Humans have had a long love affair with body and mind modification, but in the present day simple modification is not enough - we now strive for permanent or semi-permanent "enhancement." The use of anabolic steroids by athletes, for example, has brought down world records but also brought incredible shame on the leagues that condoned such abuse.
Now, university students and professors are turning to so-called "cognitive enhancers," also known as "nootropics" or "smart drugs" to improve memory, learning, and overall alertness.
What are smart drugs, and how big is the problem? You might be surprised to find out.
