Brief summary

Project Twenty21 Australia is an observational study which will follow patients prescribed medicinal cannabis who have been diagnosed with either chronic pain, anxiety, post-traumatic stress disorder or multiple sclerosis. They will be followed for up to 6 months. The purpose is to investigate whether medicinal cannabis products are efficacious in alleviating the symptoms associated with these conditions, and if they are safe and tolerable.

Interventions

This observational study will be conducted to observe patients for up to 6 months after receiving cannabis medicines for the treatment of one of four conditions: chronic pain, anxiety, PTSD and MS. The study will be conducted over 2022 and 2023, with recruitment ending at the end of May 2023 and data collection ending at the end of November 2023.

This observational study will be conducted to observe patients for up to 6 months after receiving cannabis medicines for the treatment of one of four conditions: chronic pain, anxiety, PTSD and MS. The study will be conducted over 2022 and 2023, with recruitment ending at the end of May 2023 and data collection ending at the end of November 2023. The study will collect demographic data including gender, age, as well as medical condition, height/weight/BMI, and current medications at baseline- this is collected via an online form emailed to the participant after signing their informed consent form. This information is automatically uploaded to the study database. Participants will complete online questionnaires at baseline, then 3 months and 6 months. Recruitment for the study will end at the end of May 2023 and the study data collection will end at the end of November 2023. The questionnaires will take approximately 15-20 minutes to complete. Participants complete a questionnaire specific to their condition (ie. for chronic pain, MS, anxiety, PTSD)- there are two questionnaires for MS. Participants also complete questionnaires assessing quality of life, sleep, depression/mood, two questionnaires about side effects and behavioural changes, and a questionnaire about impact of treatment. To assess safety, pathology (blood) tests are conducted at baseline, then at 6 months.
