I know someone who a while ago answered one of those ads to participate in a clinical trial, in this case, about depression.
They gave her a routine intake, a doctor interviewed her, and explained that they were comparing different ways to treat depression. In the end, the doctor had her try out an anti-depressant medication (without a prescription). He gave her a bunch of free samples of the stuff (about two month’s worth) and after a month (and more evaluation interviews) they both decided that it wasn’t really helping, so they parted ways.
Now she has a month of anti-depressant medication that she doesn’t need, and it turns out it’s the same name brand which her best friend uses–and for which her best friend pays a considerable price.
She wants to just give it to her friend. What do you think?
