Sommario breve
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.
Descrizione dettagliata
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 beha...Mostra di più

Esito primario
Misure di esitoDescrizione della misuraArco temporale
Change in self-reported cannabis craving
This study utilizes a structured cannabis cue exposure paradigm. During cue exposure, participants rate subjective craving on a scale from 0, "Not at all," to 10, "Extremely." Cannabis craving will be assessed following neutral cue exposure and then cannabis cue exposure. The primary outcome will be change in cannabis craving.
Up to 40 days post-baseline session
Change in self-reported tobacco craving
This study utilizes a structured tobacco cue exposure paradigm. During cue exposure, participants rate subjective craving on a scale from 0, "Not at all," to 10, "Extremely." Tobacco craving will be assessed following neutral cue exposure and then tobacco cue exposure. The primary outcome will be change in tobacco craving.
