In the context of controlled substances, a 'loss' is specifically signified by an event such as dispensing to the wrong person. This scenario is critical as it reflects a breakdown in the handling and distribution of controlled substances, which are tightly regulated due to their potential for abuse and misuse. When a controlled substance is mistakenly given to an unauthorized individual, it constitutes a loss not only in terms of physical inventory but also represents a potential public health risk and legality issue.

The other options do not fit the definition of a 'loss' as they either involve proper handling procedures or lawful activities. Scheduled disposal and returns to manufacturers are regulated processes that ensure controlled substances are handled according to legal requirements and do not represent a loss to the system. A lawful transfer indicates a legitimate movement of substances, which is also compliant with regulations. Therefore, the act of dispensing to the wrong person is the clear scenario that defines a 'loss' in relation to controlled substances.
