Assessing Associations in Substance Use across Three Generations: From Grandparents to Sons and from Sons to Their Children

Recreational Cannabis Legalization and Proximity to Cannabis Retailers as Risk Factors for Adolescents' Cannabis Use

Within-person studies are lacking regarding how recreational cannabis legalization (RCL) and the numbers of neighborhood cannabis retailers relate to adolescents' cannabis use. Study participants were 146 offspring (55% girls; 77% White non-Latinx) of men recruited in childhood from neighborhoods with high delinquency rates. Youth were assessed for past-year cannabis and alcohol use one or more times from ages 13 to 20 years (age M[SD] = 16.4 [2.1] years across 422 observations), while they were living in Oregon or Washington from 2005 to 2019 (where cannabis retail stores opened to adults ages 21 years and older in 2014 and 2015, respectively). We calculated distances between addresses of licensed cannabis retailers and participants' homes. Multilevel models that accounted for effects of age on cannabis use did not support that the number of retail stores within 2-, 5-, 10-, or 20-mile radii of adolescents' homes increased likelihood of past-year cannabis use at the within- or between-subjects levels. Likewise, primary models did not support a greater likelihood of cannabis use among youth whose adolescence coincided more fully with the post-RCL period. A secondary model suggested that after adjusting for adolescents' concurrent alcohol use as a marker of general substance use risk, RCL was associated with cannabis use (between-subjects B [95% CI] = .35 [.05-.66], p = .024). Further research is needed with larger prospective samples, at-risk subgroups, and as cannabis markets mature.

"I Grew Up Amidst Alcohol and Drugs:" a Qualitative Study on the Lived Experiences of Parental Substance Use Among Adults Who Developed Substance Use Disorders Themselves

Experiencing parental substance use (PSU) has been associated with a heightened risk of developing substance use disorders (SUDs) in offspring. The primary goal of this study was to explore perspectives of adult children with lived experience of PSU who also developed SUDs themselves through first-hand experience. This study was conducted in Flanders (Belgium). A qualitative exploratory research design was applied. Seventeen semi-structured interviews were conducted with adult children of parents with SUDs (range: 29-48 years) who themselves had developed SUDs. All interviews were audio-taped and transcribed verbatim. Three overarching themes emerged through thematic analysis: 1) loneliness and neglect in childhood; 2) stigma and the self; and 3) the role of social connection in substance use and recovery. The narratives highlighted the central role of feelings of loneliness, isolation and belonging among children of parents with SUDs in childhood and adulthood. Increasing public awareness on the impact of PSU on children and accessible support is needed to overcome stigma and remove barriers to social inclusion for children of parents with SUDs. Findings may prove valuable in informing policy, program and treatment development aimed at breaking maladaptive intergenerational cycles.

Intergenerational Associations in Crime for an At-Risk Sample of US Men: Factors that May Mitigate or Exacerbate Transmission

PURPOSE

To examine moderation of intergenerational transmission of crime and antisocial behavior of parents to adult arrests of sons (from age 18 years to ages 37-38 years). Moderators examined were from late childhood (constructive parenting and sons' inhibitory control, internalizing symptoms, and cognitive function), adolescence (delinquency and deviant peer association), and early adulthood (educational achievement, employment history, substance use, deviant peer association, and partner antisocial behavior).

METHODS

Study participants were parents and sons (N = 206) from the longitudinal Oregon Youth Study, recruited from schools in the higher crime areas of a medium-sized metropolitan region in the Pacific Northwest. Assessment included official arrest records, school data, interviews, and questionnaires.

RESULTS

As hypothesized, parents' and sons' histories of two or more arrests were significantly associated. Predictions of sons' arrests from a broader construct of parental antisocial behavior were significantly moderated by sons' late childhood cognitive function and early adult employment history, substance use, and romantic partner's antisocial behavior. Overall, there was relatively little intergenerational association in crime at low levels of these moderators.

CONCLUSIONS

Findings indicate relatively large intergenerational associations in crime. The identified moderators may be used as selection criteria or targeted in prevention and treatment efforts aimed at reducing such associations.

The intergenerational transmission of harsh parenting, substance use, and emotional distress: Impact on the third-generation child

The current study evaluated the intergenerational transmission of harsh parenting, substance use, and emotional distress across generations and the association with child aggression. The study included 218 Generation 1 (G1) mothers and fathers, their adolescent (Generation 2; G2) who participated from middle adolescence through adulthood, and the 3rd-generation (G3) child between ages 3-5 years and 6-10 years. G1 behavior was examined when G2 was 16 and 18 years old; G2 alcohol problems and marijuana use were assessed when G2 was 19 and 21 years old. G2 emotional distress and harsh parenting were examined when the G3 child was between 3 and 5 years old. Finally, G3 aggression was assessed between 6 and 10 years old. Results showed continuity of G1 behavior when G2 was in adolescence to G2 behavior in adulthood. G1 alcohol problems and G1 harsh parenting were both associated with G3 aggression through G2 alcohol problems, G2 emotional distress, and G2 harsh parenting. Results suggest that G1 problem behavior as experienced by G2 adolescents in the family of origin plays an important role in G2 alcohol problems in emerging adulthood, which leads to G2 emotional distress and G2 harsh parenting in adulthood, which is related to G3 aggression in the early elementary school years.

Intergenerational associations in onset of cannabis use during adolescence: A data synthesis approach

The present study examined associations between parents' and their children's ages of onset of cannabis use using a data synthesis methodology to pool data from 3 similarly designed intergenerational studies. Regarding age of first use of cannabis, prospective data were collected at one or more assessments from early to late adolescence in each generation. The extent to which parent and offspring gender separately or jointly moderated intergenerational effects was examined. Data were harmonized from studies originating in the states of Washington (Bailey, Hill, Epstein, Steeger, & Hawkins, 2018), New York (Thornberry, Henry, Krohn, Lizotte, & Nadel, 2018), and Oregon (Capaldi, Kerr, & Tiberio, 2018) when the parents were in late childhood to early adolescence; analyses concerned 1,081 parents and their children from 971 unique families. Parents' and their children's age of cannabis use onset during adolescence were modeled using discrete-time survival analysis techniques. Although data were successfully synthesized across the studies, the primary hypothesis was not supported: parents' earlier age of first cannabis use during adolescence was not significantly associated with earlier onset of cannabis use in the offspring generation. Rather, parents' histories of any cannabis use in adolescence-regardless of timing-were linked with increased risk for early onset cannabis use by their children compared to parents with no history of use during adolescence. There were no significant parent, child, or parent-by-child gender moderation effects. Thus, prevention of adolescent onset of cannabis in one generation may have prevention benefits for the next.

Men's misuse of prescription opioids from early to middle adulthood: An examination of developmental and concurrent prediction models

OBJECTIVE

The prevalence of misuse of prescription opioids across adulthood and the associations of such misuse with symptoms of psychopathology and use of other substances were examined for an at-risk community sample of men.

METHOD

For a longitudinal study of boys (N = 206) followed to adulthood, misuse of prescription opioids was assessed on 13 occasions from ages 20-21 years to 37-38 years. Prediction of misuse was examined from prospectively assessed risk factors in 3 models: (a) parental substance use during the men's adolescence; (b) the men's own risk behaviors in adolescence-delinquent behavior, depressive symptoms, and use of tobacco, alcohol, marijuana, and opioids; and (c) within- and between-individual effects of the men's risk behaviors during adulthood.

RESULTS

Opioid misuse was reported by 29% of men. After accounting for effects of age and considered individually, parent marijuana use and all of the adolescent and adult risk factors (except adolescent depressive symptoms) were significant between-individual predictors of opioid misuse. Furthermore, within-individual prediction was significant for adult delinquency and alcohol use after accounting for increases in opioid misuse with age. When risk factors were tested simultaneously, men's adult delinquency and use of marijuana and tobacco remained significant between-individual predictors, whereas no parental or adolescent risk factors remained significant in these models.

CONCLUSION

Both adolescent and adult risk factors were examined that predicted adult opioid misuse. Preventing adolescent problem behavior and using such histories to inform screening for misuse risk in adulthood may reduce the burden of the opioid crisis.
