Aims
To estimate the effect of recreational legalization on cannabis use frequency and sources of variance across legal environments.
Design
Longitudinal discordant twin and gene–environment interaction models in twins recruited from birth records and assessed prospectively.
Setting
The United States, including states with different recreational cannabis policies before and after 2014, when recreational...
Eating disorders and substance use disorders frequently co‐occur. Twin studies reveal shared genetic variance between liabilities to eating disorders and substance use, with the strongest associations between symptoms of bulimia nervosa and problem alcohol use (genetic correlation [rg], twin‐based = 0.23‐0.53). We estimated the genetic correlation between eating disorder and substance use and disorder...
Background and aims
Cannabis is one of the most commonly used substances among adolescents and young adults. Earlier age at cannabis initiation is linked to adverse life outcomes, including multi‐substance use and dependence. This study estimated the heritability of age at first cannabis use and identified associations with genetic variants.
Methods
A twin‐based heritability analysis using 8055...
To examine the associations between substance use and antisocial behavior trajectories and seven risky behaviors over time.Data were collected from a high-risk sample of adolescents followed into young adulthood. Five trajectory classes, identified based on dual development of substance use and antisocial behavior symptoms, were used to predict three risky driving and four risky sexual behaviors.In...
