According to your text, who is an excellent resource for you when you are unsure of your legal responsibilities with drugs or have uncertainties about drug therapy?

The answer is a pharmacist. These are healthcare professionals who practice pharmacy, the field of health sciences focusing on safe and effective medication use. A pharmacist is a part of the health care team directly involved with patient care. They go through university-level education to understand the biochemical mechanisms and actions of drugs, drug uses, therapeutic roles, side effects, potential drug interactions, and monitoring parameters. This is pair off with anatomy, physiology, and pathophysiology. Pharmacists understand and communicate this specialized knowledge to patients, physicians, and other health care providers.
