There is no direct link between cannabis use and treating colds and the flu. However, there is new evidence suggesting symptoms can be managed if cannabis is used responsibly.
The cannabinoids THC and CBD have been shown to have pain-relieving, sleep-inducing, and anti-inflammatory properties. So cannabis may help reduce body aches, ease inflammation of the airways, and increase relaxation to help you sleep.
As for flu symptoms, cannabis may also have antipyretic or fever-reducing properties, due to its ability to suppress the immune system.
Research suggests CBD has anti-viral properties.
