Accommodation Reflex - correct answer - 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 - correct answer - Habitual, psychological, and
physiological dependence on a substance beyond one's voluntary
control.
Addictive Effect - correct answer - 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 - correct answer - 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.

terms of psychoative effects. For example, the drug Ketamine is
an analog of PCP
Anesthetic - correct answer - A drug that produces a general or
local insensibility to pain and other sensation.
Antagonictic Effect - correct answer - 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.

Axon - correct answer - The part of a neuron (nerve cell) that
sends out a neurotransmitter.
Bad Trip - correct answer - 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) - correct answer - The

Breath Alcohol Concentration (BrAC) - correct answer - The
