Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to define common strains of cannabis that adult chronic cancer and non-cancer pain syndrome patients are using as a replacement for opioids (narcotics). Identified strains, if any, will then be tested via randomized controlled trials to support an application for a Health Canada Drug Identification Number.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The search for safer alternatives to opioids for treating chronic cancer and non-cancer pain syndromes currently is an important initiative. Cannabis Research Associates (CRA) has been commissioned by Northern Green Canada Inc. to conduct a multi-phase study that will first define common strains of cannabis that patients use as a replacement for opioids, then conduct a randomized controlled trial to support an application to Health Canada for a Drug Identification Number. This protocol summarizes the methods for phase I.

In total, the Investigators plan to recruit 1,200 adult patients (\> 25 years) currently using cannabis to treat chronic cancer and non-cancer pain syndromes conditions. Patients will be recruited from six pain clinics throughout Ontario. Pain clinics have not yet been identified. The study Investigators will invite licensed physicians from various private pain clinics to collaborate on this study.

This is an observational cohort study involving a mixed methods approach. Patients interested in participating will have the option to have an online survey link emailed to them so they can complete the survey at a convenient time. Or, patients can choose to complete the online survey in person with the assistance of a Research Assistant. Research Assistants will have hard copy surveys to serve as a back-up solution should they be faced with Internet connectivity and/or online survey hosting issues. No personal identifying information will be collected. Hard copy data will be stored in locked cabinets and shipped via courier to Cannabis Research Associates in batches.

All aspects of this study will be executed under the supervision of the study Investigators. Scientific independence from the sponsoring body will be maintained, and no censorship of data management, analysis, or presentation/publication will be permitted.

This study will be executed under the approval and ongoing supervision of the Research Ethics Board, as required.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Adult patients aged \> 25 years-CPSO Policy states that physicians cannot prescribe medical cannabis to persons under the age of 25 unless all other conventional therapies have failed. Furthermore, there is evidence to support that cannabis use in younger persons can have lasting effects since the brain is still developing (Wier K, 2015).
2. English-speaking, or with the assistance of a family member/friend that can interpret English for the patient.
3. Qualifying medical diagnosis for appropriate use of medical cannabis by a licensed physician.
4. Current medical cannabis use to treat chronic cancer and non-cancer pain syndromes.
5. Current or past use of prescription opioids to treat chronic cancer and non-cancer pain syndromes.
