Power
Technically, you have quite a bit of power. You could fill a bottle with the wrong medication or prescribe an incorrect dosage and potentially be responsible for a patient's death. But that's not really the type of power you generally want to exercise. The greatest power comes in the research department, when you're contributing to advancements in the field of pharmacology. Not to be confused with "farm ecology," which is the study of pigs in #$%&.
