Review Questions:
What are club drugs? What are some of the factors that support the use of club drugs? Club drugs are synthetic drugs that are typically used in bars, nightclubs, raves, and other gatherings. The settings of raves and nightclubs also support the use of these drugs.
What are presumptive tests? Why are they used? Screening tests are tests that are nonspecific and help a forensic scientist identify several particular drugs that the substance is likely to be.
What are color tests? Why are these tests used? Color tests are tests that involve introducing a chemical reagent to the drug and observing whether or not the material changes color. They are used to determine whether a drug is present at the scene.
What are microcrystalline tests? What information do they provide? Microcrystalline tests are tests that involve exposing the substance to a reagent and then examining the color and morphology of the crystals that form.
What is spectrophotometry? How can this be useful in identifying drugs? It identifies a particular drug, as the size, color, and shape of the crystals will di³er for each specific drug.
Critical Thinking Questions:
Why are forensic scientists an important part of drug cases? Forensic scientists are good at knowledge of chemicals, their structure and functions.
If you were a forensic scientist and you were called to a crime scene to see if drugs were present, what would you do to determine this? If I were a forensic scientist and was called to a crime scene to see if drugs were present in the crime scene, I would use a different kind of test to help me determine this, like for examplespectrophotometry tests, Microcrystalline test, and Color test. Because all of these tests would help me to determine if drugs were to be present in the crime scene.
Why is it important for forensic scientists to have as much information as possible about the place where a possible drug substance was found? It's important for a scientist to have as much information as possible about the place that the drug substance is found because many factors can contribute when identifying a type of drug and because there might have been some other substances with the drug and this could affect identifying the drug substance.
What are some of the difficulties in identifying particular drugs? Why is it important for forensic scientists to be able to identify particular drugs? The difficult part of identifying a particular drug is that some people may mix substances with other substances, legal or illegal. Some people use items in their houses to try and hind their drugs the best that they can, which will make it hard for you to find them and identify them.
