A number of crimes involve toxins entering the body, such as poisoning, driving under the influence, and using illegal drugs. Detectives and criminal investigators seek help from forensic toxicologists to get the answers they need when they suspect that a chemical substance is related to a crime. 

Toxicologists study the presence and effects of toxins on living creatures, particularly humans. They may work for environmental groups, government and law enforcement agencies, or independent corporations and laboratories.

The term "forensics" means "of or having to do with a question of law." Forensic toxicologists are simply toxicologists who apply their knowledge to legal matters. They play a crucial role in solving crimes and helping to determine causes of death.

Forensic Toxicologist Duties & Responsibilities

Forensic toxicologists are responsible for investigating various substances to help solve crimes or detect unlawful contamination of the environment, food, or water supply. Their work includes:

  • Analyzing samples from bodily fluids and tissues to determine the presence or absence of harmful or intoxicating chemicals
  • Collecting and testing for harmful contaminants in food or the environment
  • Evaluating determinants and contributing factors in the cause and manner of death
  • Using chemical and biomedical instrumentation
  • Providing expert testimony
  • Working with medical examiners and coroners to help establish the role of substances related to the cause of death

In the law enforcement sphere, forensic toxicologists might work for criminal justice agencies, police departments, or government labs. They might look for poisons and toxins such as alcohol, drugs, metals, chemicals, and gases. Sometimes, the toxicologist's findings are the primary factor in determining whether a crime was committed. 

Toxicologists might also work for regulatory agencies such as the Environmental Protection Agency (EPA), the Food and Drug Administration (FDA), and poison control centers to help detect dangerous chemicals in the environment and the food and water supply.

Forensic Toxicologist Salary

Salaries for forensic toxicologists can vary widely and depend on one's work location and employer. The Bureau of Labor Statistics provides salary data for forensic science technicians, which is a closely related position. Here are some typical salaries:

  • Median Annual Salary: $60,590 ($29.13/hour)
  • Top 10% Annual Salary: $100,910 ($48.51/hour)
  • Bottom 10% Annual Salary: $36,630 ($17.61/hour)

Education, Training, and Certification

Forensic toxicologists must complete a bachelor's degree in forensic science, chemistry, clinical chemistry, or a related field through an institution that is accredited by the Forensic Science Education Programs Accrediting Commission (FEPAC). Although a graduate degree is not required, many toxicologists go on to pursue a higher degree to advance their career.

Coursework typically includes:

  • General toxicology
  • Principles of forensic science
  • Applied statistics
  • Toxic substances
  • Forensic medicine

To obtain professional certifications in forensic toxicology, you can contact the American Board of Toxicology (ABT) and the American Board of Forensic Toxicology (ABFT) for candidacy requirements.

Forensic Toxicologist Skills and Competencies

Forensic toxicologists require certain qualities to perform their job properly. In addition to having a fascination with the effects of chemicals on the human body, as well as the environment, they should have these traits:

  • Highly analytical to make accurate findings
  • Understanding of scientific practices and equipment
  • Patience, efficiency, and focus to gather results under pressure
  • Ability to follow procedures to achieve reliable results
  • Excellent written and verbal communication skills, as they may be called upon to provide courtroom testimony
  • Ability to handle emotionally upsetting details of a crime

Job Outlook

The field of forensic toxicology has grown to include drug and alcohol testing for employers and traffic enforcement officials, as well as testing animal samples for wildlife criminal investigators. In addition, this field has expanded to include testing for date rape drugs and performance-enhancing substances.

The BLS projects that employment of those in the forensic science field will grow by 14% through 2029, much faster than the average for all occupations. However, as a small field, the number of new jobs is estimated at only 2,400 through the next decade.

Work Environment

Forensic toxicologists perform most of their work in laboratories, where they may be standing for long periods of time. The lab is usually run by a private drug testing company, a medical examiner's office, or the police. You may also spend part of your day working out in the field, such as at a crime scene collecting samples.

Work Schedule

Expect to work 40 to 60 hours a week, as you manage a heavy workload under stringent deadlines. Hours need to be flexible, as forensic toxicologists are expected to be on call to collect and analyze evidence. In addition, working out in the field visiting crime scenes may also require extended or unusual hours.
