Asthma carbon footprint 'as big as eating meat'
Making the swap would have as big an "eco" impact as turning vegetarian or becoming an avid recycler, they say.
It's because some inhalers release greenhouse gases linked to global warming.
There are more than five million people with asthma in the UK.
The research looked at the environmental impact of different inhaler medications prescribed to patients on the NHS in England.
In 2017, about 50 million inhalers were prescribed. Seven out of every 10 of them were metered-dose inhalers - the type that contain greenhouse gases.
The gas - hydrofluoroalkane - is used as a propellant to squirt the medicine out of the inhaler.
Metered-dose inhalers account for nearly 4% of NHS greenhouse gas emissions, according to experts.
