Glossary of Terms
NARCOTIC ANALGESICS
One
of the seven drug categories. Narcotic analgesics include opium, the natural
alkaloids
of opium (such as morphine, codeine and thebaine), the derivatives of
opium
(such as heroin, dilaudid, oxycodone and percodan), and the synthetic
narcotics
(such as demerol and numorphan).
NERVE
A
cord-like fiber that carries messages either to or from the brain. For drug
evaluation
and classification purposes, a nerve can be pictured as a series of
"wire-like"
segments, with small spaces or gaps between the segments.
NEURON
A
nerve cell. The basic functional unit of a nerve. It contains a nucleus within
a
cell
body with one or more axons and dendrites.
NEUROTRANSMITTER
Chemicals
that pass from the axon of one nerve cell to the dendrite of the next
cell,
and that carry messages across the gap between the two nerve cells.
NULL EFFECT
One
mechanism of polydrug interaction. For a particular indicator of impairment,
two
drugs produce a null effect if neither of them affects that indicator. For
example,
PCP does not affect pupil size, and alcohol does not affect pupil size.
The
combination of PCP and alcohol produces a null effect on pupil size.

NYSTAGMUS
An
involuntary jerking of the eyes.
ONE LEG STAND (OLS)
A
divided attention field sobriety test. The third test administered in the SFST
battery.
"ON THE NOD"
A
semi-conscious state of deep relaxation. Typically induced by impairment due
to
Heroin or other narcotic analgesic. The suspect's eyelids droop, and chin rests
on
the chest. Suspect may appear to be asleep, but can be easily aroused and
will
respond to questions.
OVERLAPPING EFFECT
One
mechanism of polydrug interaction. For a particular indicator of impairment,
two
drugs produce an overlapping effect if one of them affects the indicator but
the
other doesn't. For example, cocaine dilates pupils while alcohol doesn't
affect
pupil size. The combination of cocaine and alcohol produces an
overlapping
effect on pupil size: the combination will cause the pupils to dilate.
