What types of poisons can be identified in forensic toxicology?

Forensic toxicology in the USA can identify various types of poisons, including heavy metals (e.g. arsenic, lead), drugs (e.g. opioids, cocaine), alcohol, and toxic gases (e.g. carbon monoxide). These substances can be detected through blood, urine, or tissue samples using analytical techniques such as chromatography and mass spectrometry. Understanding the basics of forensic toxicology is crucial in solving criminal cases and ensuring public safety.
