Using Novel Behavioral Economic Measures to Characterize Dual Marijuana and Tobacco Use in Young Adults
Brown University
Summary
The multi session experimental study aims to determine dual use patterns of marijuana and tobacco by assessing the impact of price and availability of marijuana and tobacco using a cross price elasticity of demand task. The study will recruit 120 non-treatment seeking emerging young adults (18-25 years) who smoke marijuana and tobacco.
Description
Young adulthood is a crucial time to study substance use disorders which increase cancer risk later in life. It is especially important to understand marijuana and tobacco use as most young adults often use both. Although dual use is related with increased long-term health and behavioral risks, underlying behavioral mechanisms remain unclear. This study aims to address this gap by using rigorous laboratory-based behavioral economic measure including a novel cross-price elasticity of demand (CPED) task and an innovative extension of cue-induced demand to assess cross-cue reactivity to better un…
