Question

Consider the following statements Statement I: Use of cocaine produces a sense of euphoria and increased energy Statement II: Excessive use of cocaine causes hallucinations

• A. Both statement I and statement II are true
• B. Both statement I and statement II are false
• C. Statement I is true, but statement II is false
• D. Statement I is false, but statement II is true

Hint:

Cocaine is a CNS stimulant. It initially produces euphoria and increased energy but chronic abuse may result in hallucinations and severe psychological disorders.

Answer 1

The Correct Option is A

Concept: Cocaine is a powerful natural stimulant obtained from the leaves of Erythroxylum coca. It acts primarily on the central nervous system by interfering with the reuptake of neurotransmitters such as dopamine. Because of this action, cocaine produces intense stimulation, excitement and a temporary feeling of well-being.

Step 1: Examine Statement I. Cocaine stimulates the central nervous system and increases dopamine levels in synapses. As a result, the user experiences:
• Euphoria
• Increased alertness
• Enhanced energy
• Increased confidence Therefore Statement I is correct.

Step 2: Examine Statement II. Prolonged or excessive use of cocaine can produce several psychological disturbances including:
• Hallucinations
• Delusions
• Anxiety
• Paranoia Hence Statement II is also correct.

Step 3: Final conclusion. Both statements are true. \[ \boxed{\text{Both Statement I and Statement II are true}} \] Hence option (A) is correct.
