Mrs. Smith, a long time patient at your pharmacy, went on vacation to another country. While on her vacation, she realized she forgot her overthe-counter pain medication and visited a pharmacy to purchase some.

According to Mrs. Smith, the pharmacist was not licensed and sold her Tylenol with Codeine without the need for a prescription. Mrs. Smith is confused as to how this could happen. She asks you if licensure is so important, why is it not required in other countries. How would you explain this matter to Mrs. Smith?
