Methamphetamine Drug Pharmacology
• A central nervous system stimulant that promotes the release of
neurotransmitters (dopamine, norepinephrine, and serotonin)
which control the brain’s messaging system for reward and
pleasure, sleep, appetite and mood
• 1500% more potent
than cocaine
• Purely a synthetic
compound
Faster, Faster until
the thrill of speed
overcomes the thrill
of death

Methamphetamine: Historical Aspects
• 1887: Amphetamine synthesized in Germany
• 1919: Methamphetamine synthesized in Japan
• 1930-40: Performance enhancer in WWII
• 1930s: Treatment for nasal passage inflammation, narcolepsy,
attention deficit disorder, obesity and fatigue
• 1960s: First recreational use
• 1970s: Legal production > 10 billion tablets ( ~1000X legitimate
medical use)
• 1970: Amphetamine/Methamphetamine classified as a
Schedule II drug
• 1980s: Illegal street forms popularized
(injected, inhaled or taken orally)
Methamphetamine Historical Aspects
• 1988: Smokable form (ice or glass) introduced from Hawaii
• Prior to 1990s: Manufacture controlled by the “White Motorcycle
Gangs” using phenyl-2-propanone (P2P)
• 1998: Federal Chemical Diversion and Trafficking Act placed
P2P under federal control
• 2003: Ephedrine (precursor) banned in its pure form in US
(increased restriction on pseudoephedrine)
• 2004: Identification required (in many states) to purchase
over-the-counter cold medications that contain
pseudoephedrine
• Today: 90% of the Methamphetamine available in United States
transported from Mexico
Current Methamphetamine Statistics
• The second most common illicit drug used worldwide
• 35 million regular users
• 12 million Americans have tried Methamphetamine
• 40% from 2000; 156% from 1996
• 1.5 million regular users
• 2003 National Survey: 5% of 8th graders and 15% of 12th
graders have tried Methamphetamine once in their lifetime
• > 17000 clandestine labs seized in United States in 2004 (100%
from 2002 and ~ 600% from previous decade)
• Over 50 recipes extracted from Internet Search
Oregon Statistics
• Number of Methamphetamine lab seizures in Oregon increased
from 67 in 1995 to 591 in 2001
• Oregon was third in the nation for number of children (241)
found at Methamphetamine labs during 2001-2002
• 2001: 2750 children (> half of all foster cases) were taken from
parents using or making Methamphetamine
• Between 4300 and 5350 children retrieved from
Methamphetamine homes have circulated in foster homes since
2001
• 2005: 472 labs and ~ 35 Kg Methamphetamine seized in state
of Oregon (7,000,000 dosage units)
Methamphetamine Addiction Statistics
• 100 people: alcoholic drink/day X 3 weeks = 8/100 addicted
• 100 people: oral or snort Methamphetamine or Cocaine daily X
3 weeks = 14/100 addicted
• 100 people: smoke or inject Methamphetamine twice = 90/100
addicted
• Methamphetamine addict that wants to quit: After 11 months of
not using, 100% of recovering addicts will use
Methamphetamine if offered
Methamphetamine Associated
Hospital Admissions (2002)
General Impact on Burn Centers
• Need for decontamination (treat chemical and thermal burns)
• Clandestine production (“cooking”) of Methamphetamine
involves > 30 different chemicals
• Increased incidence of trauma from explosions/projectiles
• Emergency medical personnel injury
• Withdrawal (higher sedation/narcotic use)
• Majority of patients uneducated and uninsured
• Extended length of stay
• Greater excision and graft failure
• Increased cost of treatment
