Description
This three-year R01 grant was awarded by NIDA for $953,260 in 2007. Jane Metrik is the Principal Investigator. Co-Investigators include Peter Monti, Damaris Rohsenow, Christopher Kahler, and John McGeary. Despite associations between marijuana use and risk-taking behaviors, controlled research on marijuana’s acute effects on risk taking and impulsivity is limited, and the mechanism whereby marijuana may increase such behaviors has not been established. The primary goal of this experimental research is to examine the independent effects of marijuana pharmacology and expectancies on impulsivity and risk taking and identify individual difference characteristics such as genetic variability that may influence this response. The targeted population is current marijuana smokers (18-30 years old) who are not seeking marijuana treatment. The long-term objective of this program of research is to examine how knowledge gained from cannabis-administration laboratory studies can help develop innovative clinical intervention strategies for marijuana smokers.
