D. Withdrawal syndrome is manifested when regular dose of drugs/alcohol is abruptly discontinued.

Answer

To determine which statement is incorrect regarding addiction and dependence on drugs and alcohol, let's analyze the concepts step by step.

### Step 1: Understand Addiction and Dependence
Addiction is characterized by a psychological and physical dependence on a substance, leading to compulsive behavior to seek and use that substance despite harmful consequences.

**Hint:** Addiction involves both psychological and physical components.

### Step 2: Withdrawal Symptoms
When a person who is dependent on drugs or alcohol suddenly stops using them, they experience withdrawal symptoms. These can include anxiety, tremors, nausea, and in severe cases, can lead to coma or death.

**Hint:** Withdrawal symptoms occur when the substance is abruptly discontinued.

### Step 3: Tolerance Development
With repeated use of drugs or alcohol, the body adapts to the substance, leading to tolerance. This means that over time, a person needs to consume a higher dose to achieve the same effect because the receptors in the body become less responsive.

**Hint:** Tolerance means needing more of the substance to feel the same effects.

### Step 4: Analyze the Statements
- **Statement about withdrawal symptoms:** Correct, as withdrawal symptoms manifest when the substance is stopped.
- **Statement about addiction being a psychological attachment:** Correct, as addiction does involve psychological factors.
- **Statement about tolerance levels decreasing:** Incorrect, because tolerance actually increases with repeated use, not decreases.
- **Statement about peer pressure contributing to addiction:** Correct, as peer pressure can influence an individual's decision to use drugs or alcohol.

### Conclusion
The incorrect statement regarding addiction and dependence on drugs and alcohol is the one that claims that the tolerance level of receptors decreases with repeated use. This is false; tolerance increases with continued substance use.

**Final Answer:** The incorrect statement is that the tolerance level of receptors decreases with repeated use.
