What Happened to Koi CBD Vape Juice?
Koi CBD vape juice was, for a while, the most recognisable CBD e-liquid in America. You cannot buy it any more — not from Koi, not in any strength, not in any flavour. Here is what actually happened, and what to do if that is the product you came looking for.
Discontinued. Koi’s 2026 catalogue contains 31 products and not one bottled e-liquid. The 250mg and 500mg vape juice bottles, the flavoured line and the unflavoured additive are all gone.
The nearest replacement Koi sells is the Balance Bar, a 500mg CBD disposable in seven flavours at $35.99.
What Koi CBD vape juice was
Koi launched in 2015 and spent its first years as, effectively, a vape company. The flagship was a CBD e-liquid sold in 250mg, 500mg and 1000mg bottles across a range of fruit and dessert flavours, plus an unflavoured additive you could mix into your own juice. It was marketed as containing 0% THC.
Around 2018 it was one of the most widely stocked CBD e-liquids in American vape and smoke shops, and it is the reason a large amount of search traffic still arrives at Koi looking for a product that no longer exists. Terms like “koi cbd vape juice”, “koi cbd liquid” and “koi cbd 250mg” still get searched every month.
Why it disappeared
Koi has never published an explanation, so what follows is the documented record rather than a statement from the company. Three things happened in close succession.
1. The 2019 drug test lawsuit
In April 2019 two plaintiffs sued Koi in Los Angeles Superior Court. One had bought three bottles of Koi CBD vape juice at $79.50 each on the strength of a 0% THC claim, tested positive for cannabinoids at work in June 2018, and was dismissed from her job. The complaint also alleged that Koi had made disease-treatment claims and had labelled an inhalable product as a dietary supplement, which FDA guidance does not permit.
2. The FDA warning letter
On 22 November 2019 the FDA sent Koi a warning letter naming eight products. “CBD Vape Oil” was on the list. The agency’s objection was to marketing claims rather than to the product itself, but an inhalable CBD product sitting inside an FDA enforcement action is a difficult thing to keep selling. A putative class action followed in December 2019 and was voluntarily dismissed without prejudice ten weeks later. The full record is in our Koi lawsuit explainer.
3. The category moved
Independently of any of that, bottled CBD e-liquid was losing to disposables across the whole market. Refillable vaping requires a device, a coil and a habit; a disposable requires none of them. Between 2019 and 2022 most CBD brands that sold e-liquid either dropped it or watched it shrink to a rounding error.
Any one of those three might not have killed the product. Together they made continuing to sell it an unattractive proposition.
What Koi sells instead
Two inhalable products, neither of which is a like-for-like replacement.
Koi Balance Bar CBD Vape
500mg of PRIZM broad-spectrum CBD in a disposable, seven flavours, $35.99 single or $79.99 for three. Non-intoxicating, THC listed at 0.001%, batch COA behind the QR code. It gives you the fast onset that made the e-liquid appealing, but you cannot refill it and you throw away a battery every 500mg.
THCA + THCP + Delta 9 Disposable
5g of intoxicating cannabinoids at $69.99. This will get you high and it will show on a drug test — the opposite of what Koi’s 0% THC vape juice was sold as. Not shipped to Arkansas, California, Idaho, Minnesota, Oregon or Rhode Island.
Our full Koi vape review ranks all seven Balance Bar flavours and covers both devices in detail.
If bottled e-liquid is specifically what you want
Be honest with yourself about which part of the old product you are trying to replace, because the answer changes what you should buy.
You wanted fast onset
The Balance Bar does this. Inhalation puts CBD to work in minutes rather than the 45 to 90 an edible takes. Buy the three-pack.
You wanted refillable
Koi cannot help you. No product in the current catalogue is refillable and none is planned as far as we can tell. You will need a different brand.
You wanted cheap CBD
Then vaping was never the efficient route. Koi’s Complete Full Spectrum gummies deliver CBD at 4.3¢ per milligram against the Balance Bar’s 7.2¢, and the Naturals tincture lets you titrate the dose precisely.
One more consideration worth stating plainly: the lawsuit that helped end this product was about someone failing a drug test on a CBD item labelled 0% THC. If your job tests you, read does hemp THC show up on a drug test before buying any inhalable hemp product from anyone.
FAQ
Does Koi still make CBD vape juice?
No. Koi’s 2026 catalogue contains 31 products and none of them is a bottled CBD e-liquid. The 250mg and 500mg bottles, the flavoured range and the unflavoured additive have all been discontinued.
Why was Koi CBD vape juice discontinued?
Koi has not published a reason. The documented context is a 2019 lawsuit brought by a consumer who failed a workplace drug test after buying it on a 0% THC claim, an FDA warning letter in November 2019 that named CBD Vape Oil among eight Koi products, and a market-wide shift from refillable e-liquid to disposables.
What replaced Koi CBD vape juice?
The Koi Balance Bar, a 500mg broad-spectrum CBD disposable in seven flavours at $35.99, or $79.99 for a three-pack. It is not refillable.
Where can I still buy Koi vape juice?
Nowhere legitimately new. Any listing you find is old stock of unknown age from a third-party seller, which means an expired or unverifiable COA. We would not buy an inhalable product on that basis.
Did Koi CBD vape juice really contain THC?
That was the allegation in the 2019 Los Angeles case, which was based on a positive workplace drug test. The case did not reach a finding on the point. Broad-spectrum CBD products are marketed as non-detect rather than absolute zero, and positive tests on such products are a known, documented risk across the category.
