determining accidental deaths and suicides—and even for substance abuse while on the job.  A toxicologist may
be called on to test for anything from arsenic to poisoned gas to GHB to prescription drugs.

Middleberg of National Medical Services, the world's foremost independent toxicological testing laboratory,
which tests for more than 3,000 of those compounds. He suspects the number of poisonings each year are
