Have you tried CBD?
According to theAmerican Lung Association, 16 million Americans reported that they had COPD in 2018.
How CBD can help
Another possible alternative way to manage COPD symptoms?

Research has shown that smoking marijuana opens air passages (viaWebMD).
Of course, smoking anything isn’t good for your lungs long-term.
COPD causes inflammation in your lungs, and another helpful side effect of CBD is that it eases inflammation.

Studies show that CBD acts as an anti-inflammatory for inflamed lungs.
Even so, there have been small trials that suggest positive findings are on the horizon (viaHealthline).
As of now, though, professional opinions are mixed.

However, in the meantime, CBD has plenty of benefits that still may make your life easier.
