 So Cato says the decline is likely because many family planning clinics with abortion services, they closed after the bans. But those were the same clinics that offered family planning and reproductive health. That's where people got these prescriptions. The other reason for the decline in prescriptions may be just confusion over what is legal. A study last year by the Kaiser Family Foundation found more than half of the women surveyed believed that Plan B was illegal because of their state's abortion ban.
