Preliminary Study Suggests Cannabis Extracts May Help Prevent COVID-19

Many countries are carrying out a number of researches to find out potential cures for the novel coronavirus. Among the many studies, one preliminary research from Canada suggests that marijuana could be used to prevent coronavirus infections.

Researchers at the University of Lethbridge in Calgary are studying more than 400 strains of cannabis and have found that at least a dozen may offer potential as part of treatments to prevent coronavirus from infecting a host cell, claims reports.

The researchers have reportedly found that in some instances the effective strains have managed to reduce virus receptors, which, in turn, reduces the chances of an individual catching coronavirus.

"A number of them have reduced the number of these receptors by 73 per cent, the chance of it getting in is much lower. If they can reduce the number of receptors, there's much less chance of getting infected," Dr Igor Kovalchuk told the Calgary Herald.

Mr Kovalchuk however said that much more research would be necessary before they understand precisely whether CBD (Cannabidiol), THC or some combination of ingredients is causing the reduction in receptors.

Researchers would likely focus on understanding how high-CBD strains work, as CBD is known to have anti-inflammatory properties. It can be taken frequently and in high-concentration without the risk of getting the patient high or impairing them.

The preliminary study, has not been peer-reviewed yet. But it focuses on preventing coronavirus from finding a host while in the lungs, intestines and mouth.

If further research proves fruitful, Mr Kovalchuk said medicinal mouth washes, gel caps, gargles, or inhalants could potentially be used to help reduce their risk of infection.

"The extracts of our most successful and novel high CBD C sativa lines, pending further investigation, may become a useful and safe addition to the treatment of Covid-19 as an adjunct therapy, Given the current dire and rapidly evolving epidemiological situation, every possible therapeutic opportunity and avenue must be considered,¡± he said.

Apart from the Canadian study, some Israeli researchers too are carrying out clinical trials meant to test whether CBD can be used as a way to repair cells that have been damaged by COVID-19.

Even as various studies and researches progress, the promising Oxford vaccine has reportedly failed to prevent coronavirus spread in monkeys.
The world continues to search for a coronavirus vaccine.
