Carey v. Population Services International, 431 U.S. 678 (1977), was a landmark decision of the U.S. Supreme Court in which the Court held that it was unconstitutional to prohibit anyone other than a licensed pharmacist to distribute nonprescription contraceptives to persons 16 years of age or over, to prohibit the distribution of nonprescription contraceptives by any adult to minors under 16 years of age, and to prohibit anyone, including licensed pharmacists, to advertise or display contraceptives.
