Final answer:
Prescription drugs require a prescription, unlike over-the-counter drugs, and are regulated strictly. Schedule I drugs are highly addictive and have severe health risks.
Explanation:
Prescription drugs are licensed medicines regulated by legislation that require a prescription before they can be obtained from a pharmacist. These drugs undergo extensive scrutiny by the FDA before approval, ensuring they are safe and effective when used as directed.
Unlike over-the-counter drugs that can be obtained without a prescription, prescription drugs have stricter regulations and are only accessible with a doctor's prescription to ensure proper usage and monitoring.
Schedule I drugs, on the other hand, are illegal substances with high addiction potential, severe health risks, and no recognized medical applications, placing them in the most restrictive category.
