Depressants: Alcohol
• depresses the sympathetic nervous system.
• Alcohol tends to magnify all our tendencies.– Helpful people become more helpful, aggressive
more aggressive, sexual or sexual wannabes, more sexual.
• People become more self-disclosing.
Alcohol addicts
• Alcohol addicted people experience debilitating withdrawal symptoms– diarrhea, vomiting and hallucinations.
• Children of alcoholics can hold more liquor in their first experience than non COAs – suggests a genetic link.
Addiction correlates
• Risk taking boys more likely than others.• Mice have been bred to prefer alcohol to water.• Children of alcoholics have a 4X higher rates (about
60%)– Adopted Children of alcoholics still have 4x greater
rate.
• Age of first use correlates:– Under 15, 60% chance of alcohol problems– Over 21, drops to 7%.
• 2nd most used drug, about 20% of high schoolers.
• Active Ingredient is THC. Can be ingested by eating or smoking.
• Mild hallucinogen: distorts time perception, makes it particularly dangerous for driving.
Drugs and Consciousness Cheat Sheet
• Stimulants – speed up the activity of the CNS – Amphetamines– they increase the release and decrease the
removal of norepinephrine and dopamine at synapses causing increased activity at the receptors. They also reduce the activity of GABA
– Cocaine – like amphetamines– Caffeine – Nicotine – enhances the action of acetylcholine, increases
the release of glutamate, the brain’s primary excitatory neurotransmitter
– MDMA (methylenedioxymethamphetamine) or Ecstasy – similar to amphetamines
Drugs and Consciousness Cheat Sheet
• Depressants – reduce the activity of the CNS – they increase the availability of GABA , which reduces the activity of many neural circuits.– Alcohol– Tranquilizers– Barbiturates
• Opiates/narcotics – agonists for endorphins, HIGHLY addictive because they stimulate glutamate receptors and physically change the neuron structure – neuron comes to require the drug to function properly– Morphine - (an ingredient of opium which is derived from the poppy
plant)- Percodan, Demoral– Heroin – derived from morphine but 3x more powerful– Tylenol 3, codeine, percoset, vicodan, oxycotin, Advil
