Forensic toxicology is the scientific study of bodily fluids and tissues to detect and identify drugs, alcohol, and poisons. This field plays a crucial role in criminal investigations, helping to determine whether substances contributed to a person's death or impairment. Forensic toxicologists analyze samples using various techniques, such as mass spectrometry and gas chromatography. The findings from forensic toxicology can provide vital evidence in legal cases, including homicides, accidents, and drug-related offenses. By establishing the presence and concentration of substances, forensic toxicologists assist law enforcement and the judicial system in understanding the circumstances surrounding an incident.
