I think it's just as silly to go into a business where you might have to do things you're morally against, as it is to get a job doing so.
You can't just walk up and buy a Walgreens pharmacy, the training alone to be a pharmacist is pretty intensive.
Why bother if you don't want to dispense certain pills? It's a waste of your own money (and our money, since many people get govt grants to do it)
Any pharmacy owner who does this deserves to go out of business in my opinion. I could see it leading to any one of the following one day:
"Oh, your kid needs Adderall? I'm not dispensing that. It's terrible stuff, and he's just a brat. ADHD is over-diagnosed and this drug is over perscribed. HE probably doesn't have it. If you were a better mother, he'd behave." [This has actually happened to my girlfriend's kid with a pharmacist they had never seen before, standing in for their normal one.]
"Oh, you need Valtrex? I'm not dispensing that. If you weren't a slut, you wouldn't have herpes."
"Oh, you need Atripla? I don't despense drugs to gays because Homosexuality is wrong."
Fistful: I think it's a stretch to link this to refusing to treat medicare patients. If a pharmacy or doctor takes federal money, perhaps, treating medicare patients can be a condition of that. Otherwise, I don't see it happening
