The Customary Drinking and Drug use Record (Brown et al., 1998) collected from the teen detailed information on quantity and frequency of lifetime and past 3-month alcohol, marijuana and other drug use (including misuse of prescription and over-the-counter medications), as well as abuse/dependence, withdrawal, and negative consequences. The Timeline Followback (Sobell and Sobell, 1992) assessed the pattern of substance use during the 28 days preceding the scan session using the youth and parent report (see Tapert et al., 2007). The FTND (Heatherton et al., 1991) indicated that no participant was dependent on nicotine.
