Philip Morris International cigarettes can cause lung disease. Now the company wants to sell medicine to treat it.

In July, Philip Morris International snapped up the Danish firm Fertin Pharma, which makes medicinal chewing gum. That was followed by U.S. drug company OtiTopic, which is developing an aerosolized drug to treat heart attacks. Philip Morris also recently unveiled plans to pay $1.4 billion for the British drug firm Vectura, a major developer of inhaled treatments for COPD and other respiratory ailments, including a potential covid-19 treatment.
