Well, I'm no organic chemist, but I confused as to some of the confusion here and cited on the other forum, so I'm going to have to add my two bits to the various topics in this thread: First of all, there's a very very easy way to tell the difference between freebase DMT and the salt: the melting point. Freebase DMT has a melting point of 49-74°C (depending on the crystal structure), whereas the hydrochloride salt has a m.p. of around 170°C. So just put your sample in a shot glass in a hot water bath (not too hot, since if it is freebase it might literally go up in a puff of smoke (well, vapor)) . If it melts, it's freebase. I'm confused because this is like the whole idea behind the freebase vs. salt issue. The freebase form of a drug will melt and vaporize at a low temperature so can be "smoked" (actually vaporized) easily. This is why people convert cocaine-hcl or cocaine-sulfate into crack, but [i:41d1772df7]everybody[/i:41d1772df7] knows that, right? The salt has a much higher melting point and hence will usually combust before vaporizing, destroying the drug. On the other hand, hcl salts of drugs (including pharamceuticals) are important because they're water soluble (the freebases aren't), so can be injected or insufflated. I'm not a doctor either, but I highly recommend against insufflating or injecting the freebase, and I don't care what that dude at peyote.com says... EDIT: however, see comment on Ott's insufflation of freebase bufotenine three posts down... The next reason why I'm confused is because of the questions regarding converting freebase<->hcl salt. As far as I know (and please correct me if I'm wrong), the whole [i:41d1772df7]point[/i:41d1772df7] in the A/B extraction teks is to use these conversions to extract the alkaloid. You add acid to convert the freebase in the plant material to the water-soluble salt so it dissolves into your solution. Then you basify to convert back to the water-insoluble freebase (which presumably precipitates out). The freebase is soluble in non-polar solvents, so you mix with a non-polar solvent to pull out the freebase. In mhrb, the DMT already exists as the salt in the bark, which is why Noman can skip the acidification in his wonderful "dmt for the masses" tek. As far as I know (again correct me if I'm wrong or oversimplifying so greatly as to be essentially wrong, especially in light of what Master Chemist Shulgin says. see below.), you can convert any alkaloid to the salt by acidifying with HCL acid and evaporating. You can convert any HCL alkaloid salt to the freebase by adding a strong base and evaporating. This is exactly how they make crack. Read this nice summary from the CIA. The first section is "Production of Cocaine Hydrochloride" and the second is "Production of Cocaine Base (Freebase and Crack Cocaine)":
CIA-Contra-Crack Cocaine Controversy also read this Erowid answer on the difference between freebase and salts for drugs in general:
Ask Erowid : ID 2348 : What does it mean for a drug to be a "freebase"? How does one make a freebase? On the other hand, the one point that really indicates this is an oversimplification is that Shulgin reports in Tihkal (see reference at the bottom) a rather complicated recipe for producing the HCL salt of DMT and says, "this[...]is the only claim of a valid hydrochloride salt of DMT" and "I have personally had no success [with this recipe] at all", indicating to me that it's not quite as simple as my limited knowledge of chemistry would lead me to believe. The recipe cited by Shulgin uses diethyl ether saturated with anhydrous hydrogen chloride just as Noman mentioned above instead of muriatic acid. [b:41d1772df7]Noman[/b:41d1772df7]: why does one need anhydrous hydrogen chloride instead of muriatic acid? [quote:41d1772df7="Doerak"] This is just speculation, but isn't the following possible: DMT freebase is soluble in non-polar solvents. DMT HCl is soluble in polar solvents. [/quote:41d1772df7] yes, this is the point... [quote:41d1772df7="Doerak"] Add ultrapure crystal to (almost) pure alcohol (polar solvent). Add tiny bits of HCl until the DMT falls out. This should happen at exactly pH=7. It's probably impossible to get all the DMT out as crystals so freeze precip the alcohol and see what happens.[/quote:41d1772df7] again I'm confused. By your very statement, if you add freebase to alcohol it won't be soluble in it. and if you add HCL converting the DMT to a salt, it should become [b:41d1772df7]soluble[/b:41d1772df7] in the alcohol, dissolving into it, and not precipitate!!! Or what exactly do you mean by "fall out"? Regarding IV dosing of DMT-HCL: [quote:41d1772df7="DMTripper"][quote:41d1772df7="orangetonic"] Thanks for the dosing information. I'm 6'4 220 lbs, so that would be about 20mg DMT HCl, if I go on the higher side. Is that I.V. ? [/quote:41d1772df7] I think that's around 40mg but I'm not too familiar with pounds so I'm not sure. And yes thats IV. [/quote:41d1772df7] Strassman reports 0.2mg DMT-HCL per kg bodyweight for threshold psychoactive low dose and used 0.4mg/kg as a high dose. While determining the high dose he administered up to 0.6mg/kg to some experienced users and they found it to be too much. For the 220 lb example above this would mean (2.2 lbs=1kg -> 220 lbs = 100kg, 100kg*0.2mg/kg = 20mg, 100kg*0.4mg/kg = 40mg) 20mg for threshold dose, 40mg for high, and 60mg for a most likely too high dose....hope SWIY has an analytical balance.
Doses of DMT for Intramuscular (IM) administration are approximately 1mg/kg. [quote:41d1772df7="orangetonic"]Actually one of my friends referred to this as "research Strassman-style" but I don't have a copy of his premiere DMT tome.[/quote:41d1772df7] Let's keep this quiet, but Strassman's book is available as an online reference for anybody who bothers to have a look around the nexus. Strassman's Text is requisite reading if you ask me. It's in our interest for books like this to be sold and disseminated. Use the electronic version just as a quick reference and buy the book. [quote:41d1772df7="Doerak"][quote:41d1772df7="DMTripper"]You can change freebase to salts but it's more complicated. I read someting about it once but it was written by some chemist for chemists so I didn't really understand a word
[/quote:41d1772df7] Do you mind posting this tek if you can find it? I have some chemistry knowledge, so I might be able to understand it.[/quote:41d1772df7] Doerak: see Tihkal #6:
