Question

Which of the following is not a stimulant?

• A. Amphetamines
• B. Cocaine
• C. Diamorphine
• D. Caffeine

Answer 1

The Correct Option is C

Diamorphine is a narcotic (opioid), not a stimulant, while amphetamines, cocaine, and caffeine are considered stimulants.

Answer 2

Diamorphine is a narcotic (opioid), not a stimulant. It is a potent pain-relieving drug derived from morphine and is often used medically for severe pain management. Diamorphine works by binding to opioid receptors in the brain, reducing pain perception and inducing a sense of euphoria, which can also lead to dependency and misuse if not properly regulated.

In contrast, amphetamines, cocaine, and caffeine are considered stimulants. Stimulants increase alertness, energy, and focus by enhancing the activity of neurotransmitters like dopamine and norepinephrine in the brain.

Amphetamines are often used to treat attention deficit hyperactivity disorder (ADHD) and narcolepsy, but they can be abused for their stimulating effects. Cocaine, a powerful stimulant, is illegal in many parts of the world due to its high potential for abuse and addiction. Caffeine, commonly found in coffee and tea, is the most widely consumed stimulant and is known for its mild stimulating effects, improving concentration and reducing fatigue.
