I don't mean to sound pedantic (though I certainly will), but Focalin, Ritalin, etc are formulations of methylphenidate which is absolutely not an amphetamine. It's a DARI, not a VMAT2 inhibitor. They work in very different ways and are not chemically related.
I only bring this up because if you're trying to educate folks on compounds in this sphere, being accurate is a nice thing to do.
I wish this project all the best. It's absolutely silly that the name of a commonly prescribed compound should be so maligned. What if I named an app "Metformin"? Would that be at risk of uh, encouraging type 2 diabetes?
