Drug
Any substance that, when taken into the human body, can impair the ability of the person to
operate a vehicle safely
Accommodation Reflex
The adjustment of the eyes for viewing at various distance. Meaning the pupils will automatically
constrict as objects move closer and dilate as objects move further away.
Addiction
Habitual, psychological, and physiological dependence on a substance beyond one's voluntary
control.
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.
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.
Analgesic
A drug that relieves or allays pain
Analog (of a Drug)
A chemical that is very similar to the drug, both in terms of molecular structure and in terms of
psychoative effects. For example, the drug Ketamine is an analog of PCP
Anesthetic
A drug that produces a general or local insensibility to pain and other sensation.
Antagonictic Effect
One mechanism of polydrug interaction. For a particular indicator of impairment, 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. Depending on how much each drug was taken, and on when they were taken ,
the suspect's pupils could be constricted, or dilated, or within the DRE Average range of pupil size.
, Arrhytmia
An abnormal heart rhythm
Artery
The strong, elastic blood vessels that carry blood away from the heart.
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.
Axon
The part of a neuron (nerve cell) that sends out a neurotransmitter.
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.
Blood Alcohol Concentration (BAC)
The percentage of alcohol in a person's blood.
Breath Alcohol Concentration (BrAC)
The percentage of alcohol in a person's blood, as measured by a breath testing device.
Bipolar Disorder
a condition characterized by alteration of manic and depressive states.
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.
Bradycardia
Abnormally slow heart rate.
Bradypnea
abnormally slow rate of breathing.
Bruxism
Grinding the teeth. This behavior is often seen in persons who are under the influence of Cocaine or
other CNS Stimulants.
Cannabis
This is the drug category that includes Marijuana. Marijuana comes primarily from the leaves of
certain species of Cannabis plants that grow readily all over the temperate zones of the earth.
Hashish is another drug in this category, and consists of the compressed leaves from female
Cannabis plants. The Active ingredient in both Marijuana and Hashish is a chemical called Delta-9
tetrahydrocannabinol, usually abbreviated to THC.
