Depressants

depressant: a drug that slows down your central nervous system (downers)
synergistic effect: taking two drugs simultaneously and getting a new effect
alcohol +
aspirin: internal bleeding in stomach
depressants: sedation, depression, coma
stimulants: increased risk-taking, cardiovascular stress, higher risk of overdose
marijuana: blackouts, hallucinations
hallucinogens: impaired cognition, dissociation
process
normal
relief of anxiety
disinhibition: lack of self-control or restraint leading to impulsion towards immediate gratification
hypnosis (sleep)
coma
death
examples
ethanol (alcohol)
C₂H₅OH
hydrogen bonds
dissolves in water/fat
processed by liver
effects
short-term
dizzy
drunk
fun
lose fear of embarrassment
happy/sad
poor decision-making
drinking under the influence (DUI)
vomiting
violent
long-term
liver damage/cancer
alcoholism: addiction to alcohol
tolerance
gout: alcohol/seafood builds up and causes arthritis
fetal alcohol syndrome
high blood pressure/stroke
determining if someone has oxygen
breathalyzer
oxidation-reduction reaction
chemical in breathalyzer reacts with alcohol and electrons move
blood test
blood alcohol content (BAC)
0.08% for adults
0.01% if under 21
spectroscopy on the blood
diazepam (Valium): for anxiety, tension (C₁₆H₁₃ClN₂O)
nitrazepam: seizures (C₁₅H₁₁N₃O₃)
fluoxetine (Prozac): antidepressant; increases serotonin production (C₁₇H₁₈F₃NO)
