OBJECTIVE A recent Children-of-Female-Twin design suggests that the association between maternal alcohol use disorder and offspring ADHD is due to a combination of genetic and environmental factors, such as prenatal nicotine exposure. We present here a complementary analysis using a Children-of-Male-Twin design examining the association between paternal(More)
BACKGROUND Previous reports in adults have suggested that the effects experienced after cannabis use can be described in terms of positive and negative subtypes that are heritable and are associated with abuse and dependence. This study extends existing research by inclusion of adolescents and young adults in an offspring of twins design which makes it(More)
OBJECTIVE To evaluate the possible association between maternal smoking during pregnancy and offspring outcomes of birth weight, pre-term birth, remediation, low scholastic achievement, regular smoking, attention deficit hyperactivity disorder and conduct problems while controlling for similar behaviors in parents. METHODS Using telephone interviews, data(More)
Not only are alcoholism and externalizing disorders frequently comorbid, they often co-occur in families across generations; for example, paternal alcoholism predicts offspring conduct disorder just as it does offspring alcoholism. To clarify this relationship, the current study examined the 'common genes' hypothesis utilizing a children-of-twins research(More)
OBJECTIVE The alcoholism research literature has long reported a significant, reliable, and inverse association between alcohol use disorders and religion/spirituality (R/S), and this is also evident in the period of highest risk--adolescence and young adulthood. In the treatment area, both clinical and mutual-help programs for alcohol use disorders often(More)
BACKGROUND Nicotine dependence is associated with considerable morbidity and mortality. Two predominant classification systems, the Diagnostic and Statistical Manual (DSM-IV) and Fagerström Test for Nicotine Dependence (FTND), have been used to measure liability to nicotine dependence, yet few studies have attempted to simultaneously examine both sets of(More)
OBJECTIVE Using an offspring-of-twins design, we tested the hypothesis that exposure to paternal alcoholism during the child's first 12 years will increase offspring risk for subsequent alcohol-use disorders (AUD). METHOD Structured psychiatric interviews assessed history of psychiatric and substance-use disorders in Vietnam Era Twin Registry fathers (n =(More)
BACKGROUND Although substance use is associated with reduced educational attainment, this association may be owing to common risk factors such as socioeconomic disadvantage. We tested whether alcohol, nicotine, and illicit drug use and dependence were associated with lifetime educational attainment after controlling for familial background characteristics.(More)
OBJECTIVE The Lifetime Drinking History (LDH) has been used to examine alcohol use throughout the life span. Given its retrospective nature, it is important to examine the validity of the assessment. METHOD Building on previous work establishing the reliability and validity of the LDH, the current study examined a sample of 1,295 men in the Vietnam Era(More)
BACKGROUND While most individuals initiate their use of tobacco prior to onset of cannabis use, recent reports have identified a smaller subset of youth who report onset of cannabis use prior to tobacco use. In this study, we characterize patterns of cannabis and tobacco use (tobacco but not cannabis, cannabis but not tobacco or both) and compare the(More)
