3
MEDICINES
  • Prevent disease
  • Vaccines (stimulate immune response)
  • Antitoxins (neutralize effect of toxins, i.e.
    tetanus)
  • Fight pathogens
  • Antibiotics fight bacteria, some bacteria become
    resistant
  • Antiviral (suppress virus), antifungal (suppress

4
MEDICINES
  • Relieve pain, analgesics, mild to very strong,
    aspirin to opiates, aspirin can be dangerous for
    children
  • Promote health
  • Allergy medicines
  • Body regulating, insulin, asthma meds,
    cardiovascular meds-BP, normalize HR, etc
  • Antidepressant, antipsychotic
  • Cancer treatment, chemotherapy

5
MEDICINES THE BODY
  • Medicines have different reactions in different
    people (body chemistry)
  • Side effects, not intended effect
  • Combinations with other meds or foods
  • Additive interaction, work together in a positive
    way anti-inflammatory muscle relaxant
  • Synergistic effect, two meds greater effects
  • Antagonistic interaction, work against (cancel
    effect

6
OTHER PROBLEMS
  • Tolerance, body becomes used to it, needing
    higher doses
  • Withdrawal, chemical dependence, mild to severe
  • Safety, FDA regulations, information on meds

  • Addiction, persistent, compulsive use, usually
    need help to quit

13
OTHER CONSEQUENCES
  • Individual, mental/emotional, physical and social
    health can be affected, inhibitions decrease,
    sexual activity, crime, violence
  • Legal, fines, jail time, etc
  • Family friends, changed behavior of user
  • Babies children, neglect, abuse, pregnant drug
    users, aborted fetus, birth defects, diseases,
    addiction
  • Cost to society, lost jobs, lost productivity

14
FAMOUS ODS
15
MORE ODS
16
ILLEGAL DRUGS
  • These drugs are not regulated for purity or
    strength
  • Marijuana

Hashish
17
MARIJUANA
  • Cannabis leaves, buds, flowers smoked, oils
    reduced to form hash or hashish
  • THC is active ingredient (stored in fat-drug
    tests)
  • Widely used, tends to be a step towards other
    drug use
  • Mood altering drug, produces dopamine
    (pleasurable sensation)
  • Psychologically addicting
  • More carcinogens than tobacco

MARIJUANA

    memory, reaction time, coordination, distorted
    sense of time, sight, touch, sound, (problems
    driving) decreased initiative ambition, lung
    irritation, heart lung damage, risk of lung
    cancer, weakened immune system, changed hormone
    levels, in females, increased testosterone, in
    males, lowered sperm count testosterone levels

19
INHALANTS
20
INHALANTS
  • Sniffed, inhaled, huffed
  • Go directly to brain, many kill brain cells
  • Solvents, aerosols, glues, sprays, paints,
    varnishes
  • Nitrates, nitrous oxide,
  • Brain damage, sometimes severe
  • Death
  • These are widely criticized even by pro drug
    people as being really stupid things to do

21
ANABOLIC-ANDROGENIC STEROIDS
22
STEROIDS
  • Synthetic substances similar to testosterone
    increasing muscle and male characteristics

    as much)
  • Legal consequences (sports organizations)
  • Organ failure, cancer, sexual dysfunction

23
PSYCHOACTIVE DRUGS

24
STIMULANTS
Amphetamines
Methamphetamine
Cocaine
25
STIMULANTS
  • Speed up central nervous system, some foods cause
    action, nicotine too
  • Some stimulants have medical uses
  • Amphetamines used in weight loss
  • Cocaine used in some surgeries
  • Cocaine negatives
  • Nausea, malnutrition
  • Chest pain, respiratory failure
  • Stroke, heart attack, seizure, death
  • Addiction, HIV (needles)

26
MORE NEGATIVES

  • Effects-surge of energy, self-confidence,
    euphoria, 20 minute-60 minute (-) duration
  • Topical anesthetic
  • Effects followed by emotional letdown

  • Cardiac arrest, respiratory failure, seizures,
    death

28
CRACK
  • Very pure form of cocaine, very intense
  • Strong chance of cardiac arrest/death

29
SPEED
  • Amphetamines-prescription, reduce fatigue,
    suppress appetite
  • Tolerance develops easily
  • Irregular heartbeat
  • Methamphetamine-has had some medical use
    (limited)
  • Made in home labs, quality is questionable, short
    term rush
  • Central nervous system damage, brain damage, HR
    increase blood pressure incr.

30
DEPRESSANTS
  • Sedatives, slow down central nervous system
  • Relax muscles, relieve tension, anxiety, slow
    heart rate, lower BP, slow breathing
  • Often deadly when combined with alcohol
  • Combining any depressants can cause extreme
    reactions even death

31
DEPRESSANTS
ltRohypnol
Barbiturates Tranquilizersgt
GHBgt
ltMethaqualone
32
MORE DEPRESSANTS
  • Barbiturates, sedative-hypnotic induces
    sleepiness, rarely used medically
  • Tranquillizers, reduce muscle activity,
    coordination, attention span, medically relieves
    anxiety, muscle spasms, sleeplessness,
    nervousness, can produce dependence/withdrawal
  • Rohypnol, club drug/date-rape produces
    unconsciousness (fatal doses)
  • GHB, date-rape (overdose easily)

33

Codeinegt
Morphinegt

    withdrawal

35
