Eksangha,
Colchicine is a drug approved for oral use!
It has never been approved for IV use. Portland naturopath clinic was injecting the drug directly into the blood stream. That is #1 problem.
#2 problem: the drug was 10 times more concentrated then what it was suppose to be.
I think you have been jumping on conclusions here ... this incident has nothing to do with FDA.
If you take some common groceries ... and you press a juice and you pump it into people IV, you can kill them, ... without the need for groceries being FDA approved.
