Professor Henry T. "Hank" Greely is quoted in a story about the increasing use of productivity-enhancing drugs in the workplace:

Hank Greely, a law professor and director of Stanford University's Center for Biomedical Ethics, said he also knows some academics and doctors who have tried Provigil and who apparently didn't have sleep disorders. He added that some of them may have had prescriptions for it, however, which muddies the issue of how appropriate it was for them to use the drug.

"If, in fact, drugs are able to make people smarter and more effective in their work, that could produce net benefits to society,'' said Stanford's Greely. But he expressed concern that the poor might not have equal access to the drugs and that bosses might coerce employees to take them to increase the work they do.
