About this trial
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.

Trial outcomes
Primary outcomes
1
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.
Time frame
Up to 40 days post-baseline session2
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.
