Drug tests
by EZ Test
EZ Test Ketamine is a single-use reagent test kit that detects the presence of ketamine in powder, crystal, or pill form within minutes. Drop a tiny sample into the ampoule, give it a gentle shake, and the reagent changes colour to tell you what's actually in there. It's the fastest way to check your gear without sending it off to a lab — and it picks up more than just ketamine.
The EZ Test Ketamine comes in three variants. If you're testing a single batch, the 1-pack does the job. The 5-pack suits anyone who picks up from different sources over a few months. The 10-pack is the best value per test and stores for up to 3 years unopened — so there's no rush to use them all at once.
| Variant | Tests included | Best for |
|---|---|---|
| 1-pack (SM0186) | 1 test | One-off check |
| 5-pack (SSDT0032) | 5 tests | Regular testing over months |
| 10-pack (SM0376) | 10 tests | Stocking up — up to 3 years shelf life |
This reagent test kit identifies 6 substance groups from a single ampoule — not just ketamine. Each substance produces a distinct colour change, which you match against the included colour chart. Here's what it picks up:
| Substance | Colour reaction |
|---|---|
| Ketamine | Distinct colour change (see enclosed chart) |
| MDMA (Ecstasy) | Separate colour reaction |
| (Meth)Amphetamine | Separate colour reaction |
| 2-AI | Separate colour reaction |
| Methylphenidate / Ritalin | Separate colour reaction |
| PMA / PMMA | Separate colour reaction |
That last one — PMA/PMMA — is the one that matters most from a harm-reduction standpoint. PMA is significantly more toxic than MDMA at comparable doses and has been linked to fatalities across Europe. If your sample turns up PMA instead of what you expected, that's potentially life-saving information.
We've been selling drug testing kits since the early 2000s, and the single most common thing we hear is: "I trust my source." Fair enough. But your source has a source, and that person has a source. By the time a powder reaches your hand, it's been through multiple steps — and any one of them could have introduced a cut, a substitute, or something genuinely dangerous.
Ketamine in particular gets stretched with all sorts. We've seen customers come back surprised that their "ketamine" tested positive for amphetamine instead. Others have found no reaction at all — meaning whatever they had wasn't any of the 6 substances this kit detects, which is its own kind of red flag. A reagent test won't tell you purity or exact dosage, but it will tell you whether the substance you think you have is actually present. That's the minimum baseline before putting anything in your body.
The honest limitation: reagent tests are presumptive, not definitive. They confirm the presence of a substance, not its concentration. If you need exact purity numbers, you'd need a lab analysis — services like those offered by the Trimbos Institute in the Netherlands. But for a quick field check that takes 2 minutes and costs a fraction of a lab test, this is the best tool available.
One thing we always mention in the shop: do the test in decent lighting. Trying to read a colour chart by phone torch in a dim room is a recipe for misreading results. Natural daylight or a bright white lamp — that's what you want.
Ketamine has drawn serious clinical attention over the past decade, particularly for its potential in treating depression. According to a study published in PubMed, one hour after administration of ketamine treatment there was a notable and significant improvement in depression symptoms (PubMed ID: 38714931). And according to research published in PMC, the proposed clinical effects of ketamine and its mechanism of action in treatment-resistant depression involve various pharmacodynamic targets (PMC, 2023). A multicenter trial of esketamine in nasal spray form showed a robust antidepressant effect in patients with treatment-resistant depression, according to a review in PMC (2024).
On the safety side, reported side effects from clinical settings include drowsiness, nausea, feeling disoriented, and — at higher doses — dissociative symptoms. These are dose-dependent: clinical studies have typically used doses in the 100-200mg range per session for therapeutic purposes, with a maximum around 150mg staying within the safety window according to Bespoke Treatment. Recreational doses vary — Crew 2000 lists a common range of 30-75mg when insufflated.
None of this is a reason to skip testing. If anything, knowing that ketamine's effects are strongly dose-dependent makes it even more critical to confirm you actually have ketamine and not a substitute with a completely different dosing profile.
Reagent tests and laboratory analysis answer different questions. Here's a straight comparison so you know what you're getting:
| Feature | EZ Test Ketamine | Lab analysis |
|---|---|---|
| What it tells you | Presence/absence of 6 substance groups | Exact composition and purity percentage |
| Time to result | 2-5 minutes | Days to weeks |
| Where you can use it | Anywhere — pocket-sized | Must submit sample to facility |
| Accuracy | Presumptive — confirms presence, not concentration | Scientifically verified |
| Shelf life | Up to 3 years sealed | N/A |
| Cost | Low per test | Higher, varies by service |
For most situations, the EZ Test is the practical choice. It's what you can actually use on a Friday night before going out. Lab testing is the gold standard for certainty, but it's not something you can do on the spot. We'd say: use the reagent test as your first line of defence. If something looks off — no reaction, unexpected colour — consider sending a sample to a lab before going any further.
Testing for more than one substance? The EZ Test Marquis Reagent covers a broader range of compounds including opioids, and the EZ Test Cocaine Purity kit is worth grabbing if you're checking multiple substances in a session. Pair any test kit with the DanceSafe fentanyl test strips for an extra layer of screening — fentanyl contamination is increasingly turning up in substances where nobody expects it.
We've stocked EZ Test kits since they first appeared on the market, and they've become one of those products we genuinely push on people. Not because the margins are great — they're not — but because the alternative is guessing. And guessing with substances is how people end up in A&E.
The ampoules are glass, about the size of a small marker pen. They feel sturdy enough in the hand but they will break if you sit on them in a back pocket — we've had that reported more than once. Keep them in a hard case or at least an inner jacket pocket. The reagent inside has a faint chemical smell when you snap the ampoule open; nothing overpowering, but don't go sniffing it on purpose. The colour changes are clear and distinct under proper lighting. We've tested them ourselves against known samples and the results are consistent.
The 3-year shelf life is genuine — we've used kits close to expiry and they still produce reliable colour changes. Store them at room temperature away from direct sunlight, and they'll be ready when you need them.
It's a presumptive test — it reliably detects the presence of ketamine and 5 other substance groups, but it won't tell you purity or exact concentration. For that you'd need a lab. As a field test for confirming what's in your sample, it's the best pocket-sized option available.
No. This kit tests for ketamine, MDMA, (meth)amphetamine, 2-AI, methylphenidate, and PMA/PMMA. For fentanyl screening, you'd need a dedicated fentanyl test strip — we carry those separately.
Very little — roughly the size of a match head. A tiny scraping of powder or a small chip from a pill is enough. Using too much can actually make the colour harder to read.
The reagent changes colour within 2-5 minutes. Read the result under bright, preferably natural light for the clearest colour match against the included chart.
No. Each ampoule is single-use. Once you snap it open and add a sample, that test is done. The 5-pack or 10-pack gives you multiple individual ampoules for separate tests.
It means your sample doesn't contain any of the 6 substances this kit detects. That's a warning sign — your substance is either something else entirely or heavily cut with an unknown agent. We'd strongly recommend not taking it.
Keep them sealed in their foil pouches at room temperature, away from direct sunlight and moisture. Stored properly, they last up to 3 years from manufacture.
The reagent is corrosive and can stain or burn skin and clothing. Don't let it contact your skin — if it does, rinse immediately with water. Dispose of used ampoules carefully; don't pour the liquid down drains.
