In what situation does delivery of a dangerous drug not constitute an offense?

Delivery of a dangerous drug not constituting an offense typically falls under situations where individuals are acting within the scope of their official duties. When someone is delivering a drug as part of their job—such as a licensed pharmacist distributing prescribed medications or a medical professional administering treatments—they are operating under legal frameworks and regulations that govern their profession. These roles are designed to ensure that drugs are delivered safely and appropriately, which is crucial for public health and safety.

In contrast, the other scenarios involve contexts where the delivery of a dangerous drug would likely violate laws or regulations. For instance, delivering drugs during food preparation could lead to contamination, thus posing health risks. Delivering for personal use or while under the influence raises concerns about the intent and the safety of the individual receiving the drugs. Both of these situations would typically result in legal consequences since they do not align with the controlled and regulated delivery that is expected in a professional setting.
