Inhalers are the frontline treatment for asthma and COPD, but they come with a steep environmental cost, according to a new UCLA Health study—the largest to date quantifying inhaler-related emissions in the United States.
Researchers found that inhalers have generated over 2 million metric tons of carbon emissions annually over the past decade, equivalent to the emissions of roughly 530,000 gas-powered cars on the road each year.
If you add 530,000 cars to the worlds total of ~1.5 billion cars that’s a drop in the bucket.

Edit: what I’m trying to say let’s focus on replacing them with EVs and improve public transportation. And let the asthmatics have their inhalers.
On top of that, we have that automobiles are less than a quarter of total emissions.
