Final answer:
Legend drugs require a prescription and cannot legally be transferred without one. Transferring prescription medicines without proper authorization might lead to overdoses, similar to the misuse of illegal drugs.
Step-by-step explanation:
Legend drugs are prescription medications that are not available for purchase over the counter because they require a healthcare provider's authorization for use. The transfer of legend drugs without a prescription is generally prohibited by law. Such actions can result in serious legal consequences because they compromise drug safety and can lead to prescription or over-the-counter medicines being taken in doses that are too high, which might cause overdoses. It is important to use legend drugs only as directed by a healthcare provider to ensure that they are safe and effective. Moreover, not only prescription drugs but also illegal drugs pose overdose risks when misused.
