Parental cannabis use disorder (CUD) and low positive parenting (monitoring, support, and consistency) are risk factors for adolescent cannabis use. However, it is unclear whether parental cannabis use without CUD is sufficient to increase risk for low positive parenting and adolescent cannabis use. Additionally, parents may not treat each of their adolescents the same, and risk for adolescent cannabis use may increase as a result of low levels of positive parenting in families or low positive parenting unique to each adolescent. The current study prospectively tested low positive parenting as a mediator of the relation between parental cannabis use history (with parental cannabis use and CUD considered separately) and adolescent cannabis use at the family level and individual level. Participants were 363 adolescents from a multigenerational longitudinal study who reported on positive parenting when they were ages 9-16 (M = 11.6, SD = 1.40) and on cannabis use when they were ages 13-19 (M = 16.3, SD = 1.84). Parents reported on their own cannabis use and CUD. Results showed that parental CUD was associated with adolescent cannabis use (OR = 3.62, p = .047) but parental cannabis use without CUD was not, and only parental CUD predicted low positive parenting (B = -0.28, p < .05). Average levels of low positive parenting within a family partially mediated the association between parental CUD and offspring cannabis use. These findings suggest parental cannabis use alone may not impair parenting, but parental use that meets criteria for CUD does impair parenting. Additionally, average levels of positive parenting in families may be a mechanism underlying the intergenerational transmission of cannabis use. (PsycINFO Database Record

Adolescent cannabis use is common, has been associated with several deleterious outcomes, and is often associated with previous parent cannabis use. Therefore, identifying protective factors that prevent this intergenerational transmission of cannabis use is increasingly important given shifting contemporary policies around cannabis use. The present study examines 3 protective factors in adolescence (active coping, positive activity involvement, and school grades) that may disrupt patterns of intergenerational cannabis use. The present study uses data from a high-risk longitudinal sample followed for over 30 years that includes Generation 1 (G1) parents (54.19% with lifetime alcohol use disorder, 8.15% with lifetime cannabis use disorder), their Generation 2 (G2) children, and their Generation 3 (G3) grandchildren and therefore provides the opportunity to replicate effects across 2 intergenerational cohorts (a G1-G2 cohort and a G2-G3 cohort). Results from ordered logistic regression models reveal that in both intergenerational cohorts, greater midadolescent active coping, higher positive activity involvement, and higher grades prospectively predict lower late adolescent cannabis use at significant (p Ͻ .05) or marginal (p Ͻ .10) levels, even after powerful control variables, such as parent cannabis use and alcohol use, as well as previous early adolescent cannabis use, are accounted for. Additionally, in both intergenerational cohorts, midadolescent high levels of active coping disrupt intergenerational transmission of cannabis use. Results indicate replication in the intergenerational transmission of cannabis use and in the protective effects of coping, grades, and, to a lesser extent, positive activity involvement across generational cohorts. Implications for prevention programming are discussed.

Background: Parental drinking and parent alcohol use disorder (AUD) are known predictors of adolescent positive alcohol expectancies, but their link to negative expectancies is unclear. Research suggests that parent drinking may indirectly predict adolescent expectancies through exposure to parental drinking events. However, exposure to parent negative alcohol consequences may be more relevant to adolescents' expectancies. The present study tested the mediating effect of parent observable negative alcohol consequences in the association between parent AUD and adolescent expectancies.Methods: This study used parent and adolescent data from the Adult and Family Development Project. A total of 581 adolescents reported on their alcohol expectancies across 2 waves of data, and their parents reported on potentially observable alcohol-related negative consequences during the first wave. Past-year and lifetime parent AUD were assessed with diagnostic interviews across 6 waves of data.Results: Mothers' observable consequences mediated the effect of her past-year AUD on adolescent negative expectancies in adolescence, but this effect did not hold at a 1.5-year follow-up. Mothers' lifetime AUD was the only prospective predictor of later adolescent negative expectancies. No father drinking variables predicted expectancies, and all models were invariant across child biological sex. Finally, older adolescent age prospectively predicted higher positive expectancies, whereas the adolescents' own drinking predicted lower negative expectancies.Conclusions: These findings, in line with other recent studies, suggest that exposure to mothers' negative experiences with alcohol may counterintuitively normalize negative alcohol effects. This may paradoxically increase risk for adolescents rather than buffering the effects of a family history of parental AUD.

Adolescent alcohol use is related to disinhibition traits and family environments. However, research is scarce on whether these factors predict alcohol use trajectories distally, from early adolescence into early adulthood. We examined whether sensation seeking and parenting environments in early adolescence predicted adolescents' alcohol use trajectories proximally (middle-adolescence) and distally (early adulthood). Using four waves of data from 345 adolescents (51.3% female; 80% white) and their primary caregivers, we estimated adolescents' alcohol use trajectories and examined variability in these by sensation seeking and parental control. The findings revealed distal, positive associations between sensation seeking and alcohol use; and negative, proximal associations between parental control and alcohol use. Also proximally, there was a significant interaction between sensation seeking and parental control. We discuss implications for theory and practice.

Findings suggest that the developmental period in which parents' recovery occurs is a useful way to categorize "recovered" AUDs versus current AUDs.
