Answer

To determine which substance is not an opiate narcotic, we need to analyze the options provided: amphetamine, morphine, heroin, and pathidine.

### Step-by-Step Solution:

1. **Understand Opiate Narcotics**: Opiate narcotics are substances that are derived from the opium poppy and are primarily used for pain relief. Examples include morphine, heroin, and pathidine.

2. **Analyze Each Option**:
- **Morphine**: This is a well-known opiate narcotic used for pain relief. It is derived from the opium poppy.
- **Heroin**: This is also an opiate narcotic, synthesized from morphine and used for pain relief, though it is illegal in many places due to its addictive properties.
- **Pathidine**: This is another opiate narcotic, also known as meperidine, used for pain management.
- **Amphetamine**: This is not an opiate narcotic. It is a stimulant drug often used to treat attention deficit hyperactivity disorder (ADHD) and narcolepsy. It enhances alertness and sociability but does not have pain-relieving properties associated with opiate narcotics.
