Affiliate disclosure and scope
We use affiliate links on this site. This is one of the lowest scores we have given anything, and most of what follows concerns published research about the delta-8 category rather than this seller specifically — we are careful throughout to say which is which.
This article is informational only and is not medical advice. These are intoxicant products, none are FDA-approved, and you should speak to a licensed clinician before using any cannabinoid product. Checked 8 August 2026.
Read This First
Just Delta sells delta-8 THC gummies, cartridges, disposables and capsules, plus delta-10 and HHC products. Before anything about the seller, four things about delta-8 as a product category — all from published testing, none disputed.
- Delta-8 is chemically manufactured, not extracted. It is made by converting CBD under acidic conditions.
- In one university study of 27 products, none contained the amount stated on the label.
- Testing has found impurities at levels far beyond those declared on certificates of analysis, plus chemical species not on the certificates at all.
- Heavy metals including lead and mercury, and pesticides above legal limits, have been found in products across the category.
Those are findings about delta-8 generally, not about Just Delta. We have no testing data on this seller’s products specifically. But they are the context any purchase in this category sits inside, and no review that omitted them would be honest.
Delta-8 Is Manufactured, Not Extracted
This is the fact that explains everything else, and it is not widely understood by people buying these products.
Delta-8 THC occurs naturally only in trace amounts. There is nowhere near enough in hemp to extract commercially. So the delta-8 in every gummy and cartridge on the market is made by chemical synthesis — converting CBD to delta-8 under acidic conditions.
That reaction is not clean. It leaves conversion byproducts behind, and the published concern is not the delta-8 itself but everything else the reaction produces — compounds that have not been characterised, are not on the label, and in many cases were not looked for.
Compounding it: manufacturers performing this synthesis are unregulated, and commentary in the literature notes reports of potentially dangerous household products being used to facilitate the process. There is no pharmaceutical-grade requirement, no process validation, and no authority inspecting the conversion.
“Hemp-derived” is doing an enormous amount of work in this category’s marketing. The starting material is hemp. What you are consuming is the output of an unregulated chemical reaction.
What Independent Testing Has Found
Across this review series we have reported potency failures at several CBD brands — 12%, 13%, 16.68%, and in one case 40%. Those figures look almost quaint next to the delta-8 literature.
| Study finding | Result |
|---|---|
| University of Rochester Medical Center, 27 products | None contained the labelled amount |
| Separate analysis | 77% contained less delta-8 than advertised |
| 27 products, 10 brands, NMR / GC-MS / ICP-MS | None accurately labelled; 11 had unlabelled cutting agents |
| Contaminant analysis, 48 products | 15% had pesticides above state-permitted levels |
| Impurity profiling | Impurities far above declared levels; species absent from COAs; delta-9 THC; lead and mercury |
“None” is the word to sit with. Not most, not a majority — in two separate studies using different methods, not a single product tested matched its label. That is not a quality-control problem in the sense we have described elsewhere in this series. It is a description of a category where the number on the packet does not reliably correspond to anything.
The presence of undeclared delta-9 THC deserves separate mention, because it is the compound the entire legal structure of these products is built on avoiding. A delta-8 product containing unlabelled delta-9 is both a labelling failure and, potentially, a legal one for whoever is holding it.
Why “Check the COA” Is Not Enough Here
Throughout this review series our most consistent advice has been: read the certificate of analysis before you buy. It is good advice for CBD, and we have used it to separate brands that publish batch-level testing from those that do not.
For delta-8, it is much weaker protection, for two documented reasons.
- Testing found impurities at levels far exceeding what COAs declared, and species not on the certificate at all. A certificate can be accurate about what it measured and entirely silent about what it did not — and with an unregulated synthesis producing uncharacterised byproducts, nobody is necessarily looking for them.
- Reporting has described some companies faking lab results outright. A document you cannot verify against an accredited laboratory is a design asset, not evidence.
This is genuinely important and we want to be clear about it: the standard consumer-protection advice for this category does not work as well as it does elsewhere. A COA is still better than none, and a seller who publishes batch-matched certificates from a named accredited lab is doing more than one who does not. But “it has a COA” is not the reassurance in delta-8 that it is in CBD, and anyone telling you otherwise is skipping the literature.
What We Found About This Seller
Turning from the category to the company, with appropriate caution about the sources.
Just Delta is listed at an address in Fort Lauderdale, Florida. We found no FDA warning letter to the company, which is worth saying given the FDA has issued warning letters to a number of delta-8 sellers.
Algorithmic trust services rate the site cautiously. One gives a medium score of around 50.7, labelled “questionable”; another suggests it might be a scam based on several indicators.
We would not lean on those alone. Such services are automated heuristics — weighing domain age, traffic patterns and similar signals — not investigations, and they routinely misjudge legitimate small businesses. Treat them as a prompt to look harder, not as a finding.
More concerning are the specific customer accounts, because specificity is what distinguishes signal from an algorithm’s guess. Reported experiences include orders where a shipping label was created but no product ever shipped, missed delivery dates, and customer service not responding to emails.
“Label created, never shipped” is a particular pattern worth naming, because it produces a tracking number that appears to show progress while nothing moves — which delays the point at which a customer realises there is a problem and disputes the charge.
In fairness, the picture is not uniformly negative: one aggregator shows 3.8 out of 5 from 53 reviews, and earlier feedback described fast shipping and good service. We could not locate lab testing or COA information for this seller, which — given the section above — is the gap we would most want filled.
The 12 November 2026 Deadline
The Continuing Appropriations Act, 2026 (P.L. 119-37), signed November 2025, takes effect 12 November 2026. It measures the 0.3% threshold against total THC including THCA, bars hemp products containing more than 0.4 mg of THC, and targets synthetic cannabinoids such as delta-8 and unnatural ones such as HHC.
Just Delta’s catalogue is delta-8, delta-10 and HHC — that sentence almost verbatim. A 0.4mg per-container cap is far below the dose of any product sold here.
We are describing the statute as enacted and its stated effective date, not predicting how enforcement will run or what any company will do. But it is roughly three months away, and it is a poor moment to build a habit around this category.
Who Should Not Use These
- Anyone under 21.
- Anyone pregnant or breastfeeding.
- Anyone subject to drug testing — these products are detected, and testing has found undeclared delta-9 THC in delta-8 products.
- Anyone who will drive or operate machinery.
- Anyone with a personal or family history of psychosis or serious mental illness.
- Anyone with a significant cardiac condition.
- Anyone on prescription medication, without speaking to their prescriber.
- Anyone in a state where these compounds are restricted — several ban them outright, and a website displaying a product is not evidence of legality where you live.
Common effects include impaired coordination and concentration, dry mouth, raised heart rate, and at higher doses anxiety, paranoia and nausea. Edibles have delayed onset, which combined with unreliable labelling is the classic route to taking far more than intended — delta-8 exposures reported to US poison centres are a documented subject of published research.
If You Are Buying Anyway
Some readers will, and practical advice serves them better than a flat refusal.
- Check your state and locality first. Several states restrict or ban these compounds.
- Demand a batch-matched COA from a named, accredited laboratory, and check that it covers heavy metals, pesticides and residual solvents — not just cannabinoid content. Given the synthesis, the contaminant panel matters more here than the potency figure.
- Treat the stated dose as approximate. On the published evidence it may be substantially wrong in either direction. Start far lower than the label suggests.
- Wait much longer than you think you need to before taking more of an edible. Delayed onset plus unreliable dosing is how people end up in trouble.
- Never combine with alcohol or other sedatives.
- Pay by credit card. Given the fulfilment complaints described above, chargeback rights are worth having.
- Prefer a licensed dispensary if you have one. Regulated cannabis is tested under state mandate, accurately labelled by requirement, and not the product of an unregulated garage conversion.
If You Came From a Weight-Loss Search
This is not a weight-management product and works against that goal. Appetite stimulation is among the most consistently reported effects of THC and its analogues — it is the reason cannabis-derived appetite stimulants exist as prescription medicines.
Nothing here is FDA-approved for anything, nothing has been studied alongside GLP-1 medications, and if you are trying to eat less, this category makes that harder rather than easier.

Limitations of This Review
We have not purchased, used or tested any Just Delta product. Every testing finding cited here concerns the delta-8 category generally and none of it concerns this seller’s products. It is entirely possible Just Delta’s products are accurately labelled and clean; we have no data either way, and nothing in this review should be read as asserting that its products are mislabelled or contaminated.
Specific gaps: we could not locate COA or lab testing information for this seller, nor pricing, a list of excluded states, age verification arrangements, or return terms. Customer accounts are unverified individual reports, and complaint venues over-represent dissatisfied buyers. Algorithmic trust scores are automated heuristics, not investigations, and we have weighted them accordingly rather than treating them as findings — they frequently misjudge legitimate businesses.
The research findings are as reported in coverage of the underlying studies rather than papers we read in full, and the studies date from various points in a fast-moving market — product quality may have improved since. Regulatory information reflects the position as reported on 8 August 2026; state law varies and changes. None of this is medical or legal advice.
Frequently Asked Questions
What does Just Delta sell?
Intoxicating hemp-derived cannabinoid products: delta-8 THC gummies, vape cartridges and disposables, gel capsules, plus delta-10 THC gummies and HHC products. The company is listed at an address in Fort Lauderdale, Florida.
Where does delta-8 come from?
Not from the plant in any meaningful quantity. Delta-8 occurs naturally only in trace amounts, so commercial delta-8 is produced by chemical synthesis — converting CBD to delta-8 under acidic conditions. That conversion is what makes the product economically possible, and it is also the source of most of the concerns below, because the reaction leaves byproducts behind.
Are delta-8 products accurately labelled?
Published testing says frequently not, and the findings are stark. Researchers at the University of Rochester Medical Center analysed 27 delta-8 products and reported that none contained the amount listed on the label. Separate analysis found 77% contained less delta-8 than advertised. Another study of 27 products from 10 brands using NMR, GC-MS and ICP-MS reported none had accurate labelling, with 11 containing unlabelled cutting agents. These are findings about the category, not about any one seller.
What contaminants have been found?
Reported findings across the category include impurities present at concentrations far beyond what certificates of analysis declared, chemical species not listed on those certificates at all, delta-9 THC, and heavy metals including lead and mercury. One analysis found 7 of 48 products — about 15% — contained pesticides at levels above what state law permits. Commentary also notes that manufacturers synthesising delta-8 are unregulated and have been reported using household chemicals in the process.
Can I just check the certificate of analysis?
That is the advice we give for almost every other product category, and for delta-8 specifically it is weaker than it sounds. Testing has found impurities at levels far exceeding what COAs declared, and species absent from the certificate entirely — so a COA can be accurate about what it measured and silent about what it did not. Reporting has also described some companies faking lab results outright. A certificate is still better than nothing, but it is not the assurance here that it is elsewhere.
What happens on 12 November 2026?
The Continuing Appropriations Act, 2026 (P.L. 119-37) takes effect. It measures the 0.3% hemp threshold against total THC including THCA, bars hemp products containing more than 0.4 mg of THC, and targets synthetic cannabinoids such as delta-8 and unnatural ones such as HHC. Just Delta's catalogue — delta-8, delta-10 and HHC — is that description almost exactly. We are stating the statute as enacted and its effective date, not predicting enforcement.
What did you find about this specific seller?
A mixed and somewhat concerning picture. Algorithmic trust services rate the site cautiously — one gives a medium score of about 50.7 labelled "questionable" and another suggests it might be a scam based on several indicators. Those services are automated heuristics rather than investigations and frequently misjudge legitimate businesses, so we would not rely on them alone. More concerning are specific customer accounts describing orders where a shipping label was created but no product shipped, missed delivery dates and unanswered emails. One aggregator shows 3.8 out of 5 from 53 reviews, so the picture is not uniformly negative. We found no FDA warning letter to this company.
Will these show on a drug test?
Yes. Delta-8, delta-10 and HHC products are detected by standard THC screens, and testing has additionally found delta-9 THC present in delta-8 products that did not declare it. If you are subject to workplace, athletic or court-ordered testing, do not use these.
Verdict
1.9 / 5
A product category where two separate studies found that not one tested item matched its label, built on an unregulated chemical synthesis, facing a federal deadline in November — sold by a seller whose fulfilment complaints and absent testing information we could not resolve.
Most of this score is about delta-8 rather than Just Delta, and we have tried to keep those separate throughout. But the category evidence is difficult to look past. Researchers at the University of Rochester analysed 27 products and reported that none contained the labelled amount. A separate study of 27 products across 10 brands found none accurately labelled, with 11 containing unlabelled cutting agents. Across this series we have criticised CBD brands for 12% and 40% variances. This is a category where the label frequently does not correspond to the contents at all.
The reason sits in the chemistry. Delta-8 does not occur in useful quantities in the plant — it is synthesised from CBD in an unregulated conversion that leaves uncharacterised byproducts behind, performed by manufacturers subject to no process oversight. “Hemp-derived” describes the starting material and not the thing in the packet.
And the usual defence does not hold. We tell readers to check the certificate of analysis on almost every product we review. Here, testing has found impurities far above declared levels and compounds absent from the certificates entirely, and reporting describes some companies faking results. A COA is still better than nothing and it is not the protection it is elsewhere.
On the seller specifically we are more cautious, because our sources are weaker. Algorithmic trust scores are guesses, not investigations. But customer accounts of shipping labels created with no product shipped and unanswered emails are specific, and we could not find lab testing information at all — which, given everything above, is the one thing that might have counted in the seller’s favour.
We would not buy this. If you want cannabinoids and have a licensed dispensary available, it is tested under state mandate and labelled by requirement — which is the entire problem this category has. And if you buy here anyway, pay by credit card, demand a batch-matched accredited COA covering contaminants, and treat the dose on the packet as a rough estimate.
Treat the Label as an Estimate
We do not recommend this purchase. If you make it anyway: check your state and locality, pay by credit card given the fulfilment complaints, insist on a batch-matched certificate from a named accredited lab covering heavy metals and pesticides rather than potency alone, start far below the stated dose, and wait considerably longer than feels necessary before taking more of an edible. A licensed dispensary, where available, sells products tested and labelled under state mandate. This page is informational only and is not medical or legal advice.
