Twitch is Chuza’s oldest working street stimulant, sold on corners long before Bumblebee ever showed up to compete with it. In its rawest form it’s nothing more than dried, bright green, sharply lobed leaves, dissolved straight under the tongue; refined, it reduces to a thick emerald liquid that smells unmistakably of spearmint no matter how it’s cut or cooked. A single dose sharpens the senses hard enough that background noise seems to drop away entirely – users describe being able to feel the people around them breathing – buying roughly ten minutes of genuinely enhanced reflexes before the body starts billing for it.

Cheap doesn’t mean safe. The habit locks in fast, and withdrawal starts within five days of regular use – shaking, dehydration, exhaustion, a hunger that doesn’t go away no matter how much gets eaten, and a full-body shudder that looks, from a distance, uncomfortably like someone sobbing. The Section 18 case everyone still remembers is Agent Branson’s: a rookie who leaned on Twitch to get through the worst riots the Section saw that year, hid it from his own partner, and turned up dead in his apartment months later with his stash still under the floorboards.

FILE NOTES

Twitch didn’t start as a street drug. The earliest recorded dosing method was surgical – small bladders implanted at the roof of the mouth, the user rubbing a tongue over them to release a measured hit. Whoever eventually took that idea to market skipped the surgery entirely: what actually moves through Chuza now comes in small, sealed glass bulbs, each one holding a single measured dose of the same emerald extract, meant to be bitten or cracked open and dissolved on the spot. Cheap to produce, easy to carry a dozen at once, and disposable enough that nobody’s ever caught holding a bottle.

A typical raid haul comes in exactly the way Section 18 logs it – a dozen or so bulbs packed into a small leather satchel, soft enough to carry without a telltale clink, easy to palm in a crowd. Evidence intake is blunt about the rest of it: count the bulbs, bag the satchel, and set one bulb aside on the front desk for whichever officer draws the short straw of confirming what it is.

Further out from the city, the supply looks nothing like a satchel of bulbs. Agents escorting a guide through the jungle toward Kenbro caught a mule train hauling burros loaded with a thick green-brown paste the locals call Basura – the raw, unprocessed concentrate Twitch is cut and diluted from before it ever reaches Chuza. Weight for weight it runs roughly three times the strength of the finished product, and whoever’s moving it plainly isn’t worried about running into Agents this far from a Section House.

STATUS: Filed under Equipment, contraband class. Illegal to possess without a physicker’s license, common enough that Section 18 processes a batch of it most weeks, and increasingly squeezed out of the market by something worse – Bumblebee, sold on the same corners as “the new Twitch” to anyone Twitch alone isn’t holding anymore. See Eskobar for who’s currently moving it.
