Replying to a message of Cindy Haglund to Bob Ackley:

 CH>>   Makes sense because blood can be kept just so long. Must be there's

 BA>> They don't want mine, either.  And they seem to be desperate for

 BA>> that's in it, I take six

 CH>  They don't want to have the drugs in the blood to give someone else. 
 CH> Not all drugs 'clear out' completely between doses?

Nope.  Plavix, for instance, takes about two weeks after the last dose before
it's considered to be gone.  And it's a one-a-day pill.

Note that they also don't want blood from cancer survivors (or cancer patients).
Presumably due to fear of spreading the problem - although mine was surgically
removed 11.5 years ago and there's been no trace of recurrence since.  The presence
of a prostate gland is detectable by a blood test, and while they won't say that my
PSA is zero, they will say that it's "not detectable within the limits
of the test."
