did not. Self-report survey data on lifetime and past-month marijuana, cigarette, and alcohol use were collected. Results: Multivariate multilevel modeling showed that cohort differences in the likelihood of marijuana use were significantly different from those for cigarette and alcohol use at follow-up (adjusting for baseline substance initiation). Marijuana use was higher for the second cohort than the first cohort, but this difference was not statistically significant. Rates of cigarette and alcohol use were slightly lower in the second cohort than in the first cohort. Conclusions: This exploratory study found that marijuana use was more prevalent among teens shortly after the transition from medical marijuana legalization only to medical and nonmedical marijuana legalization, although the difference between cohorts was not statistically significant. The findings also provided some evidence of substitution effects. The analytic technique used here may be useful for examining potential long-term effects of nonmedical marijuana laws on adolescent marijuana use and substitution or spillover effects in future studies.     

Substance use off and on school grounds: A California statewide comparison between different groups of homeless students and nonhomeless students

About 1.3 million homeless students attend schools across the US, yet little is known about their substance use patterns, especially substance use on school grounds. The objectives of this study were to examine differences in substance use on and off school grounds between nonsheltered homeless, sheltered homeless, and nonhomeless public school students, and to examine the relationship between homelessness and substance use in school. Data were from a statewide representative sample from the California Healthy Kids Survey collected in 2011–2013, (n = 390,028). Bivariate and multivariate analyses were applied. Findings show that compared to nonhomeless students, homeless students, both sheltered and nonsheltered, reported higher rates of age at first time of use under the age of 10, and recent substance use, for an array of substances, indulging alcohol, cigarettes, marijuana and other illegal drugs. Additionally about 50% of nonsheltered homeless students, and 15% of sheltered homeless students reported having used substances in school in the past 30 days. Results from logistic regressions indicate that homelessness is associated with substance use in school. Particularly, nonsheltered homeless students were 17.41, 12.09, 11.36 and 17.59 times more likely to report smoking cigarettes, drinking alcohol, using marijuana and using other illegal drugs (respectively) in school in the past 30 days, compared to nonhomeless students. Sheltered homeless students were also more likely to use substances in school compared to nonhomeless students, but less likely compared to nonsheltered students. Findings highlight the need to develop differentiated school-based responses to each homeless subgroup and have conceptual, scientific and policy implications.     

Self-control and jail inmates' substance misuse post-release: mediation by friends' substance use and moderation by age

Objective

This study examined the relationship between two risk factors for substance misuse (self-control, substance using friends) and changes in jail inmates' substance misuse from pre-incarceration to post-release.

Method

Participants were 485 adult jail inmates held on a felony conviction, recruited from a metropolitan county-jail situated in the mid-Atlantic region of the U.S. During incarceration, participants completed self-report assessments of pre-incarceration substance misuse and self-control. At one-year post-release, participants reported their substance misuse and proportion of substance-using friends (n = 322 at follow-up).

Results

The relationship between self-control and changes in inmates' substance misuse was fully mediated by association with substance-using friends. Age moderated the relationship between friends' substance use and changes in inmates' own misuse of marijuana and cocaine. Friends' use was more strongly related to marijuana misuse for younger adults than for older adults. However, for cocaine misuse, this relationship was stronger for older adults than for younger adults. Self-control's relationships with other variables were not moderated by age.

Conclusions

This study underscores importance of self-control's indirect relationship (through substance-using friends) with changes in substance misuse: inmates with lower self-control were more likely to associate with substance-using friends and, in turn, had more symptoms of substance misuse 1-year post release. Results emphasize the importance of considering adult substance-users' friend-relationships. However, age and type of substance appear important when considering the relative importance of friends' influence.
