When there was that huge huricane that hit the Caribbean about ten years ago, I was in the hospital ER for a severe ovarian cyst, and they delayed giving me anything for the pain due to the fact that so much morphine and dilautid was made there and production came to a halt.
Them off-shoring our drugs was the stupidest thing they could have done.
