I would use that for slightly less than valid medical reasons but not for junkie druggy reasons. It does to me what I imagine coffee should do but doesn't. And at a school like mine being awake, alert, and focused means the difference between making six figures in 5-6 years when I graduate and being homeless.
I want the people to be happy,
a world without violence and evil thoughts,
and who will help the poor and needy,
and do good deeds, because it is for us to do good on earth God All Mighty gave us life!
People wish for things that won't ever happen all that time. Like the cure for my wife's and son's disability. That may never happen in my lifetime. No reason to feel bad, they just give you something to hope for everyday of your life.
