Purity - cocaine HCl's reaction to vapourising / burning as a purity test

[vantranist]

SWIM wanted to test some coke he had picked up for meth witch he belived may have been used as a cut.

I know theres already well known tests and things to do this but SWIM tried another way to try and identify it, he thinks he was getting somewhere but didn't want to waste any more product especally if it wassent working anyways.


This is what swim thought may work and what he did:


SWIM took a few bumbs of coke, choped it ready for snorting and put it in a freebase pipe (meth pipe, glass pipe, crack, ect.) He then heated his cocaine as if it were tweak or crack, too see if the tweak cut would start melting and producing vapors, this was suppose to be the indicator of the presence of meth or not, however, because he has no idea how cocaine HCl should react when trying to vaporise it swim wassent able to tell if it was the coke or tweak.

What swim is asking more less is how should cocaine HCl react when trying to vaporise it? He asumed it would turn to black shit in the pipe, creating little if any smoke that would be very harsh and nasty. Instead what he saw was some of the coke powder turning to this black hard stuff, some Melting (could just be a cut) and a slight ammount smoke produced witch well may be the case if there was only a slight ammount of tweak in the coke, he found the smoke not to be too harsh either.

what do others make of this?

PS. the heat source was a normal bic lighter, and not held under the glass for too long at all... possibly seemed neat the time it took to melt and smoke crystal meth, but swim forgot too see how long it took exactly.

i dont think this forum will support the question about cutting agents in coke. sorry its just the rules.

I disagree, i feel this forum is all about harm reduction and getting th best possible product.

Possibly re-read my thread or mabye i wassent clear.

SWIM is trying to use a method to detect the presence of meth in his cocaine.

As far as meth goes, I -believe- it vaporises at a temp similar to that of crack. Also, as far as my experience goes, coke that melts and slowly turns brown when exposed to direct flame is good quality. Burning black or dark brown, especially less than 10 seconds, is a sign of inert cut. It should melt and bubble slowly, turning dark.

don't think observing cocaine HCl burn residues is a valuable way to evaluate purity...
way too many variables.

a heat based method does exist, measuring cocaine's melting point, which is quite high.

it is a method described in Gottlieb's "the pleasures of cocaine", and i think the "cocaine handbook", as shown in the movie "blow".
however it isn't that precise either and needs some decent setup.
and one would also need to have a chart with the different melting points of various inerts and actives etc...

just burning cocaine with a lighter in a glass pipe shows very little.

honestly, just forget about trying to identify cuts and go for the purifications methods described, such as the A/B or acetone washes.

this thread is ok for now, will just change the thread title.

Find a substance that cocaine WILL dissolve into but methamphetamine will not (or vice versa) and use that to extract. Despite popular opinion, the foily burning test for purity as well as the clorox bleach test are _useless_ at testing cocaine quality.

[beentheredonethatagain]

I think using A/B or acetone to clean the CCaine , will remove some cuts but if methamphetamine is was used as a cutting agent, would it still be in the final product? since A/B and tone are also used to clean methamphetamine?

[fidens]

acetone will NOT get rid of amphetamines however a full a/b conversion will. Honestly though there's very little chance that your coke is cut with an amphetamine. Doesn't make sense from a financial standpoint. If it's speedy it's (most likely) either unwashed cocaine alkaloids or caffeine, ephedrine, other shitty stimulant.

SWIM was thinking it was a cut made by a street deakeler. that maybe why.

[RashleySmashley]

SWIM wonders what makes SWIY believe the coke was cut with meth? It may be possible that SWIY has previously only had contact with oxidized coke or heavily cut unoxidized coke, and that this coke is of higher purity and unoxidized, therefore causing a different high. Or, has SWIY experienced meth before and detected glass in the coke that way?

Either way, SWIM does caution that she herself, as of late, has had contact with coke that was cut- heavily!- with meth on multiple occasions. Yeah, SWIM knows it sounds weird, but can assure you it is true. Def couldn't hurt for SWIY to do a little digging to see whats up...

SWIM thinks it may have meth because he heated it in a glass pipe and some started to melt after only a couple seconds, the smoke tasted sorta tweakish but cant be sure with that small ammount.

the high may last a bit too long after a good 2g+ session but who knows.

wait swiy is saying that swiy put rock into a tweek pipe and it tasted like tweek... swim dont mean to be rude but duh. pipes tend to get resinated with any smokes so of course it might taste tweeky. it would taste like weed if you smoked it on a resonated screen.

swim doesnt think there is really a good street way to determine quality other than doing mr le junk's wash.
