London, United Kingdom: The sustained vaporization of THC-dominant cannabis flowers improves health-related quality of life measurements in patients suffering from chronic pain and anxiety-related disorders, according to observational data published in the journal Biomedicines.
A team of British and Spanish investigators assessed cannabis’ efficacy in a cohort of 451 British patients authorized to consume cannabis flowers for treatment-resistant pain and/or anxiety. Patients in the study were all enrolled with Project Twenty21, “the first U.K. multi-center registry seeking to develop a body of real-world evidence to inform on the effectiveness and safety of medical cannabis.” All of the study’s participants had failed to respond to at least two prescription treatment options prior to obtaining an authorization for medical cannabis. All participants vaporized cannabis flowers for a period of at least three months.
Researchers reported that cannabis inhalation was associated with sustained (6+ months) improvements in both patient populations and that side effects were “minimal.” Investigators reported more significant improvements among those diagnosed with treatment-resistant anxiety.
“Our results indicate that controlled inhalation of pharmaceutical grade, THC-predominant cannabis flos [flowers] is associated with a significant improvement in patient-reported pain scores, mood, anxiety, sleep disturbances and overall HRQoL [health-related quality of life] in a treatment-resistant clinical population,” authors concluded.
