Can CBD Prevent Or Cure COVID19?
Simply, no it cannot! There are a lot of false claims being made online that are saying CBD or Cannabis can prevent or cure this coronavirus. This is false! There are no solid scientific evidences proving that CBD has any preventative or curable effects of COVID19. Mid-march 2020, the International Association for Cannabinoid Medicines (IACM) has posted on LinkedIn regarding these false claims. Yes, cannabis has been found to potentially have antibacterial and antiviral effects. But, as of date, the statement by the IACM Board emphasized that there is no evidence that individual cannabinoids (CBD and THC) can protect against COVID19. Likewise, there is also no evidence showing that there is an increased risk of viral infection, if cannabis is consumed.
Do Not Smoke Weed If Your Sick Or Have Corona Virus
Don’t smoke, if you’re sick – Since, there aren’t any solid data presently available regarding the correlation between cannabis and its impact on the lung health, it’s best if smoking is avoided if you’re sick or show COVID19-associated symptoms. COVID19 is a respiratory infection and has been shown to be infecting the nose, throat, and lungs at various degrees across the population. During this time, it is better, if you can keep your lungs as healthy as possible, if the worst happens.
