I actually did this when I was in college. I started as a participant, then started recruiting, and also worked as a monitor. When I left, I was trained as a phlebotomist (someone who draws blood). I did a ton of studies. Most were harmless like Diclofenac, Naproxen Sodium and countless others. The first study I did was for Morphine and the company did several studies in various strengths. I was in the study that did 15mg dose, but they went as high as 30mg and had some issues with the higher doses. Since they were dosing people on empty stomachs the higher dosed participants threw up sometime after being dosed. There were two people in the 30mg morphine study who got black listed from the company when they found out they weren't taking the dosage. I'm surprised the guy in the article still got paid considering its pretty easy to tell if you've taken the drug they give you. The guy who ran the place I was at said when they do blood draws, they can track the drug through your system. It's like a bell curve. Your body absorbs the drug, then gradually gets rid of it. If you don't take the pill, the line is totally flat. I have a ton of stories since I worked for the company almost my entire college career in some aspect or another. Since I worked both sides of the equation, I could probably answer any question people have about doing this. EDIT: The interesting they left out of the article was how this is taxed, and if you have to pay taxes on this kind of work. It's something I ran into with the company I was at.
