Given this, there are no specific dosage guidelines when it comes to using CBD oil for COPD.
Lung function testing is called spirometry. This is a simple breathing test that may be able to tell if you have COPD and define its stage.
2. CBD as an Anti-Inflammatory
Medical researchers have been exploring the potent anti-inflammatory properties of CBD since 2009. Recently, a 2014 trial showed that CBD could improve lung function and reduce inflammation in animal models.
This depends on several factors.
However, if you dislike the taste of natural or mint-flavored CBD oil, or you don’t have time to take measurements and need an easier way to take CBD, you may try Royal CBD capsules. They come as easy-to-ingest softgels; each capsule carries 25 mg of full-spectrum CBD, allowing for convenient dosing and easy use on the go.

Some positive results have come from animal studies. A 2015 study on guinea pigs showed CBD helped open up the bronchial passages. Researchers believe it’s possible it could help people with COPD breathe easier and keep blood oxygen levels from falling, too. And a 2014 study on mice with damaged lungs showed CBD helped lower inflammation and improved lung function.

At the same time, pure hemp seed oil, which comes from a different part of the hemp plant, and other hemp products don’t have CBD or THC. The FDA says they’re safe. But CBD/hemp oil combos exist and blur the lines even more.

But there’s nothing out there yet to say CBD doesn’t help, either, Mannino says.
