"That's what Jet is," Ellen says. "It's a stimulant, a nasty one. It's pretty popular with the violent and murdering types, too. Murphy, that ghoul I mentioned, was making an amped-up version using pre-War sugar cereal." She wrinkles her nose. "There's also Psycho, which was meant to make soldiers faster and more dangerous during the Resource Wars. People use that to get high these days. And Buffout is basically oral steroids that tend to induce psychotic berserker rages. It's pretty popular with raider types. Med-X you don't see so much in the field, though. That's synthetic opioid painkiller, so that's more the kind of thing people use back at base. It wouldn't surprise me at all if these guys had been using Jet before we ran across them."
