When a patient is referred to our outpatient clinic with a request for medical cannabis, several questions come to mind:. Most of our patients have either tried medical cannabis or read about its role in symptom control. Those who have tried it recreationally or for medical purposes can accurately reflect on the benefits or the adverse effects experienced, which makes the discussion somewhat easier.
Those who have little knowledge and less experience require a complete discussion with respect to the benefits, the possible adverse effects, the process of application and authorization, and the cost which is borne by the patient, because it is not covered by provincial or private medical insurance.
Table iii lists our contraindications to authorization, which are similar to those published by Health Canada 70 , the College of Family Physicians of Canada 71 , and the Canadian Medical Protective Association It should be noted that no special license or additional certification is necessary to authorize the use of medical cannabis, but a working knowledge of cannabis as already presented is helpful for oncology professionals who are considering a patient request.
Once the decision is made to support authorization, the choice of which licensed producer and product to use can be somewhat difficult for some patients.
The more than 30 licensed producers list more than products for sale, which can be a problem for those who do not have experience with cannabis or patients who might be elderly or excessively fatigued.
We do not advise that patients smoke the dried product; rather, they should vaporize, which is likely safer in the long run We also advise neophytes to choose a product that has a balanced thc: Cannabinoid proportions can be guided by available efficacy data summarized in Table iv. Once patients have started to use the product and document the effects, the thc: Conditions potentially responding to cannabinoid therapies 74 — Titration of dose should follow the effect on the symptom in question for example, pain reduction, nausea control.
Follow-up with patients is essential to determine benefits and any adverse effects, questions about use or strain selection, and outcomes. Certainly, if the adverse effects are not tolerable, then an alternative therapy should be considered. If the patient is not getting the desired symptom control, then some dose modification might be necessary. Discontinuation of cannabis should be considered if an adequate trial does not result in the desired outcome as determined by the treating team or the patient.
Inter-professional collaboration is the new paradigm under which modern health care operates Research has demonstrated that inter-professional collaboration is enabled and promoted by inter-professional education, especially at the undergraduate level 79 , Although physicians ultimately authorize and prescribe cannabinoid therapies, valuable insights and inputs about achieving optimal patient outcomes can be derived from other members of the health care team, including nurses, social workers, rehabilitation therapists, and pharmacists.
Furthermore, pharmacies are designed to ensure proper storage and security of medical products. Pharmacists are also well positioned to comprehensively counsel patients and caregivers on the optimal methods of opioid and by extension, cannabis storage and disposal so as to limit diversion and unintentional exposure Moreover, given the emergence of cannabinoids as a novel therapeutic class, cannabinoid education for medical professionals as well as for patients and caregivers should be conducted per the principles of inter-professional education Industrialized countries are experiencing exponential increases in the utilization of opioids 84 , Major public health issues are emerging as a result, not the least of which relate to drug diversion, opioid addiction, and death from opioid overdose 84 , Currently, opioids remain the mainstay of cancer pain management, and increased cancer survival translates into patients using opioids for longer periods of time High-dose and long-term opioid therapy in cancer patients is becoming a concern, given observed risks such as poly-endocrinopathy, osteoporosis, and immunosup-pression Preclinical studies have demonstrated that certain opioids—such as codeine, morphine, methadone, and remifentanil—are associated with increased morbidity and mortality attributable to worsening of cancer and infections Opioid-induced hyperalgesia syndrome is also being reported with increased incidence, especially in patients with advanced cancer and escalating pain Thus, it behooves physicians to explore options that will allow for improved overall pain relief while curbing the overuse of opioids.
Observational studies in advanced cancer cohorts have demonstrated that cannabinoid therapies are associated with opioid-sparing and improved analgesia Published data on the addiction potential for recreational cannabis reflects a risk of 9.
Finally, a British study showed that the overall harm score for user and society for recreational cannabis score: Because medical cannabis generally tends to have a higher ratio of cbd to thc , it would be expected to be associated with a lower predilection to diversion, less addiction potential, and lower overall harm scores than those for recreational cannabis The integration and broader utilization of cannabinoid therapies within the domain of oncology including palliation carries the potential not only for improved health care outcomes for patients but also for economic savings and greater safety for society 90 , Patient reports of improvement in quality of life, especially for those undergoing intensive treatment regimens, could be key to patients continuing with lifesaving or life-prolonging therapies.
Cannabinoids might be able to help patients throughout their disease trajectory, but evidence about the ideal timing for cannabinoid initiation is lacking. More research will guide oncology and palliative care teams in their pursuit of excellence in cancer and symptomatic care.

My dad was recently diagnosed with stage 4 pancreatic. We are trying hard to be very positive during this time. I love hearing more positive feedback. What did u do that u have managed to still be here with us? Did u do chemo?
What is your opinion on cbd oil for the pain as he is not taking any pain meds and is it possible to stop it growing further and maybe reduce the size of the tumour? Chemo was my only option as the cancer had grown around my aorta and spread to distant parts.
I was lucky that my cancer isn't painful - though that's also why it wasn't suspected until stage 4 which was ufortunate. I've not tried alternative pain killers and to be honest can't imagine trying cbd unless conventional drugs had been tried and found not to work. I hope your partnet changes his mind about chemo. There's a lot of disinformation out there and myths based on how bad chemo was in the s and 70s, along with deliberate misinterpretations of scientific evidence to help sell cannabis oil and other alternative rather than complementary treatments.
The side effects can be managed these days to a high degree and there are a hundred times more types and combinations of chemo than there ware even 20 years ago. I was given a combination of three types of chemo because this is more effective and longer lasting than the traditional one chemo regime.
