Study Description

The study took place in the pain therapy unit of San Carlo Hospital (Potenza, Italy) between March 2021 and September 2021. Over this period, 44 subjects visited the pain unit and underwent specialist evaluation. Fibromyalgia syndrome was confirmed using the Widespread Pain Index (WPI) and Symptom Severity (SS) scale criteria, resulting in the recruitment of 34 subjects. Two participants discontinued therapy due to side effects, while 2 other patients were excluded for not initiating treatment within the required timeframe. Therefore, the final number of recruited fibromyalgic subjects for the study was 30. Among these subjects, those who provided informed written consent for starting the trial with medical cannabis were prescribed Bedrocan® once a month, with a total of 30 prescriptions per month for a duration of 6 months.

All patients were instructed on how to prepare the decoction; the therapy was started with 100 mg/day (1 chart) and increased to 200 mg/day (2 charts) in non-responsive subjects.

The Numerical Rating Scale (NRS) and SF-12 Short Form health questionnaire were used to evaluate pain intensity and the quality of life at the beginning of the study and 6th-month follow-up.
