What is the role of a toxicologist in forensic toxicology?

• A. To identify substances
• B. To determine the effects of the substance
• C. To preserve evidence
• D. To determine the date of collection

Answer: (B)

The main idea being tested is how a toxicologist uses analytical findings to interpret what a substance does in the body. In forensic toxicology, the focus isn’t only on what substances are present, but on what effects those substances would have on the person and how those effects relate to the case—such as impairment, driving ability, or cause of death. This involves assessing dose–response relationships, potential toxicity, interactions between substances, and timing of exposure, as well as considering factors like metabolism and postmortem changes that can influence interpretation. Preserving evidence and dating the collection are important responsibilities in forensic work, but they’re not the toxicologist’s primary role. Identifying substances is indeed part of the workflow, yet the key value a toxicologist adds is evaluating and explaining the actual or likely effects of those substances in the context of the case.
