Sorry, but those over the counter inhalers are dangerous to many who use them. They could never get FDA approval now, because of the heart rate increases, and the “rebound” effect, among other things. I’ve treated people in the ER who nearly died using those, and who were quickly improved by the prescription inhalers.
The most common cause of asthma deathsis often underdosing on meds. if some 0bamanite loser wants to get high and achieve room temperature, why should others suffer?
