Various embodiments of pharmaceutical product containers are disclosed. Each pharmaceutical product container includes a cap, a container body, and a locking mechanism. The locking mechanism is disposable from a locked state to an unlocked state at least when the cap is in a closed position relative to the container body (e.g., to define an enclosed space for pharmaceutical product). Once in the locked state and with the cap being in a closed position, the locking mechanism is unable to return to its unlocked state. Pharmaceutical product enclosed within the container with the locking mechanism being in its locked state may then be disposed of in any appropriate manner (e.g., discarded in the trash).
