I just recently discovered about [benzedrine](https://www.wikiwand.com/en/History_of_Benzedrine), the first pharmaceutical to comprise amphetamine that was utilized as a decongestant and cure for asthma.
I am essentially allergic to the atmosphere in any way times so that my nose shuts up along with my lungs become swollen unless I shoot fluticasone regularly.
After studying that land of amph I thought if a part of this clear-headedness I encounter from it’s partially because I’m really getting sufficient oxygen to my mind.
Anyone here with asthma or allergies breathe while taking amphetamine analogues? Or is its own bronchodilation effect entirely overblown?
