Assertion (A): Cocaine causes euphoria in man.
Reason (R): It is involved in the transport of dopamine.
Assertion (A): Cocaine causes euphoria in man.
Reason (R): It is involved in the transport of dopamine.
Show Hint
Cocaine blocks dopamine reuptake = sustained high.

- Both (A) and (R) are true. (R) is correct explanation for (A)
- Both (A) and (R) are true. (R) is not correct explanation for (A)
- (A) is true. But (R) is false
- (A) is false. But (R) is true
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Concept
Pharmacology of stimulants.
Step 2: Meaning
Mechanism of cocaine-induced euphoria.
Step 3: Analysis
Cocaine prevents the reuptake of dopamine, which is essentially interfering with the standard transport process of this neurotransmitter, resulting in prolonged stimulation of the brain's reward system.
Step 4: Conclusion
The alteration of dopamine transport is the primary reason for the observed euphoria.
Final Answer: (A)
