Uppers Downers & All Arounders

Uppers/Stimulants

Chapter 3

uppers stimulants
Uppers/Stimulants
  • In 1999 about
  • 1.7 million Americans used amphetamines for nonmedical reasons,
  • 4.2 million used cocaine,
  • 68 million smoked cigarettes,
  • 200 million drank coffee, tea, caffeinated soft drinks or an over-the-counter medication containing caffeine. (p. 83).
general classification
General Classification
  • Most people use stimulants in the form of:
    • Diet aids
    • Drugs to control hyperactivity
    • Coffee & Tea
    • Cigarettes
    • Caffeinated solf drinks
  • Stimulants are found in plants and in synthetic form
general effects
General Effects
  • Stimulants force the release of the energy chemicals (epinephrine and norepinephrine along with dopamine and serotonin)
  • Infuses the body with large amounts of extra energy before the body needs it
  • With heavy use the body’s energy supply is depleted leading to crash, withdrawal and depression
  • Crash and withdrawal occurs when energy supplies become depleted and body is left without reserves
general effects5
General Effects
  • All Stimulants activate chemical and electrical activity in central nervous system
    • Increases
      • Heart rate
      • Blood pressure
      • Respiration
    • Effects include
      • Activeness
      • Restlessness
    • Medical uses include treatment of obesity, narcolepsy and Attention-deficit/hyperactivity Disorder
general effects6
General Effects
  • Reward/reinforcement center is artificially over-stimulated
    • Rush of pleasure and strong sense of wellbeing
    • Often accompanied by no basic need for hunger, thirst or sex
  • Weight loss: stimulants fool the body into thinking it has satisfied hunger without eating
  • Cardiovascular side effects include constricted blood vessels, high blood pressure and sometimes arrhythmia
    • Chronic use weakens blood vessels and risk of stroke
general effects7
General Effects
  • Emotional & mental effects:
    • Initial release causes increase of confidence and euphoria
    • As use continues feeling of euphoria turn to irritability, paranoia, aggressiveness, depression
  • Tolerance & Addiction liability
    • Increases as body loses its ability to synthesize drugs
    • Can also develop with methamphetamine congeners, caffeine, nicotine and other mild stimulants
cocaine
COCAINE
  • Cocaine epidemics seem to occur every few generations
  • Hardcore use still strong in 2000’s
  • Cocaine is extracted from coca plant
    • 97% grown in South America
    • Colombian drug Cartels control cultivation and production
    • 2/3 of smuggling handled by drug artels in Mexico
    • U.S. consumes 70% of world’s cocaine trade
cocaine routes of administration
COCAINE: Routes of Administration
  • Chewing Leaf: Historically Native cultures
  • Drinking: Started in 1880’s in wine, coca cola, and patent medicine. Widely prescribed to womem
  • Injecting: Started after the invention of hypodermic needle in 1853
    • Intravenous use takes 15-30 seconds
    • Subcutaneous/intramuscular takes 3-5 minutes
  • Snorting: Self-limiting method
    • The more snorted, the less absorption due to constriction of capillaries in the nose
    • Destructive to nasal passages
cocaine routes of administration10
COCAINE: Routes of Administration
  • Mucosal & contact absorption
    • Can be absorbed through mucosal tissue in nose, mouth, rectum & vagina
    • Delivery method is also used for dental work, minor surgeries
  • Smoking:
    • First introduced in 1914, but high temperature was needed to keep cocaine cigarettes going
    • Mid-1970’s, cocaine hydrochloride was chemically altered into freebase
    • Fastest form to reach brain… Highly addictive
cocaine physical and mental effects
COCAINE: Physical and Mental Effects
  • Metabolism: Quickly metabolized and disappears faster than methamphetamine
  • Medical Use: Only naturally occurring local anesthetic
    • Used to numb nasal passages, eyes, throat, and chronic sores
  • Neurochemistry & Central Nervous System
    • Forces relase of norepinephrine, epinephrine and dopamine
    • Blocks re-absorption so more intense stimulation
    • Blocks 60-70% of dopamine reuptake
    • Too much dopamine can over stimulate brain’s fright center causing paranoia.
    • Excessive use causes insomnia, agitation and severe depression
cocaine physical and mental effects12
COCAINE: Physical and Mental Effects
  • Sexual Effects:
    • At low doses cocaine increases desire for sex and delay ejaculation
    • As use continues sexual dysfunction occurs
  • Aggression, violence & cocaethylene
    • Increases aggression & violence by disrupting inhibitory and fright centers of the brain
    • Cocathylene (metabolite when cocaine & alcohol is combined) induces greater agitation, euphoria and violence
      • Can also induce cardiac conduction abnormalities
cocaine physical and mental effects13
COCAINE: Physical and Mental Effects
  • Cardiovascular Effects
    • Can damage circulatory system
    • Raise blood pressure
    • Cause stroke (bursting of blood vessels in brain)
    • Cause heart damage
  • Neonatal Effects:
    • Transmitted within seconds to fetus
    • Increases chances for miscarriage, stroke, SIDS, respiratory ailments, mental delays & other abnormalities
    • Proper pre-natal and post natal treatment can hel cocaine babies
cocaine physical and mental effects14
COCAINE: Physical and Mental Effects
  • Tolerance: To the euphoric effect can begin to develop after first injection or smoking session
  • Withdrawal, Craving & relapse:
    • Major effects include anhedonia, lack of energy and intense craving
    • Typical cycle of compulsive use:
      • Bingeing to crashing to detox to resolutions of abstinence or treatment and relapsing 2-4 weeks later.
cocaine physical and mental effects15
COCAINE: Physical and Mental Effects
  • Overdose:
