Question 1

Which of the following is a plant-derived hallucinogen?&#10;A) methamphetamine&#10;B) cocaine&#10;C) alcohol&#10;D) phencyclidine&#10;E) marijuana

Accepted Answer

Marijuana is a plant-derived hallucinogen, as it contains the psychoactive compound tetrahydrocannabinol (THC). Methamphetamine, cocaine, and phencyclidine are all synthetic drugs. Alcohol is a depressant and not a hallucinogen.

Question 2

Which of the following methods could be used to analyze drug evidence?&#10;A) HPLC&#10;B) TLC&#10;C) FT-IR&#10;D) Raman&#10;E) all of the above

Accepted Answer

All of the methods listed can be used to analyze drug evidence. HPLC and TLC are both chromatographic techniques that can separate and identify different components within a drug sample. FT-IR and Raman spectroscopy are both analytical techniques that can identify the chemical bonds and functional groups within a drug sample. Using a combination of these techniques can provide a more complete analysis and identification of the drug sample.

Question 3

The marijuana plant part with the highest THC content is the ____.&#10;A) flower&#10;B) stem&#10;C) leaves&#10;D) root

Accepted Answer

The highest concentration of THC is found in the flower, specifically the buds or "nugs". The stems, leaves, and roots contain much lower levels of THC.

Question 4

Which of the following drugs compounds has no accepted medical use?&#10;A) heroin&#10;B) codeine&#10;C) Valium&#10;D) Oxycodone&#10;E) secobarbital

Accepted Answer

Heroin is classified as a Schedule I drug, which means it has no accepted medical use and a high potential for abuse. The other options have accepted medical uses and are listed as Schedule II, III, or IV drugs.

Question 5

The Controlled Substances Act was amended in 1984 to allow the DEA administrator to ____.&#10;A) place a substance temporarily in Schedule I upon imminent hazard to public safety&#10;B) place a substance permanently in Schedule I upon imminent hazard to public safety&#10;C) place a substance temporarily in Schedule V upon imminent hazard to public safety&#10;D) place a substance permanently in Schedule V upon imminent hazard to public safety

Accepted Answer

The Controlled Substances Act was amended in 1984 to allow the DEA administrator to place a substance temporarily in Schedule I upon imminent hazard to public safety. This allows the DEA to take immediate action to prevent harm to the public without going through the lengthy process of permanently scheduling a substance.

Question 6

The principle drug found in coca leaves is known as ____.&#10;A) morphine&#10;B) caffeine&#10;C) cocaine&#10;D) codeine&#10;E) cannabis

Accepted Answer

The principle drug found in coca leaves is known as cocaine.

Question 7

The principle narcotic drug found in opium is known as ____.&#10;A) morphine&#10;B) caffeine&#10;C) OxyContin&#10;D) codeine&#10;E) Demerol

Accepted Answer

The principle narcotic drug found in opium is morphine.

Question 8

Which of the following is a confirmatory test that can differentiate close compounds such as amphetamines and methamphetamines?&#10;A) fluorescence&#10;B) NIK kits&#10;C) FT-IR spectroscopy&#10;D) light microscopy

Accepted Answer

FT-IR spectroscopy is a confirmatory test that can differentiate close compounds such as amphetamines and methamphetamines. It uses infrared light to identify the specific chemical bonds present in a sample, allowing for accurate identification of the substance.

Question 9

Which of the following is a plant-derived stimulant?&#10;A) methamphetamine&#10;B) cocaine&#10;C) alcohol&#10;D) phencyclidine&#10;E) marijuana

Accepted Answer

Cocaine is a plant-derived stimulant, specifically from the coca plant. Methamphetamine and phencyclidine (PCP) are synthetic stimulants, while alcohol and marijuana are depressants and hallucinogens, respectively.
