Many Scientists using Performance Enhancing Drugs

I honestly don't know what to make of this: Many Scientists using Performance Enhancing Drugs.

"A new poll published in Nature shows unprecedented levels of cognitive performance-enhancing drug abuse by top academic scientists. The poll, conducted among subscribers to Nature, surveyed 1,400 scientists from 60 nations (70% from the US).  20% reported using performance-enhancing drugs. Among the drug-using population, 62% used Ritalin, 44% used Provigil, and 15% used beta-blockers like Inderal.  Frequency of use was evenly divided among those who used drugs daily, weekly, monthly, and once a year.

Well why not – whatever works…  perhaps one of these performance-enhanced scientists will find a cure for cancer.

However for me I’m sticking with the tried and true performance enhancers like caffeine and chocolate!
