Stimulants Is it possible to smoke racemic methamphetamine?

[dwak]

Hello,
Is it possible to smoke racemic methamphetamine phosphate with glass pipe as "ice" meth commonly smoked?

Thanks

yes

What an odd choice of counterion! sekio, could you shed light? Is it the case that there's a synthetic route that naturally results in it, a la 2C-B HBr?

Hi guys, thanks for your attention. Could you please explain it in more detail?

I'm not deep into chemistry. Am I wrong thinking methamphetamine phosphate is a sault? If it's sault, will it vaporize in such conditions as "ice" meth does? I've read saults are much different in that context.

As I understand, racemic meth is mix of d- and l- , though l- has less recreational effect. Does it mean dosage is about two times larger than with "ice"? What will become with l- dominant when it vapourizes? Will it vaporize too?

P.S. Sorry if my english is broken a bit, that's not my native language.

Cheers

"Ice" meth is also a salt, d-methamphetamine hydrochloride. Yes, the dose is about half that of racemic meth. l-meth has mostly peripheral sympathomimetic effects.

Meth phsophate is a salt, but "ice" is also a salt - methamphetamine hydrochloride. Methamphetamine freebase is an oily liquid. It should be possible to smoke them both; the acid will dissociate from the freebase meth in either case.

Yes, the l-meth vaporises too, it's simply a mirror image of the d-meth molecule. In general dosage must be increased by around 50 to 100% if you go from d-meth to racemic.

The counterion in meth production doesn't, in general, come from a specific part of the synthesis, it just comes from whatever acid you use to form the salt. You can make meth citrate or whatever if you wanted to. (In fact, people resolve d- and L-meth by crystallising a (+ or -)-tartaric acid salt)

sekio, thanks for the detailed answer. I could not find an answer on web for a week, really.

One another thing, if it's phosphate, is it safe for lungs to smoke it? I mean, isn't it more harmful for lungs than smoking hydrochloride? If we talk about rather clean product without cut contaminations. I mean, maybe process of making meth phosphate includes some materials which are hard to clean out, and which are harmful for lungs?

Yeah, that's what I thought, I just wondered if you could speculate with regards to the choice of phosphoric acid to salt out the amine. Perhaps to add weight?

dwak, the process of making meth phosphate vs. meth hydrochloride just depends on which acid the chemist chooses to use to convert the freebase into a crystalline salt, it's not even really a step of the synthesis, don't worry.

I think it's just based on whatever the cooks have on hand. Maybe it has to do with deliquescence (e.g. meth HCl will form puddles in damp air, but maybe the phosphate won't?) Maybe the cook didn't want to use a HCl gas generator.
