""6508" "Aims? Peer substance involvement (PSI) is a robust correlate of adolescent substance use. A small number of genetically informative studies suggest that shared genetic and environmental factors contribute to this association. We examine mechanisms by which PSI influences the etiology of Etoposide cell line regular substance involvement (RSI), particularly in women. Design? Population-based cohort study of twin women from the US Midwest. Participants? 2176 twin women. Measurements? To examine the relationship between self-reported PSI during adolescence and a composite RSI representing regular tobacco, alcohol and cannabis use during young adulthood, using genetically informative correlation, moderation and joint correlation-moderation models. Findings? There was evidence for a significant additive genetic X environment interaction. PSI was moderately heritable (h2?=?0.25). Genetic, shared and non-shared influences on RSI overlapped with influences on PSI (genetic correlation of 0.43). Even after controlling for these shared genetic influences, RSI was more heritable in those reporting greater PSI. Conclusions? While young women may select peers based on certain dispositional traits (e.g. permissiveness towards substance use), the social milieu constructed by PSI does modify the architecture of increased RSI in those individuals with increasing levels of PSI being associated with stronger expression of heritable influences. ""6509" "Daily smoking rates are decreasing while intermittent or nondaily smoking rates are increasing. Little is known about the association MEK inhibitor of depression, alcohol abuse and dependence, and illicit drug abuse and dependence with different patterns of smoking, particularly nondaily smoking. Thus, we examined these relationships among current smokers versus nonsmokers and among those who smoke daily versus less frequently. We conducted a secondary analysis of 37,897 adults Autophagy who participated in the 2008 National Survey on Drug Use and Health. We developed logistic regression models examining predictors of (i) current smoking and (ii) number of days smoking per month (1�C10 days, 11�C29 days, and ��30 days) among current smokers, focusing on past-year major depression, alcohol abuse and dependence, and illicit drug abuse and dependence. Compared to nonsmokers, current smokers more frequently reported a major depressive episode (p?
