2. Toxicology of Alcohol Absorption into the blood stream
Distribution throughout the bodies water supply
Elimination by oxidation and excretion (average loss is 0.015% per hour)

3. Movement of Alcohol Esophogus to Stomach Small Intestine
Liver (process of destruction starts)
Moves to heart
Right Atrium and Right Ventricle ( very little O2)
Blood is pumped to lungs to be replenished with O2
Leaves through the nose and mouth

4. Breathalyzer Developed in 1954 Filled with Potassium dichromate
Any alcohol present dissolves the dichromate so we measure the amount of destruction

5. Field Sobriety Tests Series of psychophysical tests
Horizontal Gaze Nystagmus- eyes jerk at a 45 degree angle if you are .10% BAC
Walk and Turn
One Leg Stand
Alphabet

6. Alcohol Consumption and the Law
1992 Law was changed to .08% BAC legal limit
Truck and bus drivers legal limit is 0.04
Sweden’s legal limit is 0.02
It has been researched that you are 4 times more likely to get in an accident when you are a 0.08 than when you are sober.

7. pH Scale

8. Screening Tests
Thin Layer Chromatography- Identifies chemicals present in a mixture as it rises in a chamber
Gas Chromatography- separates mixtures individually into chemical compounds
Imunoassay- can detect small concentrations of drugs in bodily fluids and organs

9. Drug Recognition Expert
An officer who has received specialized training and been certified to evaluate suspects and determine:
1. If impaired
2. What drug is causing the impairment
3. What medication is causing the impairment

10. Narcotics Substances that bring relief from pain and produce sleep

13. Stimulants Any substance that stimulates the Central Nervous System
Examples include Crack, Cocaine, and Methamphetamine.

14. Color Tests
Many drugs yield certain colors when brought into contact with specific chemicals
Marijuana- Duquenois-Levine Color Test
The marijuana will turn purple when mixed with Ethyl Alcohol, Hydrochloric Acid, and Chloroform
