Eureka has been making cannabis vape oil since 2011, long enough to remember what the first wave of cartridges got wrong. The whole promise fits into four words the brand has carried from the start: loyal to the oil. Everything in the lineup runs downstream of that one commitment.
About the brand
Eureka didn't start in a boardroom. It was founded in 2011 by two brothers and their father from New York, at a point when most vape oil leaned on shortcuts and additives that had no business in a cartridge. Their fix was to refine cleaner extraction and let the oil carry the product instead of the hardware.
That opening position — no cutting corners, no cutting the oil — turned out to be a durable one. As legalization spread state by state, Eureka moved with it, growing from an underground standard into a regulated brand without trading away the thing it built its name on.
What they make
The current lineup runs on three hardware platforms. PRELOAD is a reusable vape that takes a one- or two-gram RELOAD pod, so the device stays and only the pod gets swapped. RELOAD pods sell separately as refills for that same hardware, and SLID3 is the brand's standalone vape line.
Oil arrives as live resin or distillate, sorted into Classic, Fusion, and Premium tiers across the usual indica, hybrid, and sativa splits. Strain-specific releases include Pink Champagne, Pound Cake, Super Skunk, and Ghost Train Haze, while SLID3 runs blends like Grape Ape x Northern Lights and Mimosa x Jealousy.
Starter kits pair hardware with oil so a first purchase covers both: live resin Premium kits in indica, hybrid, and sativa, plus a distillate Fusion kit built around Very Berry. SLID3 leans on distillate classics, running blends such as Mango Haze x Triple Diesel next to its single-type options.
Fusion is where the ratio products live — Very Berry is built at 4:1 THC to CBN — and the newest addition is a three-gram rechargeable disposable that carries three flavors in one device.
The oil standard
The specification Eureka repeats hardest is about what the cartridge leaves out. The oil is never cut or altered with MCT, PG, VG, or Vitamin E Acetate, and the brand puts natural, pesticide-free oil at the center of the pitch. In a category where the ingredient list is usually the last thing anyone volunteers, that is the entire argument.
Where to find it
Eureka stocks shelves in six states: California, New York, Massachusetts, New Jersey, Connecticut, and Colorado, with a store locator covering each one. The brand also posts certificates of analysis for its New York products, so the lab paperwork behind the oil claim is there to read rather than merely asserted.
The High Rise take
Fifteen years in, a brand still leading with a line about not cutting its oil says more about the rest of the category than about itself. The PRELOAD design backs it up: keep the battery, replace only the pod. That is a quieter, more practical answer to vape waste than most of the disposables sitting next to it on the shelf.
