DRUG EVALUATION and CLASSIFICATION PROGRAM
  • Sgt. Pete Lamb
  • Richmond County Sheriff’s Office
2
DEC (DRE) Program
  • Origin
  • Los Angeles, 1970’s
  • LAPD Traffic Officer Dick Studdard
  • Drivers taken to hospitals to be evaluated by doctors
    • Drivers not prosecuted
  • Need to develop diagnostic procedures that officers could use to detect drug impairment
3
Development of DRE Program
  • Len Leeds (LAPD Narcotics Officer)
  • Research developed (medical classes & texts)
  • 1979 DEC Program officially recognized by LAPD
  • DEC Program evolved into a 3-step process using diagnostic procedures to determine:
4
The Three-Step
 Drug Evaluation Process
  • Step One:
    • Establish that the subject is impaired
  • Step Two:
    • Rule out medical impairment
  • Step Three:
    • Determine the category of drugs involved
5
Standardized and Systematic
  • Standardized process
    • Much like SFST’s
  • Systematic Process
    • 12 Steps
  • LAPD sought validation and support from NHTSA
6
Validation
  • Two phase validation
  • Laboratory Validation planned and conducted by researchers at Johns Hopkins University in Maryland in 1984
  • Drugs used:
    • Secobarbital (300mg)
    • Valium (15mg and 30mg)
    • Desoxyn (15mg and 30mg)
    • Marijuana
7
Johns Hopkins study
  • Neither volunteers or evaluators knew what was being taken (double blind)
  • Some volunteers took placebos
  • Results:  DREs correctly identified…
    • 95% of drug-free suspects as “not impaired”
    • 98.7% of suspects taking strong doses as “impaired”
    • The particular category of drugs 91.7%
    • MORE ACCURATE THAN PHYSICIANS TAKING PART IN THE STUDY
8
1985 Field Validation Study
  • 173 People arrested for DUI Drug charges
  • Blood toxicology done
  • DREs were correct in identifying at least one drug category
    • PCP 92% correctly identified

37
Methamphetamine
  • 2006 United Nations World Drug report calls Meth the MOST ABUSED DRUG ON EARTH.

  • Mean elimination half-life is 10 hours
  • Rapid onset of effects following intravenous or smoking administration
  • Duration of effects typically 4 to 8 hours but may last up to 12 hours
39
Pharmacodynamics of Meth
  • Methamphetamine’s effects are similar to Cocaine but onset is slower and duration is longer.
  • Unlike Cocaine, Methamphetamine does not have anesthetic properties


40
METHODS OF PRODUCTION
  • Red Phosphorus method
  • precursor chemicals are pseudoephedrine, iodine, and red phosphorus
  • Lithium/ammonia (Nazi) method
  • precursors pseudoephedrine, lithium metal, and anhydrous ammonia
41
METHAMPHETAMINE
  • In 2005, DEA agents seized a methamphetamine laboratory from a Smyrna residence and arrested three visiting undocumented guest workers from Mexico.
  • Agents seized over 10 pounds of crystal methamphetamine, 39 pounds of powdered methamphetamine, and several 30 to 55 gallon containers filled with liquid methamphetamine.
  • Agents discovered 24 garbage bags full of empty pseudoephedrine packages that would have held an estimated 240,000 tablets.
42

43
Tweaking
  • A meth binge typically lasts 3 – 15 days

  • User tries to keep high going by taking more and more of the drug.
  • The rush grows less extreme…the user can’t stay high
  • User grows irritable and has not slept for days
44
Tweaking (cont.)
  • Pupils begin returning to normal
  • Possible auditory hallucinations
  • User often behaves or reacts violently and is very dangerous to himself and others
  • Paranoia, delusions, anxiety
45
 
46
Dopamine Blues

  • Crystal Meth releases about 1,500% more dopamine
  • Meth kills dopamine producing cells in the brain
47
“Downside of Methamphetamine”
