Drug testing kits let you check what's actually in your powder, pill or tab before you decide what to do with it — and synthetic urine, saliva tests and detox products cover the other side of the equation. Azarius has stocked harm-reduction gear since 1999, and this category pulls together 25+ reagent tests, purity kits, urine test strips, saliva tests and sample-prep tools from EZ Test, CleanU, Kleaner and Dope or Nope. Buy what you need, know where you stand.
Buy Drug Test Kits — The Honest Buying Guide
Drug tests split into two jobs: checking your substance (reagent and purity kits) or checking yourself (urine and saliva tests). Pick the wrong one and you've wasted your money. The table below sorts it out in 30 seconds.
| What you want to know | Kit type | Good for | Example products |
|---|---|---|---|
| Is this substance what the dealer said? | Reagent identification test | First-time buyers checking a new batch | EZ Test Ecstasy, EZ Test Cocaine & Crack, Dope or Nope Drug Test |
| How pure is it? | Purity reagent test | Regular users gauging strength before dosing | EZ Test MDMA Purity, EZ Test Cocaine Purity, Purity Drug Test by Dope or Nope |
| Is my coke cut with something nasty? | Cutting agent test | Cocaine buyers worried about levamisole/phenacetin | EZ Test Cocaine Cuts |
| Exact THC/CBD percentages in my weed? | TLC cannabinoid kit | Growers, CBD buyers, medical users | Alpha-Cat Cannabinoid Test Mini Kit |
| Will I pass a urine screening? | Urine test strip | Anyone facing a workplace or medical urine test | Urine Drug Test (THC, cocaine, MDMA, amphetamine, meth) |
| Am I safe to drive after smoking? | Saliva test | Drivers in countries with roadside THC swabs | THC Saliva Test (3.5 ng/ml) |
| I'd rather not provide my own sample | Synthetic urine / prosthetic | People who want a backup plan | CleanUrin, Kleaner Urea, ScreenUrin Refill, ScreenyWeeny 6.0 |
Reagent Kits — Know What's in the Bag
Reagent kits are the cheapest, fastest way to check a substance before you take it. Drop a tiny speck into the phial, watch the colour change, compare against the chart. Most results land in under 90 seconds.
We carry the full EZ Test range — Ecstasy, Cocaine & Crack, Cocaine Cuts, Ketamine, LSD and Indoles, THC, and the purity versions for MDMA, cocaine and heroin. The Dope or Nope range adds 11 substance-specific kits (including GHB, psilocybin, opiates, 4-FA and crystal meth) plus a General Drug Test that screens for 11 compounds from a single ampoule. Buy single-shot vials or 5/10-packs depending on how often you test.
Honest limitation: reagent tests tell you if a substance IS present. They don't tell you everything that's also in there. A pill can react beautifully for MDMA and still contain PMA. If you want more confidence, combine an identification test with a purity test — that's why we stock both.
Urine and Saliva Tests — Check Yourself
Urine drug test strips use the same lab-grade immunoassay technology clinics use, just in a dip-strip format. Five minutes, clear line, done. We stock single-analyte strips for THC, cocaine, MDMA/XTC, amphetamine and methamphetamine, so you can order exactly what you need rather than a generic multi-panel.
For drivers, the CleanU THC Saliva Test is calibrated to 3.5 ng/ml — the same threshold used in most European roadside screenings. Swab, wait 20 minutes, read. If it's still showing positive, don't get behind the wheel. That's the whole point of buying one.
Synthetic Urine and Detox — The Backup Plan
CleanU and Kleaner make lab-formulated synthetic urine that matches the pH, creatinine, specific gravity and UV fluorescence labs check for. We stock the CleanUrin 25ml sachet, the ScreenUrin 80ml refill, the full ScreenUrin Set 2.0 with thermal bag, Kleaner Urea 30ml, and for anyone who needs a hand-free delivery method, the ScreenyWeeny 6.0 prosthetic in four skin tones (circumcised and uncircumcised).
Kleaner mouthwash is a separate beast — a herbal/alcohol rinse that freshens the mouth for about an hour and can interfere with saliva swab tests. Available in the regular bottle, a 6ml single-dose, or a spray format.
Cannabinoid Potency Testing — For Growers and CBD Buyers
The Alpha-Cat Cannabinoid Test Mini Kit uses thin-layer chromatography to quantify THC, CBD, THCV, CBG and CBC in your herb, hash, RSO or CBD extract. Eight tests per kit, claimed ±1% accuracy. This is the one growers buy when they want to know what their strain actually produced, and the one CBD shoppers buy when they want to verify a label.
How to Choose Your Drug Test Kit
First-time buyers: if you're testing a pill or powder you bought, start with a substance-specific reagent kit (EZ Test Ecstasy for pills, EZ Test Cocaine & Crack for white powder). One vial, one answer. Cheap insurance.
Regular users: pair an identification test with a purity test. EZ Test MDMA Purity and EZ Test Cocaine Purity give you a rough potency reading so you can dose accordingly — a 30% pill and an 80% pill are very different nights out.
Facing a screening: buy a urine test strip for the substance in question and test yourself first. If you come up positive and the screening matters, that's when the synthetic urine and ScreenyWeeny options become relevant. Don't improvise on the day.
Cocaine users specifically: get EZ Test Cocaine Cuts. Levamisole shows up in roughly 70-80% of European cocaine samples according to EMCDDA monitoring — it's an anti-worm medicine for horses and causes serious immune issues. Worth the few euros to know.
When in doubt, grab the Dope or Nope General Drug Test. One ampoule, 11 substances screened, clear colour chart. It's the kit we'd put in a festival bag.
Useful extras
- Plastic Pasteur Pipette (3ml) — disposable transfer tool for clean sample prep. Stops contamination between tests.
- TripStopper capsules — valerian-based calming capsules. Not a drug test, but we stock it alongside the kits because it's what people ask for when a test result isn't what they hoped.
- Open Your Eyes drops — herbal eye drops for red eyes. No vasoconstrictors, no rebound.
- Recover-E and Recoup-E — Happy Caps morning-after capsules. Recover-E for general recovery, Recoup-E for alcohol nights (dihydromyricetin-based).
Frequently Asked Questions
Do drug test kits actually work?
Yes — reagent kits use the same colorimetric chemistry police forensic labs use for presumptive testing, and urine strips use clinical-grade immunoassay. They're not as precise as a full lab GC-MS, but they're accurate enough to catch the common adulterants and tell you roughly what you're holding.
How long does THC stay detectable in urine?
Anywhere from 3 days for a one-off use to 30+ days for daily smokers. Fat-soluble THC metabolites store in body tissue and release slowly. If you need to be sure, buy a urine THC strip and test yourself a day or two before the real screening.
What's the difference between a reagent test and a purity test?
A reagent test tells you what's there (is this MDMA or something else?). A purity test tells you how much is there (is this pill 80mg or 180mg?). Serious users buy both and use them together.
Can labs detect synthetic urine?
Standard screening panels can't — CleanUrin, Kleaner Urea and ScreenUrin all match the key markers labs check (pH, creatinine, specific gravity, UV fluorescence). Advanced observed collections with temperature checks are harder, which is why the ScreenUrin Set 2.0 and ScreenyWeeny 6.0 include thermal packs to hit body temperature.
Which test should I buy for festival season?
Start with EZ Test Ecstasy (5-pack) and the Dope or Nope General Drug Test. Add EZ Test Cocaine Cuts if that's your thing. That combination covers most pills, most powders, and the nastier cutting agents for under the price of a festival dinner.
Do you ship drug test kits across the EU?
Yes — we ship the full testing range across the EU under free movement of goods. Orders placed before 16:00 CET on weekdays ship the same day from Amsterdam.
