Answer

To answer the question "Sedatives differ from tranquilizers in," we will break down the differences between the two types of substances step by step.

### Step-by-Step Solution:

1. **Definition of Sedatives**:
- Sedatives are substances that have a hypnotic effect, meaning they promote sleep and reduce physiological activity. They lead to drowsiness or induce sleep.

2. **Definition of Tranquilizers**:
- Tranquilizers, on the other hand, are medications that primarily reduce anxiety and provide a calming effect on the brain. They do not induce sleep or drowsiness.

3. **Mechanism of Action**:
- Both sedatives and tranquilizers act on the Central Nervous System (CNS) and are classified as depressants. However, their effects differ significantly.

4. **Effects on Sleep**:
- The key difference is that sedatives induce sleep, while tranquilizers do not. Tranquilizers are designed to calm the mind without necessarily causing sleep.

5. **Common Misconceptions**:
- It is important to note that both sedatives and tranquilizers can lead to addiction, which is a common misconception that only one of them causes addiction.

6. **Conclusion**:
- Therefore, the main difference is that sedatives induce sleep, while tranquilizers primarily reduce anxiety without inducing sleep.

### Final Answer:
Sedatives differ from tranquilizers in that sedatives induce sleep while tranquilizers do not.
