Well, let me explain.
1. I strongly advise my patients not to smoke. They do anyway, and they harm not only themselves but their family. Many of them die.
Of course, there is no comparison (it's "apples and oranges") with pertussis, but the only reason I can fathom for applying police state rules to immunization mandates is that non-compliance leads to social harm. My point was that tobacco smoking kills far more people than pertussis, so the social harm is worse -- and so we should logically exclude smokers from our practices.
2.You certainly can cheat on a drug test, and forge prescriptions --and many people do. I use drug tests as part of a conversation with patients -- they really aren't reliable, so I don't think they should be used to exclude people from the practice -- even if I catch them red-handed in full cheat mode. Not the first time, anyway -- and even then, it would only to be to tell them I can't prescribe any more schedule II drugs. Same with forgery. It's not an absolute "out" -- people try increasing the allowed refills, etc. If they were actually to forge prescriptions to obtain drugs to sell, that would likely be the end.
3. I don't suppose that pediatric patients normally would be considered threatening, so maybe you haven't experienced the difference between "rude" and "violent." ("Sticks and stones can break my bones, but calling names won't hurt me.") We have very rarely experienced truly violent people -- they are the only ones we actually exclude and forbid to return.
