“Aims: Patients with chronic health conditions not responding to conventional treatment can access medicinal cannabis (MC) prescriptions from clinicians in Australia. We aimed to assess overall health-related quality of life (HRQL), pain, fatigue, sleep, anxiety, and depression in a large real-world sample of patients accessing prescribed medicinal cannabis. We hypothesized that all patient-reported outcomes (PROs) would improve from baseline to 3-months.

Methods: The QUEST Initiative is a large prospective multicenter study of patients with any chronic health condition newly prescribed medicinal cannabis between November 2020 and December 2021. Eligible patients were identified by 120 clinicians at medical centers across six Australian states. Consenting participants completed the EuroQol Group EQ-5D-5L health status questionnaire; European Organization for Research & Treatment of Cancer Quality of Life questionnaire (QLQ-C30); Patient-Reported Outcomes Measurement Information System (PROMIS) Short Forms in Fatigue and Sleep Disturbance, and the Depression Anxiety Stress Scale (DASS-21) before starting therapy, at 2-weeks titration, then monthly for 3-months.

Results: Of the 2762 consenting participants, 2327 completed baseline and at least one follow-up questionnaire. Ages ranged between 18-97 years (mean 51y; SD = 15.4), 62.8% were female. The most commonly treated conditions were chronic pain (n = 1598/2327; 68.7%), insomnia (n = 534/2327; 22.9%), generalized anxiety (n = 508/2327; 21.5%), and mixed anxiety and depression (n = 259/2327; 11%). Across the whole cohort both EQ-5D-5L utility scores and QLQ-C30 summary scores showed clinically meaningful improvement in HRQL from baseline to mean follow-up with d = 0.54 (95%CI:0.47 to 0.59) and d = 0.64 (95%CI:0.58 to 0.70) respectively; and clinically meaningful improvement in fatigue (d = 0.54; 95%CI:0.48 to 0.59). There was clinically meaningful reduction of pain for those with chronic pain (d = 0.65; 95%CI:0.57 to 0.72); significant improvements for those with moderate to extremely severe anxiety (X2 = 383; df = 4; p<0.001) and depression (X2 = 395; df = 4; p<0.001); and no changes in sleep disturbance.

Conclusions: We observed statistically significant, clinically meaningful improvements in overall HRQL and fatigue over the first 3-months in patients with chronic health conditions accessing prescribed medical cannabis. Anxiety, depression, and pain also improved over time, particularly for those with corresponding health conditions. The study continues to follow-up patients until 12-months to determine whether improvements in PROs are maintained long-term.”

“Short-term findings over 3-months indicate that patients prescribed MC in practice have improved HRQL and reduced fatigue. Patients experiencing anxiety, depression, or chronic pain also improved in those outcomes over 3-months, but no changes in sleep disturbance were observed in patients with sleep disorders.”

“Introduction: Medical cannabis has been used to relieve the symptoms of people with various chronic diseases. Despite of this, it has been stigmatized, even after its legalization in many countries.

Aim: The purpose of this study was to investigate the quality of life of patients receiving medical cannabis.

Material and method: One hundred patients receiving medical cannabis were given (a) a socio-demographic and clinical questionnaire, and (b) the SF-36 Health Survey scale for assessing quality of life.

Results: The majority of our patients who received medical cannabis to treat their neurological disorders (58%) reported decrease in their symptoms (96%), better energy and vitality (68%), ability to perform their professional duties (88%), and an improvement in sleeping and appetite (79% and 71%, respectively) after receiving medical cannabis. Our participants exhibited very few restrictions in activities due to emotional difficulties, a moderate general health status as well as moderate vitality and energy. Participants, who reported a longer period of receiving medical cannabis, reported statistically significant more energy and vitality (p = 0.000), but also better mental (p = 0.000) and general health status (p = 0.001). Furthermore, the majority of patients have disclosed medical cannabis use to their family members (85%) and enjoyed their support (93%), but they haven’t revealed their medication treatment to their social environment (81%).

Conclusions: Appropriate knowledge could significantly help health professionals in the field of planning and implementation of personalized nursing care in order to achieve optimal therapeutic outcomes.”

“Background: To evaluate the impact of medical cannabis laws (MCLs) on health insurance premiums. We study whether cannabis legalization significantly impacts aggregate health insurer premiums in the individual market. Increases in utilization could have spillover effects to patients in the form of higher health insurance premiums.

Methods: We use 2010-2021 state-level U.S. private health insurer financial data from the National Association of Insurance Commissioners. We examined changes to individual market health insurance premiums after the implementation of medical cannabis laws. We employed a robust difference-in-differences estimator that accounted for variation in policy timing to exploit temporal and geographic variation in state-level medical cannabis legalization.

Results: Seven years after the implementation of Medical Cannabis laws, we observe lower health insurer premiums in the individual market. Starting seven years post-MCL implementation, we find a reduction of $-1662.7 (95% confidence interval [CI -2650.1, -605.7]) for states which implemented MCLs compared to the control group, a reduction of -$1541.8 (95% confidence interval [CI 2602.1, -481.4]) in year 8, and a reduction of $-1625.8, (95% confidence interval [CI -2694.2, -557.5]) in year 9. Due to the nature of insurance pooling and community rating, these savings are appreciated by cannabis users and non-users alike in states that have implemented MCLs.

Conclusions: The implementation of MCLs lowers individual-market health insurance premiums. Health insurance spending, including premiums, comprises between 16% and 34% of household budgets in the United States. As healthcare costs continue to rise, our findings suggest that households that obtain their health insurance on the individual (i.e., not employer sponsored) market in states with MCLs appreciate significantly lower premiums.”

“Background: Cannabis use, be it either cannabidiol (CBD) use and/or delta-9-tetrahydrocannabinol (THC) use, shows promise to enhance exercise recovery. The present study aimed to determine if individuals are using CBD and/or THC as a means of recovery from aerobic and/or resistance exercise, as well as additional modalities that might be used to aid in recovery.

Methods: Following consent, 111 participants (Mean ± SD: Age: 31 ± 13 years) completed an anonymous survey. All participants were regularly using cannabis (CBD and/or THC) as well as were currently exercising. Questions pertained to level of cannabis use, methods used for consumption of cannabis, exercise habits, exercise recovery strategies, and demographics.

Results: Eighty-five percent of participants reported participating in aerobic training. In addition, 85% of participants also reported regular participation in resistance exercise. Seventy-two percent of participants participated in both aerobic and resistance exercise. Ninety-three percent of participants felt that CBD use assisted them with recovery from exercise, while 87% of participants felt the same regarding THC use.

Conclusions: Individuals who habitually use cannabis, CBD or THC, and regularly engage in exercise do feel that cannabis assists them with exercise recovery. More data are necessary to understand the role of cannabis in exercise recovery as well as perceived ergogenic benefits of cannabis by individuals who both regularly participate in exercise and habitually use cannabis.”

“CBD or THC use have been suggested to play a role in pain management, inflammation, and sleep, which are hallmarks for recovery from exercise. While data are lacking, it is clear that individuals are using cannabis and believe cannabis to have a positive effect on recovery from exercise. The present study demonstrated that in addition to more traditional recovery methods, cannabis is used as an ergogenic recovery aid by individuals that exercise regularly.”
