The goal of this interventional study is to learn about the effect of Medicinal Cannabis (Bedrocan®) on Fibromyalgia patients with pain resistant to conventional therapy. The main question the trial aims to answer are: * Is Bedrocan® effective for treating fibromyalgia-related pain in patients resistant to conventional therapy? * Can a low dosage of medical cannabis taken as a decoction reduce fibromyalgic pain? All patients were trained on how to make the decoction: therapy was started with 100 mg/day (1 folder) and increased to 200 mg/day (2 folders) in non-responders.
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.

Pain intensity
Pain intensity evaluated with the Numerical Rating Scale (NRS). NRS involves asking individuals to rate their pain on a numerical scale typically ranging from 0 to 10, where 0 represents no pain and 10 represents the worst possible pain.
Time frame: 6 months
Physical state
Physical state was evaluated with the Physical Component Summary of the Short-form health survey SF-12 questionnaire (PCS-12). The PCS-12 provides a summary score that reflects the individual's overall physical health status; it can range from 10.5 to 69.7, with higher scores indicating better physical functioning and well-being.
Time frame: 6 months
Mental state
Mental state was evaluated with the Mental Component Summary of the SF-12 questionnaire (MCS-12). MCS-12 provides a summary score, ranging between 7.4 to 72.1, that reflects the individual's overall mental health status. Higher scores on the MCS-12 indicate better mental well-being, while lower scores may indicate higher levels of psychological distress or impairment in social and emotional functioning.
