Outcome Measures
Primary Outcomes (1)
Subjective Craving of Marijuana
Defined as the score on the Marijuana Craving Questionnaire (MCQ), range 7-84, higher scores indicate more craving
approx 2.5 hours (before, during and after exposure to stressor condition as well as exposure to neutral and marijuana-associated cues).
Secondary Outcomes (3)
Physiological Assessments: Serum Cortisol, ACTH, BP, HR, and GSR
~ 2.5 hours (before, during and after exposure to stressor condition as well as exposure to neutral and marijuana-associated cues).
Feelings of Stress/Anxiety as Measured by the State-Trait Inventory (STAI)
~2 hours
Current Mood as Assessed by the Mood Form
~2 hours
Study Arms (2)
Stress + cue exposure
EXPERIMENTALIndividuals were exposed to the Trier Social Stress Test (TSST) as well as neutral cues and marijana cues.
No stress + cue exposure
EXPERIMENTALIndividuals were not exposed to a stress test, but were exposed to neutral cues and marijuana cues.
Interventions
Trier Social Stress Task(TSST): subject is asked to give a talk and perform a math task in front of an audience, follwed by neutral and marijuana cue exposure.
Neutral and marijuana-associated cue exposure (scripted imagery, in vivo cues).
