Years ago I was an OR nurse in a children's hospital. At the start of a case the surgeon said to the anesthesiologist, "Be sure to go easy with this one. This [I forget the name of that gas] is poison, you know." She replied "Everything I give is poison." That stuck with me. Get over it.
Mister, please disregard all posts of mine. Don't read them. You don't have the minimum critical thinking skills I would expect of someone who otherwise would "get" things I say. Even Kevin is a notch above you in understanding what I am trying to get across. Not agreeing necessarily (almost never), but comprehending.
I take a number of prescription medications. Everybody does. They are all "poison." Chemotherapy drugs are poison. Antibiotics are poison. Multivitamins are poison (they all have preservatives as well as the active ingredient to treat the condition). But they have beneficial effects on the majority of people who take them as prescribed. If not, they either don't work or cause side effects, or worse, are allergenic.
