Explain the importance of a forensic toxicologist.

A forensic toxicologist plays a crucial role in the investigation of crimes or incidents involving substances that can affect human health. Their primary function revolves around the analysis of biological samples, such as blood, urine, and tissues, to detect the presence of drugs, chemicals, and poisons. This analysis is vital for determining the cause of poisoning or overdose, which can be critical in legal cases where the cause of death or impairment needs to be established.

The expertise of a forensic toxicologist helps law enforcement and legal teams understand whether substances contributed to a person's behavior, health status, or death. By identifying specific toxins or drugs and their concentrations, forensic toxicologists can provide insights into circumstances surrounding an incident, potentially influencing investigations and court cases significantly. Their findings can help clarify whether a poisoning was accidental, intentional, or due to negligence, making their role integral to the justice process.
