Study Notes

Psychoactive Drugs

Psychoactive drugs alter psychological activities by acting on the central nervous system.
Popular psychoactive substances include alcohol, caffeine, and cocaine.

MK-Ultra

MK-Ultra explored using LSD for mind control, war tactics against communism, and as a potential truth serum.

Drug Quick Reference Guide

Alcohol: Depressant; causes disinhibition and relaxation but can lead to coma or death.
Barbiturates: Depressant; promotes relaxation, but overdose can cause coma or death.
Caffeine: Stimulant; increases alertness but may lead to insomnia or anxiety.
Cocaine: Stimulant; induces euphoria but poses risks like heart attack or stroke.
Heroin: Depressant; creates intense pleasure but risks include liver disease and spontaneous abortion.
LSD: Hallucinogen; alters perception and mood, with potential long-lasting psychological effects.
Marijuana: Hallucinogen; can enhance sensory experiences but may impair memory and attention.
MDMA: Stimulant & hallucinogen; provides euphoria but risks include severe dehydration and possible seizures.
Methamphetamine: Stimulant; heightens energy, but leads to serious health issues including psychosis.
Opioids: Depressant; effective for pain relief, but poses overdose risks and respiratory problems.
Tobacco: Stimulant; promotes alertness but is linked to serious cardiovascular and cancer risks.

Consciousness

Consciousness is the state of being aware of something, whether internally or externally.
Automatic processing enables the brain to handle substantial sensory information without conscious effort.
Sensory overload may occur due to variations in automatic processing efficiency.

Altered States of Consciousness

Altered states can arise from drugs, sleep, hypnosis, meditation, sensory deprivation, or neurological abnormalities.

Sleep

REM sleep allows for dreaming, about 1–2 hours nightly, reflecting daily activities and emotions.
Sleep disturbances include narcolepsy, REM sleep behavior disorder, obstructive sleep apnea, insomnia, sleepwalking, and sleep terrors.
Narcolepsy: Characterized by excessive daytime sleepiness and sudden sleep attacks.
REM Sleep Behavior Disorder: Actions during dreams due to malfunctioning paralysis mechanism, posing injury risks.
Obstructive Sleep Apnea: Airway collapse during sleep leading to gasping and disrupted sleep.
Insomnia: Challenges in falling asleep or staying asleep, often leading to fatigue.
Sleepwalking: Complex behaviors during sleep with limited recall post-episode.
