Forensic toxicology is like being a science detective! It's when people use science to figure out what substances are in a person's body and how much of it is there. This can help figure out if someone was poisoned or if they took illegal drugs.
Forensic toxicologists use really fancy machines and special tests to figure out what's in a person's blood, pee, or hair. They can tell if someone took drugs like cocaine, heroin, or marijuana, or if someone got poisoned by something like chemicals or medicine.
Sometimes, forensic toxicology can even help figure out if someone was drinking alcohol or how much they drank. This is really important in figuring out if someone was driving under the influence (DUI) of alcohol.
In summary, forensic toxicology is when people use science to figure out what's in a person's body and how it got there.
