Cocaine Purity

What is an efficient way to test the purity of cocaine?

 

use a hot plate........ if it is good stff it should not burn at less than170-180 degrees farenheit

 

Ok I know that from BLOW but is that a real accurate way to test? I was going to use that method but I wasn't sure if it was legit. Cinema and drugs can so often lead to mis-information. I mean look at Fear and Loathing... Truely didnt capture the essence of being strung out (But was bad ass as all of hell)

 

yep, the melting point test.

we use that test in chemistry all the time; it's the first test you perform, even before GC/IR/Mass Spec, etc.

pure cocaine muriate (hcl) actually melts @ ~ 195 deg. C (from Merck 12th Ed)

impure coke will melt much lower than that.

 

I don't wanna get too off topic, but I don't follow what you're saying about F&L, seems pretty accurate in that respect. Wnat makes you say that?

 

^ Yea the only part that comes to my mind as being overplayed, was the adrenocrome scene, which they said they did. Other than that it's accurate

 

Not an overplayed... Underplayed. Crashing on the mescaline... The flamingo hotel.... It didn't feel right. The ups were good, but the crashes were just kinda weak... However when Dr Gonzo was strung out on LSD it was pretty good

 

Um...you do realize that the movie was made from a book which was a true story? Read the book and maybe you'll find out some other things that you couldn't from watching the movie. Hunter S. Thompson was known for having an exceptionally vivid memory, and he's a journalist by profression (well, was). That's where the term "gonzo" journalism came from anyway - write down the sequence of events AS they happen.

Sometimes movies are accurate.

 

-sigh- Ok... Im usually calm but FUCK YOU! How dare you insult my fucking intelligence. Thompson was also known as a burnt out wasteoid. That is fact. Now if you want to try and educate someone on his book, try a 15 year old. Im saying that the way the movie PORTRAYED those crashes didn't seem to true to the book. And you can go off talking about all how he was on board with the project all you want. Sometimes people do movies for the money

 

^^^Hey man, chill, you don't even know each other so what's the point of getting all bent out of shape about it?

Anyway, concerning F&L, having read the book and seen the movie, I thought the movie was very accurate *to the book*. Not saying accurate to what the feelings "should" be or whatever, but from book to movie was good.

 

Umm... lick it and see if your tongue gets numb. Always worked for me. lol

 

I've known enough people to know that when you open up with a sentance like that its not because you think the person is educated. I personally feel that from book to movie the lows we're underplayed. Thats just me. Now my decision in that plays off of my own personal experiences with drugs and how I read the book and understood it. I don't enjoy people talking down to me... I take it personally as it is a personal insult to my intelligence... I'm not trying to start a flame war, I'm just saying in plain english what was said to me in an extended language... But this needs to be in a different topic.

Any other methods for testing cocaine purity?

 

I was hoping for something more accurate. A cut that I know people use called Bolivian (sp?) Flame creates the same kinda numb

 

wow lol.. craaaazy man, i see it from both perspectives though, but methinks someone's ego needs a downsize effort, defending your 'intelligence' so quickly and dilligently. It's a reasonable assumption that most people who have seen the movie have never read the book, sooo just chill out man. Not even going to get further into the topic of the book though cause that's not the issue of the thread, I shouldn't have asked....


As for testing, the hot plate is your best bet I'd say. You can usually tell by the taste how garbage it is... but then again the raw is still garbage IMO. It's a pig drug.

 

agreed.

F&L quarrelling aside (ok movie, better book), m.p. test is the most practical test for purity. It's the very first procedure you learn in college o. chem.

and yeah, coke is a bullshit drug which strokes the ego to the point of grandiosity.

 

Well yeah... Its terrible... But that doesnt mean I should settle for terrible crap As for the getting fiesty.... Yeah I was drunk... BUT! I still didnt like the matter-of-fact attitude ... I didnt spend 5 years in high school for nothing =P So Im good between say... 140+ Farenheit? Poly put C but that has got to be a typo... I know freebasin doesnt need THAT much heat =P

 

oh no, that's correct; I quoted it straight from the Merck, all temps are in Celsius. cocaine hcl m.p. ~ 195 deg. C

the hcl salt of an alkaloid is an ionic compound, and will always melt at a higher temp than the free base (which has weaker intramolecular forces).

when you get the cocaine in powder form, that's the hcl salt; you have to heat it in dilute NaHCO3 to convert it to the free base.

 

Whoa whoa... 195 degrees celcius? Damn... ok... O_O thats fuckin hot

 

sort of

NaCl (table salt), is an ionic compound too (an HCl salt). it's m.p. is 804 deg. C

 

How can you find out the ratio of cocaine? we know that the m.p. is 195°C for 100% pure coke but how pure is for example 180°C??
