1. Drug Any substance that, when taken into the human body, can impair the ability of the
person to operate a vehicle safely
2. Accommodation The adjustment of the eyes for viewing at various distance. Meaning the pupils will
Reflex automatically constrict as objects move closer and dilate as objects move further
away.
3. Addiction Habitual, psychological, and physiological dependence on a substance beyond
one's voluntary control.
4. Addictive Effect One mechanism of polydrug interaction. For a particular indicator of impairment,
two drugs produce an addictive effect if they both affect the indicator in the same
way. For Example, cocaine elevates pulse rate and PCP also elevates pulse rate.
The combination of Cocaine and PCP produces an additive effect on pulse rate.
5. Alkaloid A chemical that is found in, and can be physically extracted from, some substance.
For example, Morphine is a natural alkaloid of Opium. It does not require a
chemical reaction to produce Morphine from Opium.
6. Analgesic A drug that relieves or allays pain
7. Analog (of a A chemical that is very similar to the drug, both in terms of molecular structure
Drug) and in terms of psychoative effects. For example, the drug Ketamine is an analog
of PCP
8. Anesthetic A drug that produces a general or local insensibility to pain and other sensation.
9. Antagonictic Ef- One mechanism of polydrug interaction. For a particular indicator of impairment,
fect two drugs produce an antagonistic effect if they affect the indicator in opposite
ways. For example, Heroin constricts pupils while cocaine dilates pupils. The
combination of Heroin and Cocaine produces antagonistic effect on pupil size.

the suspect's pupils could be constricted, or dilated, or within the DRE Average

10. Arrhytmia An abnormal heart rhythm
11. Artery The strong, elastic blood vessels that carry blood away from the heart.
12. Autonomic Nerve A motor nerve that carries messages to the muscles and organs that we do not
consciously control. There are 2 kinds of autonomic nerves, the sympathetic nerves
and parasympathetic nerves.
13. Axon The part of a neuron (nerve cell) that sends out a neurotransmitter.
14. Bad Trip A hallucination where the user becomes panic-stricken by what he/she is seeing
or hearing, and may become uncontrollably excited, or even try to flee from the
terror.
15. Blood Alco- The percentage of alcohol in a person's blood.
hol Concentra-
tion (BAC)
16. Breath Alco- The percentage of alcohol in a person's blood, as measured by a breath testing
hol Concentra- device.
tion (BrAC)
17. Bipolar Disorder a condition characterized by alteration of manic and depressive states.
18. Blood Pressure The force exerted by blood on the walls of the arteries. Blood pressure changes
continuously, as the heart cycles between contraction and expansion.
19. Bradycardia Abnormally slow heart rate.
20. Bradypnea abnormally slow rate of breathing.
