Cognitivity-enhancing drugs seeing more ethical debate

Have you ever taken or known someone who has taken a "brain boosting" drug? These products are designed to raise performance for exams or work (or both, plus more), but according to some doctors this past week, their use does indeed raise long-term ethical and safety concerns.

Ethical concerns surface when drugs are given to people who are not ill, but who are willing to pay for the product regardless. Is this something the medical establishment should do?

It it may become worse, as it's estimated that the ability of prescription drugs and medical procedures to improve intellectual performance will probably see huge increases in the next few decades.
