“Introduction: Chronic non-cancer pain (CNCP) is one of the most prevalent indications for medical cannabis (MC) treatment globally. In this study, we investigated CNCP parameters in patients during prolonged MC treatment, and assessed the interrelation between CNCP parameters and the chemical composition of MC chemovar used.
Methods: A cross-sectional questionnaire-based study was performed in one-month intervals for the duration of six months. Subjects were adult patients licensed for MC treatment who also reported a diagnosis of CNCP by a physician. Data included self-reported questionnaires. MC treatment features included administration route, cultivator, cultivar name and monthly dose. Comparison statistics were used to evaluate differences between the abovementioned parameters and the monthly MC chemovar doses at each time point.
Results: 429, 150, 98, 71, 77 and 82 patients reported fully on their MC treatment regimens at six one-month intervals, respectively. Although pain intensities did not change during the study period, analgesic medication consumption rates decreased from 46 to 28% (p < 0.005) and good Quality of Life (QoL) rates increased from 49 to 62% (p < 0.05). These changes overlapped with increase in rates of (-)-Δ9–trans-tetrahydrocannabinol (THC) and α-pinene high dose consumption.
Conclusion: Even though we observed that pain intensities did not improve during the study, QoL did improve and the rate of analgesic medication consumption decreased alongside with increasing rates of high dose THC and α-pinene consumption. Understanding MC treatment composition may shed light on its long-term effects.”
“In this study, although pain intensities did not change under long-term MC treatment, analgesic medication consumption rates decreased and ‘better’ QoL rates increased. These changes coincided with the increased rates of patients’ consumption of high dose THC and α pinene. These results may shed light on the long-term beneficial effects of MC on CNCP.”

“Cannabis use for pain relief is commonly reported, yet laboratory studies and clinical trials suggest that cannabinoids are weak analgesics, and it is unclear whether perceived reductions in pain from before to after cannabis use relate to factors such as dose, method of administration, phytocannabinoid content, or the age or gender of the user. We determined whether inhalation of cannabis decreased self-reported pain ratings as well as whether user gender, age, time, method of administration, tetrahydrocannabinol (THC)/cannabidiol (CBD) content, or dose of cannabis contribute to changes in these ratings. We also examined whether tolerance may develop to the analgesic effects of cannabis over time.
“Objective: The opioid epidemic continues to claim thousands of lives every year without an effective strategy useful in mitigating mortality. The use of medical cannabis has been proposed as a potential strategy to decrease opioid usage. The objective of this study was to determine how the use of medical cannabis affects prescribed opioid usage in chronic pain patients.
“Background: The ongoing opioid overdose crisis is driven largely by exposure to illicitly-manufactured fentanyl. Preliminary observational and experimental research suggests that cannabis could potentially play a role in reducing use of prescription opioids among individuals with chronic pain. However, there is limited data on the effects of cannabis on illicit opioid consumption, particularly fentanyl, especially among individuals on opioid agonist therapy (OAT). We sought to assess the longitudinal association between cannabis use and exposure to fentanyl among people on OAT.
“Objectives: This article presents findings from a large prospective examination of Canadian medical cannabis patients, with a focus on the impacts of cannabis on prescription opioid use and quality of life over a 6-month period.
“Chronic pelvic pain (CPP) affects up to 15% of women in the United States. The endocannabinoid system is a potential pharmacological target for pelvic pain as cannabinoid receptors are highly expressed in the uterus and other nonreproductive tissues.
“Opioid misuse and overuse has contributed to a widespread overdose crisis and many patients and physicians are considering medical cannabis to support opioid tapering and chronic pain control. Using a five-step modified Delphi process, we aimed to develop consensus-based recommendations on: 1) when and how to safely initiate and titrate cannabinoids in the presence of opioids, 2) when and how to safely taper opioids in the presence of cannabinoids, and 3) how to monitor patients and evaluate outcomes when treating with opioids and cannabinoids.
“Chronic pelvic pain affects women across all demographics. Its management is complex and requires a multimodal approach.
“Although studied in a few randomized controlled trials (RCTs), the efficacy of medical cannabis (MC) for chronic pain remains controversial. Using an alternative approach, this multicenter, questionnaire-based prospective cohort was aimed to assess the long-term effects of MC on chronic pain of various etiologies and to identify predictors for MC treatment success.
