"While we can detect it, there's no way to measure how much is in the person's system," said Dr. Michael Bell, Palm Beach County's chief medical examiner, who added that the lab his office uses for toxicology reports only started testing for kratom a year ago. "We've seen it in only five cases, and that's not a lot compared to the other drugs we find. Whether or not we'll see more people with [kratom] in their systems; it's too early to tell."
