Could Cannabis Help People With Lung Diseases?

There is much talk in medical circles about the use of medical marijuana (or cannabis) for a variety of chronic illnesses, but could it also benefit those living with chronic lung disease?

Medical marijuana is currently legal in 23 states in the U.S., as well as Washington, D.C., but its use is a contentious issue with as many people for it as are against it.

How could medical marijuana help those living with chronic lung diseases? According to the Lung Institute, medical marijuana has been found useful in reducing inflammation, improving sleep, easing pain, supporting the immune system, and reducing phlegm. However, one of the big issues when it comes to using cannabis if you have a pulmonary disease, is smoking.

Smoking cannabis is harmful to those with lung diseases as there is generally no filter on the “joint” and people tend to inhale deeper, leaving the smoke in the lungs for much longer than cigarettes or other tobacco products. The American Thoracic Society strongly argues against the smoking of marijuana, citing that it can cause large air sacs (bullae) to form in the lungs which could pop and cause lung collapse, ironically this is more likely to happen to marijuana smokers who are younger rather than older (under 45).

However, there are alternatives to smoking. Many people who don’t already smoke but want to get the benefits of medical marijuana choose to either ingest the product through edible items (such as cookies or brownies) or vapor (where the cannabis is heated at a lower temperature than burning which releases the active ingredients into a steam or vapor which can then be inhaled).

Some people may find that medical marijuana offers temporary relief from some of the symptoms of lung disease, but as it also comes with the side effect of getting high, there is a legal, moral and safety dilemma for many.

    Hi I understand it can be taken as an oil. Cannabis is beneficial for lots of medical conditions and the one that benefits people with COPD has a high TCH content. To counter the effects of a ‘high’ it can be used in suppositories, or can be taken with citoline or peppercorns.
    There should be more research into it and it should be made legal for those with chronic lung diseases. Currently we have to rely on antibiotics which have lots of nasty side effects.

      CBD oil made from Cannabis doesn’t have the THC in it so you don’t get high. My sister has been using it for insomnia. She has exzema and said it is better than its ever been and she notices her fingernails are stronger. I just bought some to try to see if it helps my insomnia. I have Bronchiectasis due to Mycrobacterium Avium. Had lung cancer two years ago
