Brief summary

This study aims to collect data on the efficacy of clinically prescribed cannabis products from a large-scale cohort to examine the relationships between cannabis treatment and concomitant medication use, pain, symptoms, quality of life, mood and sleep measures in a patient population that includes, but is not limited to, cancer patients. Who is it for? You may be eligible to join this study if you have been prescribed medicinal cannabis through the Special Access Scheme B via Cannvalate and their medical practitioner for any condition including, but not limited to, cancer. If you are under 18 years of age your parents must also consent to your participation in the project. Study details All eligible participants will be emailed a link to an online survey. An automated email will be sent at set intervals (2 weeks, 1 month, 3 months, 6 months, 12 months) from the date of first completion asking patients to complete the survey again. In addition, participants will be asked whether they consent to the investigators accessing their medical records in order to store data in a research database for this and future projects. Participants may choose to participate in one component of the study without the other (e.g. complete survey but not consent to medical records access or vice versa). The survey will take approximately 45 minutes to complete and will be a compilation of the following questions and questionnaires: Demographics, Medical Condition that cannabis is prescribed, dosage, duration and administration of cannabis treatment, general health, pain, symptoms, quality of life, mood and sleep measures. It is hoped that this research will contribute to the knowledge of the safety and efficacy of medicinal cannabis products for different medical conditions.
