Cocaine's Three Separate Questions
No single test answers everything about a bag of powder, because there are three independent questions:
- Is it cocaine at all? (identification)
- What else is in it? (adulterants — the levamisole question)
- How much of it is cocaine? (purity)
The kits below map one-to-one onto those questions, which is why serious testers own more than one.
Best Value: Cocaine Purity Kit — $10.00
The Cocaine Purity Kit gives a semi-quantitative estimate of actual cocaine content. Typical street cocaine runs 40-70% — the rest is cuts — and knowing which end of that range you are on directly changes dosing risk.
Pros: cheapest meaningful cocaine test; answers the question users actually care about; simple visual comparison scale.
Cons: assumes the sample IS cocaine — run identification first on unknown sources; resolution is a range, not a percentage.
Best for Identification: Cocaine & Crack ID Kit — $25.00
The Cocaine & Crack Identification Kit answers question one with a clear chemical reaction for both powder and rock. This matters most with a new source — total substitution (benzocaine bricks pressed to look like the real thing) is a known scam because numbing agents fake the gum test.
Pros: works on powder and crack; catches the total-fake scenario the purity kit misses; 50+ tests.
Cons: identity only — says nothing about levamisole or purity.
Best for Adulterants: Cocaine Cuts Kit — $20.00
The Cocaine Cuts Kit screens for the cutting agents that cause real harm — above all levamisole, a livestock dewormer found in a large share of world supply, linked to agranulocytosis (immune collapse) and skin necrosis in chronic users. It also flags common local anesthetic cuts (benzocaine, lidocaine) that mimic cocaine's numbing effect.
Pros: targets the single most harmful common adulterant; exposes the numbing-agent scam; complements the purity kit perfectly.
Cons: cannot quantify how much levamisole is present — any positive is a strong signal to discard.
Non-Negotiable: Fentanyl Strips — $4.40
Fentanyl-contaminated stimulants kill people who have zero opioid tolerance — these are the deaths where nobody saw it coming. Dilute at 10 mg/mL (the stimulant ratio — more dilute than the opioid protocol, to avoid false positives) and run a strip on every new batch. The strips vs reagents guide covers the details.
The Full Workup, In Order
- New source? → ID kit first: is it cocaine?
- Every batch → fentanyl strip at 10 mg/mL
- Known source → cuts kit: levamisole screen
- Dosing decisions → purity kit: how strong is this actually?
All four together cost $59.40 — and steps 2-4 take about five minutes per batch once you have done them twice.
Frequently Asked Questions
What is levamisole and why is it in cocaine?
A veterinary deworming agent added at the production level because it potentiates and mimics cocaine's effects while surviving common purity checks. Chronic exposure is linked to agranulocytosis (a dangerous white blood cell collapse) and skin necrosis. It is the main reason a cuts screen exists.
Does numbing prove cocaine is real or strong?
No — the gum-numbing test is the most exploited folk test in the market. Benzocaine and lidocaine numb identically and cost pennies, which is exactly why they are the standard cut. Only a chemical test answers the question.
Why is the fentanyl strip dilution different for cocaine?
High concentrations of stimulants can cross-react with the strip antibodies and cause false positives. Diluting to 10 mg per mL of water (versus 1 mg/mL for opioids) removes that interference while staying far above the strip's fentanyl detection threshold.
Can I test crack with these kits?
The Cocaine & Crack ID kit explicitly supports rock form. For the cuts and purity kits, crush a small fragment to powder first — results read the same way.
