About this trial

The aim of this trial is to determine the potential effects and mechanisms of cannabinoid-induced pain relief in complex regional pain syndrome (CRPS). Multiple psychophysical approaches will be conducted in conjunction with psychological and inflammatory marker testing to determine if and how cannabinoids produce stabilized improvement in CRPS-related pain and comorbidities.

The trial consisted of a pre-treatment screening period, six-week treatment period and a two-week follow-up.
