Eureka, formerly branded Eureka Vapor, is a multistate cannabis vape company founded in 2011 by two brothers and their father from New York. Its lineup runs on the PRELOAD reusable battery, RELOAD oil pods and the SLID3 rechargeable disposable, sold in California, Colorado, Connecticut, Massachusetts, New Jersey and New York.
Headset tracked the brand in 357 licensed dispensaries in August 2026, with vapor pens making up 96.5% of its sales.
Loyal to the Oil since 2011
Eureka didn't start in a boardroom, the company says. The founders set out to fix what early cannabis vaping got wrong, refining cleaner extraction methods at a time when most vape oil leaned on shortcuts and additives. From day one, the company says, the mission was to stay loyal to the oil, and Loyal to the Oil is still the motto.
As legalization spread, Eureka moved from underground standards to a regulated brand. The company says its oil is never cut or altered with MCT, PG, VG or vitamin E acetate. New York retailer Terp Bros describes the oil as CO2-extracted.
PRELOAD, RELOAD and one reusable battery
PRELOAD is the starter kit. It pairs a reusable, rechargeable battery with a preloaded 1- or 2-gram RELOAD pod, and Eureka pitches the reusable setup as eco-friendly. When the oil runs out, a fresh RELOAD goes on the same battery.
The company says every RELOAD fits every PRELOAD battery. Its Weedmaps product listings describe lab-tested ceramic hardware and what Eureka calls Heavy-Metal Free Technology.
Classic, Fusion and Premium pods
RELOAD pods come in three families. Classic uses distillate in cultivar names such as Mango Haze, Cherry Gelato and Blackberry Kush, and the Classic starter kits add Triple Diesel, Platinum Bubba and Mimosa. Premium uses small-batch live resin, with Super Skunk, Pink Champagne, Ghost Train Haze and Pound Cake on the menu.
Fusion pairs THC distillate with minor cannabinoids at fixed ratios. Very Berry and Coco Cloud run 4:1 and 2:1 THC to CBN. Tropical Twist is 6:1 THC to THCV, Lychee Lux 2:1 THC to CBD and Melon Madness 4:1 THC to CBC. Strawberry Clemonade and Sour Appleicious stack THC, CBG and THCV in 6:1:1 and 3:1:1 blends.
SLID3: three options, one device
SLID3 is a 3-gram rechargeable disposable built to switch between three options with the flick of a button. Eureka sells it in two lanes, Classic and Fusion, and lists nine versions in all.
Classic versions pair cultivars: Mango Haze x Triple Diesel, Grape Ape x Northern Lights and Mimosa x Jealousy, plus a sativa and indica split. Fusion versions match two blends, such as Very Berry x Coco Cloud, Tropical Twist x Citrus Splash and Concord Crush x Lychee Luxe.
Cannabis Cup hardware and the Cure pre-rolls
Eureka has cup history in Colorado. At High Times' Cannabis Cup Colorado 2019 in Denver, the Eureka Vapor UK Cheese pen took third place in Vape Pens and Cartridges. The same cup gave second place in Pre-Rolls to a Eureka Cure Wavy Gravy infused pre-roll.
The Cure name still covers the pre-roll side. Eureka's site lists infused pre-rolls in Cure Classic, Cure Fusion and Cure Premium ranges. Headset's August 2026 top sellers include live resin infused pre-rolls such as Long Island Diesel x Sour Diesel, Kushberry x GMO and Red Bullz x Tropicana Cookies.
Denver listing and California license
Eureka's JointCommerce wholesale listing, live since June 17, 2026, places the brand at 2190 S Jason Street in Denver.
In California, the brand's Weedmaps page carries manufacturing license DCC-10003537 for both adult-use and medical products. The Higher Origins license index, refreshed September 16, 2026, shows that license held by Light Box Leasing Corp., an active Type 6 manufacturer in Los Angeles County, issued June 24, 2019 and valid through June 24, 2027.
