Provigil: a new drug to make us smarter

I've been reading The Power of Now and A New Earth by Eckhart Tolle, in which he proposes that that the mind is a tool, which we need to learn to use and then put aside. Now Provigil and other smart drugs offer a way to enhance the mind's effectiveness.

With the smart drug provigil, instead of getting high, you get focused. Some call it steroids for the brain, still others have dubbed provigil viagra for the mind. Wouldn't it be nice if progivil could make us smart enough to solve some of the world's pressing problems?

But thinking deeper... what will this kind of brain enhancement opportunity lead to? Will there be a new wave of academic doping? Peer pressure to take it at work? The New York Times offers an interesting review of the ethics at play. Johann Hari blogs eloquently about his personal experience.
