**Step 1: Analyze Option 1 - "Aspirin belongs to narcotic analgesics."**
- Aspirin is classified as a non-narcotic analgesic. Narcotic analgesics are typically opioids that can be addictive and are used for severe pain relief. Since aspirin does not fall into this category, this statement is false.

**Step 2: Analyze Option 2 - "It is effective in relieving pain."**
- Aspirin is indeed effective in relieving pain. It is classified as an analgesic, which means it is specifically designed to alleviate pain. Therefore, this statement is true.

**Step 3: Analyze Option 3 - "It has anti-blood clotting action."**
- Aspirin is known for its anti-blood clotting properties. It inhibits platelet aggregation, which is why it is often used in low doses to prevent heart attacks and strokes. This statement is also true.

**Step 4: Analyze Option 4 - "It is a neurologically active drug."**
- Aspirin does have effects on the central nervous system, as it can influence pain perception and inflammation. Thus, it can be considered a neurologically active drug. This statement is true as well.

**Conclusion:**
After analyzing all the options, we find that the first statement, "Aspirin belongs to narcotic analgesics," is not true. Aspirin is a non-narcotic analgesic.

**Final Answer:**
The statement that is not true about aspirin is: "Aspirin belongs to narcotic analgesics."
