CSI: Miami2002

Lieutenant Horatio Caine:
MDP2P.

Tim Speedle:
Methylenedioxyphenyl-2-propanone. It's not really a recreational drug. It's not really anything

Lieutenant Horatio Caine:
Maybe that means he didn't mean to make it. Go with me here for a second, Speed. Now, if you sub in formic acid for nitric acid, you get Ecstasy, don't you?

Tim Speedle:
The cook screwed up.

Lieutenant Horatio Caine:
Right. But because the pills were white, he figured he could still sell them as X.

Tim Speedle:
So he replaces one ingredient along the chemical pathway to try and make something legal.

Lieutenant Horatio Caine:
Yes, he did, and ended up making a chemical so powerful, that its fumes could kill human beings.

Tim Speedle:
So what are we chasing, the fumes or the pills?

Lieutenant Horatio Caine:
We're chasing the cook.
