Question

The drugs that cause sleeplessness:

• A. LSD
• B. Barbiturates
• C. Amphetamines
• D. Benzodiazepines

Hint:

Amphetamines are stimulants that promote wakefulness and may cause insomnia.

Answer 1

The Correct Option is C

- Amphetamines are potent stimulants of the central nervous system.
- They increase alertness, concentration, and wakefulness—often resulting in sleeplessness or insomnia.
- These are sometimes misused as “wakefulness-promoting” drugs by students or shift workers.
Other options:
- LSD is a hallucinogen, not a direct stimulant.
- Barbiturates and Benzodiazepines are depressants; they are used to induce sleep and reduce anxiety.

Answer 2

Amphetamines are a class of powerful central nervous system stimulants that are commonly known to increase alertness, concentration, and energy levels. Due to their stimulating effects, one of the common side effects of amphetamines is sleeplessness or insomnia.

These drugs work by increasing the release of certain neurotransmitters such as dopamine and norepinephrine in the brain, which heighten arousal and alertness, making it difficult for individuals to fall asleep or maintain sleep.

Amphetamines are used medically to treat conditions like Attention Deficit Hyperactivity Disorder (ADHD) and narcolepsy, but when misused or taken in higher doses, they can severely disrupt normal sleep patterns.

Other stimulants like caffeine and certain decongestants can also cause sleeplessness, but amphetamines are particularly potent in this regard.

Therefore, among various drugs, amphetamines are specifically known for causing sleeplessness due to their strong stimulating effects on the central nervous system.
