Polish Physicians' Perspectives on Medical Cannabis Policy and Educational Needs: Results of An Online Survey

The Use of Compounds Derived from Cannabis sativa in the Treatment of Epilepsy, Painful Conditions, and Neuropsychiatric and Neurodegenerative Disorders

Neurological disorders present a wide range of symptoms and challenges in diagnosis and treatment. Cannabis sativa, with its diverse chemical composition, offers potential therapeutic benefits due to its anticonvulsive, analgesic, anti-inflammatory, and neuroprotective properties. Beyond cannabinoids, cannabis contains terpenes and polyphenols, which synergistically enhance its pharmacological effects. Various administration routes, including vaporization, oral ingestion, sublingual, and rectal, provide flexibility in treatment delivery. This review shows the therapeutic efficacy of cannabis in managing neurological disorders such as epilepsy, neurodegenerative diseases, neurodevelopmental disorders, psychiatric disorders, and painful pathologies. Drawing from surveys, patient studies, and clinical trials, it highlights the potential of cannabis in alleviating symptoms, slowing disease progression, and improving overall quality of life for patients. Understanding the diverse therapeutic mechanisms of cannabis can open up possibilities for using this plant for individual patient needs.

International perspective on physician knowledge, attitude and practices related to medical cannabis

Background

The trends of recreational use of cannabis and use of cannabis for medical indications (i.e. "medical cannabis") have grown in recent years. Despite that, there is still limited scientific evidence to guide clinical decision-making and the strength of evidence for the medical use of cannabis is currently considered to be low. In contrast, there's growing evidence for negative health outcomes related to use of cannabis. In this rapidly shifting landscape, the role of physician's attitudes regarding the therapeutic value of cannabis has become essential. This study aimed to characterize knowledge/experience, attitudes, and potential predictors of clinical practice regarding medical cannabis.

Methods

We conducted a cross-sectional survey of physicians from 17 countries between 2016-2018. The survey comprised of 28 questions designed to explore physician knowledge, attitude, and practices regarding the use of medical cannabis. Descriptive statistics were used to examine willingness to recommend medical cannabis for medical and psychiatric indications, followed by regression analysis to identify predictors of physician willingness to recommend medical cannabis.

Results

A total of 323 physicians responded to the survey. Mean age was 35.4± 9.5 years, with 10.04 ±8.6 years of clinical experience. 53 percent of physicians were women. Clinical experience with medical cannabis was overall limited (51.4% noted never having recommended medical cannabis; 33% noted inadequate knowledge regarding medical cannabis). Overall willingness to recommend medical cannabis was highest for chemotherapy-induced nausea, refractory chronic neuropathic pain, and spasticity in amyotropic lateral sclerosis (ALS).

Conclusion

This international study examining knowledge, attitudes and practices related to medical cannabis among physicians revealed that there are significant gaps in domain-specific knowledge related to medical cannabis. There is wide variability in willingness to recommend medical cannabis that is not consistent with the current strength of evidence. This study thus highlights the need for greater education related to domain-specific knowledge about medical cannabis.

Knowledge, experiences, and attitudes of Australian General Practitioners towards medicinal cannabis: a 2021-2022 survey

BACKGROUND

Medicinal cannabis (MC) products have been available on prescription in Australia for around six years. General practitioners (GPs) are at the forefront of MC prescribing and recent years have seen substantial increases in prescription numbers. This study examined the current knowledge, experiences, and attitudes of Australian GPs around MC. We also compared our findings to those of an earlier 2017 investigation.

METHOD

We conducted a cross-sectional study using a 42-item on-line questionnaire adapted from our earlier 2017 survey. The current survey was completed by GPs attending an on-line, multi-topic educational seminar. Australian GPs (n = 505) completed the survey between November 2021 and February 2022. Data were synthesised using descriptive statistics. MC 'prescribers' and 'non-prescribers' responses were compared using Pearson's χ2 tests.

RESULTS

While most GPs (85.3%) had received patient enquiries about MC during the last three months, only half (52.3%) felt comfortable discussing MC with patients. Around one fifth (21.8%) had prescribed a MC product. GPs strongly supported MC prescribing for palliative care, cancer pain, chemotherapy-induced nausea and vomiting, and epilepsy, more so than in our 2017 survey. Prescribing for mental health conditions (e.g., depression, anxiety) and insomnia received less support. Opioids, benzodiazepines, and chemotherapy drugs were rated as more hazardous than MC. GPs correctly endorsed concerns around Δ9-tetrahydrocannabinol-related driving impairment and drug-seeking behaviour. However, additional concerns endorsed around cannabidiol causing addiction and driving impairment do not agree with current evidence. Consistent with this, many GPs (66.9%) felt they had inadequate knowledge of MC.

CONCLUSION

Acceptance of MC as a treatment option has increased among Australian GPs since 2017. However, there is a clear need for improved training and education of GPs around cannabis-based medicines to provide increased numbers of skilled prescribers in the community.

To Treat or Not to Treat? Polish Physicians' Opinions about the Clinical Aspects of Cannabinoids-An Online Survey

Introduction: Medical cannabis’ importance in Poland increased dramatically following its legalization as the 12th country in Europe in 2017. However, no studies have been published to give insight into Polish physicians’ opinions about medical cannabis. Objectives: To investigate physician’s opinions about cannabinoids’ utility in clinical practice, concerns regarding their safety profile, and their clinical experience with cannabinoids. Methods: The survey using a self-developed tool was conducted online; participants were physicians with or without specialist training. Participation was voluntary. Physicians were recruited through personal networks, palliative care courses, and Medical Chambers. Results: From June to October 2020, we recruited 173 physicians from 15/16 voivodeships. The largest age group (43.9%; n = 76) was 30–39 year-olds. A similar proportion declared they never used cannabis and did not receive any training regarding cannabinoids (60% for both). Only 15 (8%) ever prescribed medical cannabis, although about 50% declared knowing suitable patients for such therapy, and 53.8% had at least one patient proactively asking for such treatment in the last 6 mo. The most common indication chosen was pain: chronic cancer-related (n = 128), chronic non-cancer (n = 77), and neuropathic (n = 60). Other commonly chosen conditions were alleviation of cancer treatment side-effects (n = 56) and cachexia (n = 57). The overall safety profile of THC was assessed as similar to most commonly used medications, including opioids; NSAIDs and benzodiazepines were, however, perceived as safer. Conclusions: Polish physicians favored the legalization of medical cannabis. However, it is of concern that a limited number have any experience with prescribing cannabis. The creation of clear guidelines to advise physicians in their routine practice and education about pain management and the risks related to the consumption of recreational cannabis for medical conditions are needed.
