Help Cocaine Morris A/B reagent

[cgdon]

Hello, I bought some cocaine, but I don't feel much of it. I only have the Morris A/B Reagent kit left. This one is this blue.
Does this mean it's cocaine?

A limitation of all of the presumptive tests is that they will tend to attract a certain type of researcher into finding a cut that will fool the test. In this case I've read that dimethocaine will do just that. I cannot confirm the veracity of the claim but it's one worse because it's a semi-active cut. Also, I suggest that homologues of dimethocaine and possibly clofenciclan would also fool it.

I don't think anyone can provide assurance based on the limited information but at least it's possible to flag potential issues. DRIs are deeply dysphoric for me so I feely admit to not being that well informed on the subject. Others likely know far more than I.

^ I dooubt it with be dimethocaine as reports indicate like 5 minute bell ringers when IV'd -- suggesting it may be worth more on the blackmarket, or be more desireable (Perhaps not). 3x toxicity 1/3 potency - total shite snorted.

Am I incorrect in saying if there is any cocaine it would turn blue?

Would you be better off with the old (shit I forget im old )-- bleach swirl method?

@notsmokeymcpot42088 - I think that may be an issue with the test. It's qualitative rather than quantitative.

I really should learn more about cocaine as Europe is currently a market that's expanding really quickly. In 2024 a total of 323 tonnes of cocaine was seized. In 2025 it was 419 tonnes. But that figure is just a snapshot. In the last decades it's increased from what had been a reasonably steady 50 tonnes per annum for some years.

The level of violence is something we hadn't experenced until the flood of coke. Bosses walking around with tooled up bodyguards being shot dead in broad daylight on busy streets. It does seem that the methods used by the cocaine cartels have been exported along with the product.

Maybe it turns a darker blue the better it is or something idk? I know cops use the same reagent test roadside and if there is any cocaine -- or other product that will flag it. (I guess idk the ng/ml but it must be uber low as ppl try puttin grams in water bottles than get charges for 20 oz's (which is wild in itself and so unfair!).

Sorry undiagnosed ADHD -- the point is it turns blue no matter how little coke is in the coke as long as it is ANY

Id look up the old bleach swirl method -- idk even know if its bleach I forget but you drop it in something and by the way it falls you can roughly guage purity. (Think it may be seen in the movie blow along with other purity testing methods that are less available?)

I don't KNOW but I'm guessing that bleach being sodium hypochlorite (NaOCl) i.e. NaOH and Cl2 dissolved in water might mean that it freebases alkaloids and specifically in the case of cocaine it hydrolizes the drug and finally chlorinates the tropanes.

So those ring-chorinated compounds absorb specific frequencies of light which would result in a colour change.

But I emphesise that this is purely a hypothesis and if others more knowledgable know better, I would appreciate the correct answer. I have always said that for me, BL offers a place for others to read the same papers as I provide, add others if I've missed some and between us, WE arrive at the correct answer.

Shoot I came across two articles with paywalls so here is the brief google A.I

The bleach test is a simple, visual, and harm-reduction method used to estimate the presence of cocaine by observing its reaction to sodium hypochlorite (common household bleach). However, it is important to understand that this method is highly unreliable, scientifically invalid, and cannot accurately determine purity or detect common dangerous adulterants like levamisole

1. Prepare the Sample: Place a small amount of household bleach in a clear container (e.g., a glass dish or, preferably, a clear shot glass).
2. Add Sample: Drop a small amount of the powdered or rock substance into the bleach.
3. Observe Reaction:
   • Pure/High-Quality Cocaine: Generally, pure cocaine dissolves instantly, leaving no residue. It often produces a "fluffy, white precipitate" immediately upon contact.
   • Impure/Cut Cocaine: Most impurities, adulterants, or cutting agents (such as talc, starch, or certain medications) will either sink to the bottom, fail to dissolve, or cause the bleach to turn different colors (e.g., orange, red, or dark brown).

This doesn't sound right to me -- perhaps it wasn't bleach but alot came up on google just nothing very useful

Indeed in a normal reagent test the darker the blue the 'purer' the product -- unless other caine products (but 4d would know more bout that than me)

You can always use temperature melting point if you wanna go wild?

I would expect a darker blue up to a certain point. But once there is enough of the cobalt complex to absorb 100% of the blue light (550–630 nm), it won't get any bluer.

But I'm almost certain that if dimethocaine homologues and/or clofenciclan do actually produce a blue complex, it won't be at the same wavelengths. But if used as a cut, would the mixture be a significantly different blue? I can't answer that.

Even decades ago there were a couple of Dutch vendors offering test-kits that provided qualitative data i.e. showed how pure a sample was. I really have no idea if they work. But I guess the fact that they HAVE been around for decades may suggest they must have some value.

Did a bit of searching for the test you been talking about. Never used one myself.
Found online sites selling EZ test Cocaine/ Crack 3 total, maybe 4. The brand sell s several other s for about any drug that s available. Can i add a link to them ? Let me know if allowed.

Not a expert by all means there seem to be 3 test s. I assume the procedure below is a combo. if step 1 would be detecting the substance itself the other 2 for purity and a few cuts but not all.

It s a 3 step procedure
1 Scott-reagens/ 2% CobaltThiocyanaat in glycerine, water
2 HydroChloric-Acid a.k.a. Muriatic-Acid to acidify
3 Chloroform

Along with a color code to interpret the result s. Can t find it on their website
Warn s that the Scott reagent also react s with MDPV and 5-Meo-MIPT To detect cut s like Levimasole, Phenacetin and Ephedrine. No mention of -caine s/ Clofenciclan.

EZ test Australia has a color chart for purity, it s deep red/ high to orange/ low content
Dancesafe has one that uses: Morris, Marquis, and Liebermann reagents. And a lot of info that might interest Cocaine user s.

BTW before crack, apparently freebasing of cocaine was used to test purity - before people caught on to cuts that would get aroud that simple test.

But quite often those large-scale importers would employ a human guinea pig, usually someone in debt and/or slave to the drug. They would then smoke said freebase and report on the effects. I understand the practice began in the 1960s and I highly doubt even a young guinea pig would be alive to provide further details.

When MDMA appeared a story was related to me of someone who for a couple of bags of brown, would BE that guinea pig. He swallowed a cap; nothing. He snorted a cap; still nothing. Finally the seller who was confident the powder was good mentioned that it was pure enough to vape. So said guinea pig was mid-vape as the first two doses kicked in. Their subjective reasoning was that methadone had some how slowed down the action, but in truth, I think it's because fof them, a GOOD pill is felt in ten minutes (they were a big Palfium/Diconal fan).

Anyway - they dropped dead one day.

that was one hell of a punchline
