Environmental factors selectively impact co-occurrence of problem/pathological gambling with specific drug-use disorders in male twins.

ABSTRACT:

Aims

Multiple forms of drug abuse/dependence frequently co-occur with problem/pathological gambling (PPG). The current study examines the extent to which genetic and environmental factors contribute to their co-occurrence.

Design

Bivariate models investigated the magnitude and correlation of genetic and environmental contributions to problem/pathological gambling and its co-occurrence with nicotine dependence, cannabis abuse/dependence and stimulant abuse/dependence.

Setting

Computer-assisted telephone interviews in the community.

Participants

Participants were 7869 male twins in the Vietnam Era Twin Registry, a USA-based national twin registry.

Measurements

Life-time DSM-III-R diagnoses for problem/pathological gambling, nicotine dependence, cannabis ab
