Over 10 yrs ago my asthma inhaler went generic and became cheap. But the govt said the propellant was bad for the environment, mandated a new type, and I was back to buying branded for $$$$. Recently that new type went generic as well. Cheap again! Yay! Except now the govt says this propellant is *also* unsafe, and will be banning it, forcing everyone to buy a (patented of course) newer more expensive type yet again. Funny how the timing works that drugs become “unsafe/environmentally bad” juuuust as the pharmaceutical patents run out. Very curious, that.
