What researchers measure

Primary outcomes

  1. fMRI neural correlates of emotional brain processes in recreational cannabis users after 72 hours of abstinence

    Activation patterns in brain regions known to be involved in emotional processing and to be altered by cannabis use (e.g. striatum, prefrontal cortex, insula, ACC)

    Time frame: one time point = fMRI assessment after 72 hours of abstinence

Secondary outcomes

  1. Ratings of subjective experience (affect, craving)

    Time frame: one time point = during fMRI assessment after 72 hours of abstinence
