requires pharmacists to have either a prescription for certain meds
Kufauver-Harris amendment (1962)=
amendment to FDCA, → mandates pharmaceutical manufacturers to list complications
Drug abuse (1970)=
classifies the drugs used in medicine into 5 different schedules
Schedule 1 med:
Schedule 2 med:
Schedule 3 med:
Schedule 4 med:
schedule 5 med:
=never give, highest abuse potential
=high abuse ~dependence accepted med indi/s (codeine, morphine)
=less abuse potential low dependence (acetaminophen)
