Opinions on smart drugs - immoral/unfair?

[Sedna]

Short introduction: Smart drugs or nootropics enhance various brain functions like memory, cognition, attention etc.
A couple of popular ones: Piracetam, Noopept, Phenibut(addictive), and many others.

Personally I see nothing wrong with the use of cognition enhancing drugs because none of them really make you THAT overclocked. They arent even slightly close to NZT-48.

I see it as a nice motivating factor in studies and a part of school, though I personally dont take any of them regularly, when I do it is more like a one time thing to keep me concentrated on studying and whatever else.

Whats your thoughts on this?
Some will consider it unfair, or unnatural or weak.

Do they work well for you?
I've never heard of anything like this. From the little I learned just googling them right not, I see nothing wrong with it. It might be interesting to try out one day...
