Question

which of the following is a primary concern of forensic toxicology?

• determining whether or not someone should lose weight
• determining whether or not someone takes vitamins on a regular basis
• determining whether or not someone has an iron deficiency
• determining whether the presence of controlled substances is legitimate

Explanation:

Forensic toxicology focuses on analyzing toxins/chemicals in biological samples, often related to controlled substances in legal/forensic contexts. The option "Determining whether the presence of controlled substances is legitimate" aligns with its role in investigating controlled substances in forensic cases. Other options (weight loss, vitamin intake, iron deficiency) relate to general health/nutrition, not forensic toxicology.

Answer:

Determining whether the presence of controlled substances is legitimate
