My college buddy stayed with me about 22 years ago while he went to med school, and then when he graduated he moved out. I found after he left a box of phenylephine with "PLACEBO" scribbled over it. That is to say, this has been known for at least 20 years. And yet this big, ok, medium-big, lie persists.
