Caffeine has been shown to decrease sleep latency and increase sleep fragmentation. It also suppresses REM sleep, but the effect is usually mild and short-lived. Valium (A) is a benzodiazepine that enhances the activity of GABA in the brain, leading to sedation, reduced anxiety, and muscle relaxation. It has been shown to increase total sleep time and slow-wave sleep, but it also reduces REM sleep. Alcohol (C) is a sedative-hypnotic that initially promotes sleep onset and slow-wave sleep, but later disrupts sleep maintenance and REM sleep. Marijuana (D) is a psychoactive drug that can affect sleep in different ways depending on the dose, route of administration, and frequency of use. Some studies have shown that marijuana can increase total sleep time and reduce REM sleep, while others have shown the opposite or no effect.
