Verdict
CBD (cannabidiol) has been studied for asthma in animals, not yet in people.
Unproven means: it was only tested in animals or cells, or there is too little or mixed data from people. How we rate claims
What this means for you: Results in animals or in cells often do not hold in people. Do not stop or change your medicines because of it. Ask your doctor before you start taking it.
