The EZ Test Cocaine & Crack Cocaine is a single-step reagent kit that tells you within seconds whether the white powder in front of you actually contains cocaine — or whether your dealer's been creative with the cut. Drop a tiny sample into the ampoule, shake, watch the colour. Job done.
What the EZ Test Cocaine & Crack Cocaine actually checks
This is a presence test, not a purity test. The reagent inside the ampoule reacts with cocaine HCl and crack cocaine (cocaine base), turning a specific colour to confirm the substance is what your dealer claimed. It also flags two common substitutes you don't want: MDPV (a powerful cathinone stimulant that gets passed off as coke) and 5-MeO-MiPT (a tryptamine that has nothing to do with the experience you ordered).
If you want to know how much of the powder is cocaine versus filler, you need the EZ Test Cocaine Purity Test. If you want to identify the cutting agents themselves (lidocaine, phenacetin, levamisole and friends), grab the EZ Test Cocaine Cuts. Most people who care about what's in their bag end up buying all three over time — they answer different questions.
Why testing matters before you snort anything
Street cocaine is almost never pure. Customs seizures across Europe regularly report samples cut with levamisole (a veterinary deworming agent linked to agranulocytosis), phenacetin (an analgesic banned in many countries for kidney toxicity), and increasingly synthetic cathinones like MDPV that look identical to cocaine but hit completely differently. According to research on cocaine and enteric neuronal function (Frontiers, 2023), even pharmaceutical-grade cocaine has measurable physiological effects — adulterants stack additional, unpredictable risks on top.
The brutal honesty: you cannot tell by looking, smelling, or tasting. A 2015 paper on detecting cocaine use (PMC2564963) found that laboratory testing was the only reliable method of confirming presence — even trained users misidentified samples regularly. A two-minute reagent test isn't a lab, but it's the closest thing you'll get at home, and it costs less than the bag itself.
Which pack size to pick
| Pack | SKU | Best for |
|---|---|---|
| 1 test | SM0185 | One-off check on a single bag — try before you commit to a pack |
| 5 tests | SSDT0028 | Occasional weekend testing, or sharing with a couple of mates |
| 10 tests | SM0375 | Regular users, festival groups, or anyone who buys from rotating sources |
Each ampoule is single-use. If you buy from the same dealer regularly, test the first bag from every new batch — composition shifts more often than people think.

Complete your testing kit with the EZ Test Cocaine Purity Test to estimate how much actual cocaine is in your sample, and the EZ Test Cocaine Cuts to identify which adulterants are present. Together the three kits answer the only questions worth asking before you use: is it real, how much is real, and what's the rest?
How to use the EZ Test Cocaine & Crack Cocaine
- Open the ampoule carefully — the glass tip snaps off cleanly. Don't shake it before opening.
- Drop a tiny sample (match-head size, around 20mg) of the powder into the ampoule. Less is more — too much sample makes the colour hard to read.
- Close the ampoule with the supplied cap. Shake gently for a few seconds.
- Wait up to two minutes for the reaction to develop fully.
- Compare the resulting colour to the chart on the instruction sheet. Each compound (cocaine, MDPV, 5-MeO-MiPT) produces a distinct shade.
- Dispose of the used ampoule safely — the reagent is corrosive. Don't pour it down the sink with the lid off.
Honest limitations — what this test won't do
This kit confirms presence, not quantity. A positive cocaine result tells you there's cocaine in the sample — it does not tell you whether the sample is 10% cocaine and 90% levamisole, or 80% cocaine and 20% mannitol. The colour intensity gives you a rough hint, but it's not a purity reading.
It also won't catch every possible adulterant. Inert cuts like baking soda, glucose, or creatine don't react and simply dilute the powder. Active cuts like lidocaine (a numbing agent dealers add to mimic cocaine's freeze) don't show up here either — that's what the Cocaine Cuts kit is for. And as the manufacturer states clearly: this is not court-admissible. For that you need an accredited lab.
From our counter
We've been selling EZ Test kits since the early 2000s, and the question we get most often is "does it actually work?" Short answer: yes, the chemistry is well-established cobalt thiocyanate reagent work that's been used in forensic settings for decades. Long answer: the test does exactly what it says — it tells you whether cocaine is present and flags two specific impostors. It's not magic and it's not a lab, but for under a tenner per test you get information you cannot get any other way without sending the powder off in the post.
The customers who come back for the 10-pack are usually the ones who've had a bad night at least once. Testing before use is a habit, like wearing a seatbelt — most of the time nothing's wrong, but the one time something is, you'll be glad you bothered.
Frequently Asked Questions
How does the EZ Test Cocaine & Crack Cocaine work?
The ampoule contains a reagent that reacts with cocaine molecules and produces a colour change. Different compounds (cocaine, MDPV, 5-MeO-MiPT) trigger different colours, which you compare against the included chart. The whole reaction takes under two minutes.
Will this test tell me how pure my cocaine is?
No — this is a presence test, not a purity test. It confirms whether cocaine is in the sample and flags two common impostor compounds. For purity estimation, use the EZ Test Cocaine Purity Test. For identifying cutting agents, use the EZ Test Cocaine Cuts.
What is a cutting agent?
A cutting agent is anything added to a substance to bulk it out or mimic its effects. Common cocaine cuts include levamisole, phenacetin, lidocaine, benzocaine, caffeine, and inert sugars. Some are relatively harmless, others (levamisole especially) carry serious health risks.
Can the test detect fentanyl contamination?
No. This reagent is calibrated for cocaine, crack, MDPV and 5-MeO-MiPT only. If you're worried about fentanyl contamination, you need a dedicated fentanyl test strip — a separate product entirely.
Is the result court-admissible?
No. The manufacturer states clearly that for any formal or court-admissible result you need to submit your sample to an accredited laboratory. This is a personal harm-reduction tool, not a forensic instrument.
How long do the ampoules last?
Stored cool, dark, and dry the reagent stays stable for years. Heat and direct sunlight degrade it faster, so don't leave them on a windowsill. Discard any ampoule whose reagent has visibly changed colour before use.
