What kind of evidence does a forensic chemist analyze?

Forensic chemists focus on the analysis of chemical substances, which includes drugs, toxins, and other compounds that could be relevant to a criminal investigation. This specialization allows them to identify and quantify various materials that might be found at crime scenes, in bodily fluids, or on surfaces. Understanding the chemical composition and properties of these substances can provide valuable insights into the circumstances or causes surrounding a crime, such as drug overdoses or poisoning.

While biological evidence involves the analysis of organic materials, such as blood or DNA, this is not the primary focus of forensic chemists. Similarly, physical evidence like footprints and digital evidence from computers falls outside the realm of chemical analysis. Therefore, the option that correctly identifies the type of evidence analyzed by forensic chemists is that which pertains to chemical substances.
