Any sensible pharmacy, would carry most mainstream prescriptions because there is always some local doctor who will prescribe it.
Technically the pharmacy has a right to carry any legal substance they want. However, common sense would state that birth control would be at all pharmacies.
So, you admit that you posted false info. Also, 5% difference is huge, that is 5 less unwanted babies out of every 100. Meaning that is potentially 5 less aborted babies or babies in public adoption programs. Also, the sensible person would probably combine the pill with condom usage to achieve hypothetically a 97% effective rate.
Well, throughout the topic, no one has really seen it as infringing on the pharmacist's or pharmacy's rights. However, what this could do, it could free the rights of health care providers in some states from covering the pill. In turn, it could force a bunch of women to pay more for their BC or make it too expensive for them to afford. Therefore, it could infringe on the woman's right to plan a pregnancy when the time and situation are right for her and the baby.
