Cannabis as Medicine? Overview

It is utterly mind-blowing that people have no idea that Cannabis has been part of the medical prescription landscape for over 20 years. That’s right T. G. A (Therapeutic Goods Administration) trialled and approved cannabis based medicines have been available as an option to alleviate, if only in small ways, some of the symptoms of a couple of diseases or help with recovery from treatment. However, the claims of this plant being a ‘miracle cure’ for just about everything, have existed for of 100 years… yet in no credible and advanced research has any of the properties of the Cannabis plant ‘cured’ anything, ever!

There is no argument that some components of this incredibly complex plant can have some therapeutic benefit, be it ever so small, but deriving such from the plant with out co-opting some of the more detrimental components has proven incredibly difficult. On top of that, the evidence emerging from latest science, sees that some of these therapies, do more harm than good, with the temporary alleviating of a symptom on one hand, and incurring along term genetic harm on the other!

Again if facts and evidence matter to your best-practice health care, then this is the space for you. Make informed decisions based on science, and not quackery!

Oral cannabidiol (CBD) as add-on to paracetamol for painful chronic osteoarthritis of the knee: a randomized, double-blind, placebo-controlled clinical trial.

Background: Painful knee osteoarthritis (KOA) is common, pharmacological treatment, however, is often hampered by limited tolerability. Cannabidiol, which preclinically showed anti-inflammatory, analgesic activity, could supplement established analgesics, but robust clinical trials are lacking. The aim of our study was to investigate the effects of oral high-dose CBD administered over 8 weeks on pain, function and patient global assessment as an add-on to continued paracetamol in chronic symptomatic KOA.

Methods: Prospective, randomized, placebo-controlled, double-blind, parallel-group study. Single center, Outpatient Clinic, Department of Special Anaesthesia and Pain Therapy at Medical University of Vienna, Austria. Eligibility criteria included: age: 18–98 years; painful KOA; score ≥5 on the pain subscale of the Western Ontario and McMasters Universities Osteoarthritis (WOMAC) Index; KOA confirmed by imaging. Participants were on continued dosage of paracetamol 3 g/d and randomly assigned by web-based software 1:1 to oral cannabidiol 600 mg/d (n = 43) or placebo (n = 43). Study period: 8 weeks. Primary outcome: Change in WOMAC pain subscale scores (0 = no pain, 10 = worst possible pain) from baseline to week 8 of treatment. Trial Registration: ClinicalTrials.gov Identifier: NCT04607603. Trial is completed.

Interpretation: In KOA patients, oral high-dose add-on cannabidiol had no additional analgesic effect compared to adding placebo to continued paracetamol. Our results do not support the use of cannabidiol as an analgesic supplement in KOA
