Wow - thanks for posting. One interesting thing that stood out for me was the use of a justification that parallels the MLB steroid excuses:
"Asked if the improper use of stimulants was cheating, students were split. Some considered that the extra studying hours and the heightened focus during exams amounted to an unfair advantage. Many countered that the drugs “don’t give you the answers” and defended their use as a personal choice for test preparation, akin to tutoring."
Ya sure . . . just like androstenedione didn't help McGwire to hit a baseball - it just made it go a heck of a lot farther when he did hit it. Just personal preparation.
