Some asthma inhalers emit greenhouse gases. But can patients afford to switch? : Shots - Health News

During an asthma check-up, Joel Rubinstein learned about the environmental impact of traditional metered-dose inhalers, which release potent greenhouse gases with each use. His doctor, Dr. Miguel Divo, introduced him to an alternative: dry powder inhalers that don't emit these gases. However, the cost of switching can be prohibitive for some patients, as dry powder inhalers are often more expensive and not suitable for all individuals.

In the U.S., metered-dose inhalers contribute significantly to climate change, comparable to the emissions from half a million cars annually. This creates a vicious cycle, worsening air quality and exacerbating respiratory conditions, thereby increasing inhaler use. Efforts are underway to develop less harmful inhalers, but changes in the industry are voluntary and may lead to higher costs for patients, mirroring past price increases when manufacturers phased out other harmful chemicals.
