"I don't know that I would even call it meth anymore"

Bozenko tinkered with his sample for two or three days. He realized it had been made with the P2P method, which he had not seen employed. Still, that was not the most startling aspect of the sample. There was something else about those few grams that, to Bozenko, heralded a changed world.

Among the drawbacks of the P2P method is that it produces two kinds of methamphetamine. One is known as d-methamphetamine, which is the stuff that makes you high. The other is l-methamphetamine, which makes the heart race but does little to the brain; it is waste product. Most cooks would likely want to get rid of the l-meth if they knew what it was. But separating the two is tricky, beyond the skills of most clandestine chemists. And without doing so, the resulting drug is inferior to ephedrine-based meth. It makes your heart hammer without offering as potent a high.

Bozenko’s sample contained mostly d-methamphetamine. Someone had removed most of the l-meth. “I’ve taken down labs in several continents,” Bozenko told me years later. No one in the criminal world, as far as he and his colleagues knew, had ever figured out how to separate d-meth from l-meth before.
