Briefly, findings from twin and family studies suggest common genetic factors shared amongst substance use (r g = 0.14–0.31 for alcohol, tobacco, and cannabis), with stronger estimates of shared genetic overlap amongst measures of problem use (r g = 0.56–0.62; Young, Rhee, Stallings, Corley, & Hewitt, 2006).
