How to Test Cocaine for Purity and Safety (2026 Guide)
⚠️ Testing Cocaine? Start Here
Most cocaine is cut with dangerous adulterants. Before testing purity, you need to identify what’s actually in your sample.
Cocaine is frequently adulterated with dangerous cutting agents including fentanyl, levamisole, lidocaine, and synthetic cathinones. Testing your cocaine protects you from overdose, adverse reactions, and consuming substances you didn’t intend to take.
This guide covers three testing approaches: basic adulterant detection, comprehensive evaluation, and purity percentage testing.
How to Test Cocaine Purity Percentage
Most users want to know how pure their cocaine is. Our Cocaine QTest Kit measures the concentration of cocaine in your sample, showing you the exact percentage purity.
What Does Purity Mean?
Purity = concentration of active cocaine in your sample. Street cocaine typically ranges from 20-80% pure. The rest is cutting agents (some harmless like baking soda, others dangerous like levamisole or fentanyl).
Cocaine Purity Testing Kit
Our Cocaine QTest Kit detects cocaine concentration in powder or solid form. You’ll know:
- Exact purity percentage (e.g., “62% pure”)
- Total grams of actual cocaine in your sample
- Whether your cocaine has been heavily cut
⚠️ CRITICAL: Purity tests tell you cocaine concentration, but they do NOT identify cutting agents. You must first test with spot kits and fentanyl strips to rule out dangerous adulterants. A sample can be “80% pure cocaine” but still contain lethal fentanyl in the remaining 20%.
How to Test Cocaine for Adulterants (Reagent Testing)
Reagent test kits chemically identify what substances are present in your cocaine. Different reagents detect different cutting agents and adulterants.
Level 1 – Basic Testing (Minimum Protection)
If you can only afford one test, start here:
1. Fentanyl Test Strips (Absolute Must-Have)
Fentanyl-contaminated cocaine has caused thousands of overdose deaths. Our FentKit detects fentanyl and its analogs in seconds.
- Tests for 40+ fentanyl analogs
- Results in 5 minutes
- Single most important harm reduction tool
Why this matters: A dose of fentanyl the size of a few grains of salt can be lethal. Many cocaine users have no opioid tolerance and are at extreme risk.
2. Morris Reagent (Cocaine Identification)
The Morris Spot Test Kit is the only reagent that positively identifies cocaine. It also detects dangerous dissociative cutting agents:
- PCP, 3-MeO-PCP, 3-MeO-PCE
- 2-OXO-PCE, O-PCE, MXPr, MXE
- Other dissociative adulterants
Expected reaction: Pure cocaine turns the Morris reagent orange-red.
Level 2 – Comprehensive Testing (Recommended)
For accurate identification and detection of multiple cutting agents, we recommend our Cocaine Spot Kit Package. This bundle is cheaper than buying individually and includes:
Complete Cocaine Testing Package Includes:
✓ 10x Fentanyl Test Strips
Multiple tests to check different parts of your supply
✓ Morris Reagent
Positively identifies cocaine + detects PCP, dissociatives
✓ Marquis Reagent
Detects cathinones (bath salts), methamphetamine, amphetamine, 4F-aPVP, lidocaine
✓ Mecke Reagent
Detects cathinones, a-PVP, a-PHP, methylphenidate, additional stimulant adulterants
✓ Liebermann Reagent
Detects levamisole, ephedrine, amphetamine, cathinones, and other common cuts
Why multiple reagents? Cross-referencing results reveals hidden adulterants and gives you certainty about what’s in your cocaine. One reagent might miss something another catches.
What Are Common Cocaine Cutting Agents?
Understanding what your cocaine might be cut with helps you know what to test for:
| Cutting Agent | Detection Method |
|---|---|
| Fentanyl | Fentanyl test strips |
| Levamisole | Liebermann reagent |
| Lidocaine | Marquis reagent |
| Cathinones (Bath Salts) | Marquis, Mecke, Liebermann |
| PCP / Dissociatives | Morris reagent |
| Baking Soda / Inert Cuts | Purity test (reduces %) |
Level 3 – Highest Certainty Testing (Advanced)
Our Skylab Separation Test Kits physically separate mixed substances, allowing you to identify each component individually and estimate how much of each substance is present.
For cocaine testing, we recommend:
- Juno Separation Package – Includes Marquis, Mecke, Liebermann reagents for separation testing
- Add: Morris Spot Test Kit separately for cocaine identification
- OR get: Curiosity (Pro Level) Package – Includes ALL reagents plus separation equipment
Separation testing provides laboratory-grade insight into mixture composition without sending samples to a lab.
💡 Pro Tip: Separation kits are ideal if you’re testing larger quantities, want to know exact cutting agent ratios, or need the highest certainty short of lab analysis.

How to Test Cocaine: Step-by-Step Process
- Test for fentanyl first. Use Fentanyl Test Strips on a small sample. Wait 5 minutes for results.
- Identify cocaine with Morris reagent. Place tiny sample on white ceramic plate. Add 1-2 drops Morris reagent. Look for orange-red color change.
- Cross-reference with additional reagents. Test separate samples with Marquis, Mecke, and Liebermann to detect cutting agents.
- Test purity (optional). If all reagents confirm cocaine and no dangerous cuts, use QTest kit to determine concentration percentage.
- Document results. Compare colors to reaction charts. Take photos for records.
⚠️ Important Testing Notes
- Use tiny samples (few milligrams) for reagent tests
- Test in good lighting – color interpretation is critical
- Always cross-reference multiple reagents – one test isn’t enough
- If any test shows unexpected results, do not consume
- Store reagents in cool, dark place – they degrade over time
Cocaine Testing FAQs
How accurate are cocaine purity tests?
Our Cocaine QTest Kits provide accuracy within ±5% of laboratory results for cocaine concentration. However, they only measure cocaine content – they don’t identify specific cutting agents. Always test for adulterants first with reagent kits and fentanyl strips.
Can I test cocaine at home?
Yes. All our test kits are designed for home use and require no special equipment or training. Reagent tests take 1-2 minutes, fentanyl strips take 5 minutes, and purity tests take about 15 minutes.
What’s the difference between a spot test and a purity test?
Spot tests (reagent tests) identify what substances are present but don’t tell you concentration. Purity tests (QTests) measure cocaine concentration percentage but don’t identify cutting agents. You need both for complete information.
How much cocaine do I need to test?
Reagent tests require just a few milligrams (size of a match head). Fentanyl strips need about 10mg dissolved in water. Purity tests require 10-100mg depending on expected concentration.
Will testing destroy my cocaine?
Testing uses tiny samples – usually less than 0.1 grams total across all tests. The sample tested cannot be recovered, but the amount used is negligible compared to the safety benefit.
How do I know if levamisole is in my cocaine?
The Liebermann reagent in our Cocaine Spot Kit Package detects levamisole. Levamisole is an immunosuppressant veterinary dewormer commonly used to cut cocaine and can cause severe health problems including skin necrosis.
