What is a Forensic Toxicologist?
Forensic Toxicologists study the effect of exposure to toxic substances and chemicals on the human body. Forensic Toxicologists perform scientific tests on bodily fluids and tissue samples to identify any drugs or chemicals present in the body. They are responsible for knowing the dose required for a substance to affect humans, animals, and the environment – as well as the harmful effects. Qualified forensic toxicologists must have a comprehensive background in biology, chemistry, and the medical sciences to perform their duties.
Forensic Toxicology Expert witnesses are a valuable asset in the court of law – they provide an impartial, professional opinion on the validity of the evidence used within a trial. They cross-evaluate the sample to verify the correct testing method was used, check for contaminants, and use chain-of-custody documentation throughout the process to provide a full review of your case.
If your attorney believes there is an issue with the evidence used within your case, you will need to hire a forensic toxicology expert witness. They will validate the data to prevent the use of flawed evidence in the trial against you. A Forensic Toxicology Expert Witness will substantiate any claims made in court with scientific documentation and analysis, which will positively impact the trial’s outcome.
