CANNABIS, CBD & COVID-19 What science says about CBD as an anti-viral agent.

With the worldwide death toll from the coronavirus rising exponentially, The Lancet drew attention to “accumulating evidence” that indicates “patients with severe COVID-19 might have a cytokine storm syndrome.”

Characterized by intense immune overreaction in the lungs, this little understood syndrome can sicken and kill infected individuals. Respiratory distress is the leading cause of mortality in COVID-19 cases. The critically ill who survive intensive care may suffer long term lung damage, resulting in functional impairment and reduced quality of life.

Science Daily reports that a hyper-inflammatory cytokine storm, involving a surge of immune cells gone haywire, was likely the primary cause of death in several viral outbreaks, including the 1918-20 “Spanish flu” pandemic (which killed more than 50 million people) and, more recently, the H1N1 swine flu and the so-called bird flu.

In cases of acute, viral-induced pulmonary distress, cytokine-storm-targeted therapy would seem to make sense. But treatment with corticosteroids is not a great option because it can exacerbate COVID-19-associated lung injury. “However,” as The Lancet emphasizes, “in hyperinflammation, immunosuppression is likely to be beneficial.”

COULD CANNABIS CALM A CYTOKINE STORM?

Several laboratory studies indicate that cannabinoid compounds – in particular, cannabidiol (CBD) and tetrahydrocannabinol (THC) – are immunosuppressant. This would explain why medical cannabis is beneficial for people with autoimmune diseases and chronic inflammation.

Which begs the question: Could cannabis calm a cytokine storm?

The short answer is we don’t know. There’s a lot that we still don’t understand about cannabis and the immune system.

For many years, scientific inquiry in the United States has been handcuffed by cannabis prohibition, and the federal government continues to thwart research that could shed light on the therapeutic use of cannabis and whole plant CBD-rich oil extracts. The federal stranglehold on cannabis research is the main reason why we know so little about CBD’s clinical potential as an antiviral remedy.

Cannabis prohibition is exacerbating the current crisis in other ways, as well, as we discuss later in this article. For now, let’s turn our attention back to cytokines and cannabinoids.
