The Emetix-9 is a handheld aerosol dispersal unit containing a proprietary Lazarus Pharmaceutical compound designated LP-Emetic-9, a synthetic cholinomimetic agent that binds aggressively to gastrointestinal vagal receptors and the chemoreceptor trigger zone simultaneously. Onset of violent emesis occurs within four to eight seconds of inhalation or mucosal contact, followed by sustained nausea lasting fifteen to forty minutes depending on the subject's metabolic rate and augmentation status. The compound is colorless and carries only a faint medicinal odor — subjects often have no warning before incapacitation.

Developed originally as an emergency counter-toxin delivery mechanism for Lazarus field medics, the Emetix-9 was quietly repurposed and licensed to Meridian Municipal Security for crowd dispersal after internal trials demonstrated its near-universal effectiveness across augmented and baseline human subjects alike. Unlike OC-based sprays, Emetix-9 does not rely on pain compliance — it bypasses conscious resistance entirely by triggering an involuntary physiological cascade. A subject can be enraged, armored, and pain-tolerant and still be incapacitated within seconds.

The weapon is controversial within civil liberties advocacy circles because Lazarus holds the antidote — LP-Antag-9 — under a separate licensed product, and municipal contracts have been criticized for creating dependency on Lazarus supply chains for basic crowd control operations. Street medics operating in the Shelf refer to it grimly as 'the Lazarus tax.'
