That is REALLY scary.
I have never offered myself for medical trials efore and after the debacle a couple of years ago that left the volunteers with serious health problems, I know I never will.
Other than that medical trial gone wrong, I cannot recall any news reports of other trials having gone wrong, it makes you wonder if people put down the well known one down as a one off and still go ahead with other trials for a bit of money.
Do you know which drugs were being tested? I'm glad you didn't take up the offer too!
