MDPV, breakdown temperature to gaseous state

Sorry, I am just a little sick of every MDPV smoker's opinion of how to smoke the HCl salt, when non of them match or make sense.

MDPV HCl (straight from internet package form, HCl salt, right?), has a vapor temp close to breakdown temp (where it yields other oxidizing reactions and unwanted chems).

Can anyone confirm the proper temp the HCl salt should not exceed to smoke?

I seem to be measuring somewhere in the 260-270F degree level that it melts down clear. But chemically I can't confirm that, visually I see a melt, but the smoke heavily yields at 300F+ temps, which also means the product turns dark and eventually black crisp. That has to be a no-no for the lungs.

I am going to convert to the base with Sodium Hydroxide for an actual "efficiently", "less harmful", smokable product, but until that point, what is the most proper temp and capture method for the HCl salt of PV to be inhaled?

Tolerance is high, I love MDPV, and if I must do it, I seek harm prevention! Thank you

You should not be smoking MDPV salts at all, like cocaine, they will just burn because oxidisation reactions prevail.

Even smoking freebase MDPV is not bright, it needs good temperature control to avoid deomposition.
 
I have some length of heat coil made for a lamination machine. you take the metal strip which is just thin flat wire inside to heat the long Al strip inside that does the laminating. Once the metal bowl (tin foil?) is made to hold the mdpv, it is wrapped with the heating coil on thrsexpository Ftt, the vapor bowl is ready to be made heated.

Using a quality power supply, IE. 0-30v, 0-3A, connect leads to heat coil at an initial low wattage (just do full voltage but start st low amperage.) Keep checking maximum temperature of MDPV contact point. This is a good time to buy a laser thermometer. Keep increasing amperage up maybe 0.15a if you are running 30v. Keep checking settled temp until you end at steady 260f. Add MDPV, see what happens. You want clear vaping salt that's not turning black! You may need more amps and 265, 270, 275 degrees etc.

The trick is keeping a chemical vaping, not oxydizing it.

It could work this way as salt? What do you think?
 
hcl smoked: instant hypertension headache, pounding in the ears

base smoked: near panic to find inviting hole into which probe can be repeatedly inserted & withdrawn

base variants: baking soda, ammonia, sodium hydroxide (ammonia is easiest for a quick and dirty conversion)

heated/not heated during conversion process

-> butterscotch, chalk, vomit pieces, maple sugar candy, hot buttered popcorn, etc.

Salts in general do not smoke well.

methamphetamine hcl? all i know is that smoking mdpv has been a big issue for a lot of people on this site. it may not be efficient but if say only 30% gets absorbed as a vapour thats still quite a hit you just need more of it and the high is meant to be insane.

mephedrone for one vapourises like methamphetamine but the vapour tastes horrible but it gave a huge euphoric headrush. nasty shit tho
 
^^Hahaha Sekio, that made me laugh.

Your posts reveal lack of vaping experience with pv, just so you know. Why comment on vaping when you haven't done it?

This is not meant as a dig...everyone knows your knowledge of chemistry is vast and that your intentions are good...
 
I have a sample of this stuff laying around, I may heat it in a melting temperature apparatus until it become brown-black and run a TLC on the pyrolysis products to see what comes up. Anyone have any suggestions for a solvent system?
 
cocaine is a substantially different molecule. methamphetamine is smoked as a sulfate or hydrochloride just fine. methcathinone too, if I recall correctly.
 
methcathinone, PCE, methamphetamine, amphetamine... are all primary or secondary amines and smoked as salts. Cocaine, PCP, nicotine, the opium alkaloids are tertiary amines and usually freebased.

I just think MDPV being a tert. amine should be freebased for best effect.

I've always been under the impression that sulfate salts cannot be vaporized because they will get charred before the vaporization temperature is reached.

This has also been my reasoning to why europeans never smoke their speed. (euro speed = amphetamine sulfate). Now I'm slightly confused.

Diamorphine is a tertiary amine and is smoked as a salt. I don't think it's nearly so simple.

Also, don't confuse common practice with only effective practice. There's little science behind why people are doing the things they do with drugs. They're doing what works, simply put. Nicotine is smoked as a freebase because that's how it's present in tobacco, not because a salt isn't smokeable (I don't know that it is, but whether it is or not has nothing at all to do with why it isn't smoked as a salt). Cocaine isn't particularly smokeable as a salt, so it isn't. I have no idea if or why PCP would be smoked as a freebase, but I assume it's because that's how it's supplied, not because people have found out through trial and error that smoking the salt of it just doesn't work.

most people will not smoke cocaine hydrochloride as its a waste of coke. the same behaviour does not occur with mdpv as people keep smoking it, which suggests it is effective depsite how hazardous it may appear.

also cocaine sulfate is smoked as paste in cigarettes

for example, unless i had smoked mephedrone for a laugh i would never have guessed it vapourises as well as it does (4methyl-methcathinone hydrochloride). mephedrone vapourised looks like videos of people smoking methamphetamine on the net that i have seen. also methylone will vapourise quite well also which i found out by accident after a delivery of poorly labelled goods :/
