Notes:_______________________________________________ 

The goal of this course is to ultimately increase deterrence of DWI violations; thereby reducing the number of crashes, deaths, and injuries caused by impaired drivers. 

Notes:_______________________________________________ 

Enforcement goals are to identify: 

• • Enforcement’s role in general DWI deterrence 
• • DWI detection phases, clues and techniques 
• • Requirements for organizing and presenting testimonial and documentary evidence    in DWI cases

SFST Master Glossary of Terms 

ACCOMMODATION REFLEX 

The adjustment of the eyes for viewing at various distances. 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. 

ADDITIVE EFFECT 

One mechanism of polydrug interaction.  For a particular indicator of impairment, two drugs produce an additive 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. 

AFFERENT NERVES 

See: "Sensory Nerves." 

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. 

ALVEOLAR BREATH -Breath from the deepest part of the lung. 

ANALGESIC 

A drug that relieves or allays pain. 

HS 178 R5/13 8 of 24 

ANALOG (of a drug) 

An analog of a drug is a chemical that is very similar to the drug, both in terms of molecular structure and in terms of psychoactive 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. 

ANTAGONISTIC 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 an antagonistic effect on pupil size. Depending on how much of each drug was taken, and on when they were taken, the suspect's pupils could be constricted, or dilated, or within the normal range of size. 

ARRHYTHMIA 

An abnormal heart rhythm. 

ARTERY 

The strong, elastic blood vessels that carry blood away the heart. 

ATAXIA 

A blocked ability to coordinate movements.  A staggering walk and poor balance may be caused by damage to the brain or spinal cord. This can be the result of trauma, birth defect, infection, tumor, or drug use. 

AUTONOMIC NERVE 

A motor nerve that carries messages to the muscles and organs that we do not consciously control. There are two kinds of autonomic nerves, the sympathetic nerves and parasympathetic nerves. 

AXON 

The part of a neuron (nerve cell) that sends out a neurotransmitter. 

BAC 

(Blood Alcohol Concentration) -The percentage of alcohol in a person’s blood. 

BrAC 

(Breath Alcohol Concentration) -The percentage of alcohol in a person’s blood as measured by a breath testing device.
