HOSA Forensic Science: Toxicology and
Pharmacology Test Practice 2026
1. Toxicology The study of poisons
2. Postmortem Drug testing Drug testing with the goal of determining whether drugs were
the cause or contributing factor in a death
3. Work Place Drug Testing Testing job applicants and employees for illegal drugs in their
system
4. Absorption, Distribution, Me- ADME stands for
tabolism, and Excretion (The
stages in which a drug moves
through the body)
5. Opiates A large class of drugs distinguished by their ability to caused
euphoria and relieve pain. Includes: Oxycodone, Fentanyl, mor-
phine, heroin
6. Depressants Opiates are classified as...
7. Amphetamine A large class of drugs that creates an excitatory condition, wake-
fulness and euphoria. Includes: methamphetamines,
8. Stimulants Amphetamines are classified as...
9. Anorexic Appetite Supressent
10. Cocaine Substance derived from the erythroxylin cocoa plant that creates
and excitatory condition, state of wakefulness and euphoria
11. Cannabinoids Marijuana and other parts of the plant Cannabis with tetrahy-
drocannabinol (THC) as the active ingredient
12. Stimulant Cocaine is classified as...
13. Depressants Cannabinoids are classified as..

14. Polypharmacy A mixture of drugs
15. Gas Chromatography Gas flowing through a coated tube separates compounds by
their size, weight and chemical reactivity with the coating of the
tube or column
16. Cyanide Toxic chemical inhibits the electron transport chain in the mito-
chondria of cells. Most toxic in its gaseous state. Levels above
2500 ng/ml are fatal.
17. Carbon Monoxide Toxic gas that is formed in combustion. This gas binds to he-
moglobin more tightly than blood and prevents the blood from
carrying oxygen. Levels above 60% in the blood are fatal.
18. Methemoglobin Oxidized form of hemoglobin. The antidote to cyanide poison-
ing.
19. Immunoassays Tests using antibodies that react with a drug or substance that
recognizes the antibody
20. Thin-Layer Chromatography The use of a solvent that travels through a porous medium to
(TLC) separate compounds based on their chemical aflnity with the
solvent and the medium
21. GC-MS Acronym of Gas Chromatography with Mass Spectrometry
22. Mass Spectrometry Technique based on the detection of vaporized molecules and
their ionized fragments. The detection and display of the spectra
are based on the mass-to-charge ratios of the ions.
23. LC-MS Analytical instrument that combines a liquid chromatography
with a mass spectrometery. Detects more compounds than than
GC-MS
