FIS – Comprehensive Final Exam Study Guide and
Practice Questions
Toxicologists work with drugs or poisons - ANS✔✔ after ingestion (seized drug analysts deal
with drugs as physical evidence in its own right.)
Where are drugs primarily metabolized? - ANS✔✔ liver
What is an opiate? - ANS✔✔ A large class of drugs able to cause euphoria as well as relieve pain
A stimulant has all the following characteristics except...
Increased blood pressure
Reduced appetite
Reduced respiration
Elevated heart rate - ANS✔✔ Reduced respiration
"Free base" and "crack" cocaine differ in what manner? - ANS✔✔ They are generally identical.
Free base refers to the fact that the amine group within the cocaine has lost a hydrogen atom
(one definition of a base) ; crack cocaine refers to the crackling sound made when the material
is heated to the volatilization point.
What is the major active chemical in Marijuana? - ANS✔✔ Tetrahydrocannabinol (THC)
Which technique is a type of confirmatory analysis? - ANS✔✔ GC-MS (couples gas
chromatography to separate a sample into its component parts and mass spectroscopy to
produce structurally-based results of a particular molecule)
,The time at which a compound emerges from the gas chromatography or liquid
chromatography column is referred to as... - ANS✔✔ Retention time
Pharmacokinetics is best described as - ANS✔✔ How drugs and other complex molecules move
through the body
Postmortem redistribution refers to... - ANS✔✔ Concentration changes that occur after death
as drugs are absorbed from one bodily region into another
cocaine usually appears in large quantities in urine for up to three days following use. True or
false - ANS✔✔ False. Urine is typically analyzed for benzoylecgonine because cocaine only
appears in urine in small quantities for a brief period.
Which statement or statements is true of carbon monoxide - ANS✔✔ The presence of carbon
monoxide also causes oxygen to more tightly bind to hemoglobin
Blood levels of carbon monoxide-bound hemoglobin that exceed 60% are at great risk of death
(carbon monoxide tightly binds to hemoglobin itself, preventing oxygen transport to cells. it
makes the hemoglobin that is carrying oxygen much less likely to exchange it for carbon
dioxide.)
What is the chemical color test to confirm the presence of cannabinoids and THC? - ANS✔✔
Duquenois Levine test
The component of Lophophora diffusa that produces hallucinogenic effects is psilocin.. True or
false - ANS✔✔ False. Lopophora diffusa is a peyote cactus, the source of mescalin. Psilocin and
psilocybin are found in some species of mushroom.
What characteristic of different parts of a molecule does IR spectroscopy analyze when exposed
to IR light? - ANS✔✔ Vibrations
, Which members of the following list are schedule I drugs?
Heroin
LSD
Morphine
Codeine - ANS✔✔ Heroin
LSD
What kind of change does a drug cause once ingested? - ANS✔✔ Physiological
A new drug from China causes you to feel super energetic and happy. It makes it unsafe to drive
or operate machines like a toaster oven, and is commonly taken by young people. Doctors don't
know what to do with it. Given that inforamation, how should this new drug be scheduled? -
ANS✔✔ schedule 1
Ritalin and percosets are controlled substances, but people can use them legally as long as they
have a prescription from a medical doctor. True or false - ANS✔✔ true
Drugs primarily used to treat anxiety - ANS✔✔ Benzodiazepines
Pills (mostly) used for stimulant and happy-feeling purposes - ANS✔✔ Amphetamines
Natural or laboratory-produced drugs used for physical or emotional pain. - ANS✔✔ Opiates &
Opioids
Drugs which are used to alter perception or consciousness - ANS✔✔ Hallucinogens
Highly addictive stimulant drug, natural plant product. - ANS✔✔ Cocaine
