Primary outcomes

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

Time frame: one time point = fMRI assessment 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)

Secondary outcomes
