    sorry if this has been disscused already swim searchd but could'nt find anything.

    If MDPV is being used on regular basis will it show a positive or false positive on drugs test for Amphetamine, MDMA or Riltalin/cocaine?

    MDPV is unlikely to cause a false positive on the instant tests because of the beta-ketone and the amine group is in the form of a Pyrrolidine ring.

    Even if it does dispute the test and tell them you want a a confimation test done. The confirmation test would definitely come back clear.

    Yes you could test for it as you can for almost every chemical known to man. However the likelyhood of them doing a GC/MS test looking for a rather obscure substance like MDPV is almost zero.

    If you are on probation and got caught in possesion and using it, then maybe they may test for it, but the drug test results wouldn't really be necessary in that case since you got caught red handed.

    I would also like to know if any more of You has had personal experiance or knows first-hand if MDPV causes false positives on (any kind of) drug tests (and which kind?)

    Any information would help SWIM greatly.

    Yes. "Amphetamine" in a standard hospital urine tox screen. Apparently borderline, but on multiple occasions.

    A zebrafish went to the hospital in June spurred by an MDPV-induced panic attack, stupid fish. Recently zebrafish managed to get their records from that hospital visit (it's a long story). Sure enough, they did a drug test, with the following results:

    Cocaine: Negative
    Barbiturates: Negative
    Amphetamines: Negative
    Tetrahydrocannabinol: Negative
    Benzodiazepines: Negative

    That was the standard 5-drug test; there's also a 10-drug test that includes MDMA, which I can't speak for. I'm kind of surprised they didn't do the 10-drug test honestly, and I wish I had more information, but MDPV definitely does not cause a false positive for amphetamines.

    Joe Smith recently started a drug diversion program for possession of marijuana and thought that since they were still selling MDPV in stores it would bypass the system. Joe Smith tested positive for Amphetamines with the EMIT test but since he didnt dispute the claim it wasnt sent for the GCMS confirmation.

    Also he had heard about the baking soda for Methamphetamine theory, as well as tried the Aspirin, Niacin, Vinegar and lots and lots of water. He just tested tonight so Ill will update with the results.

    Well this girl in truck driving school officially passed her DOT drug test! They weren't even suspicious about ANYTHING in her system! THIS IS A HUGE POSITIVE INPACT ON HER LIFE! Be careful though everyone. Drug testing and requirements can change with out notice and any time!

    MDPV can turn the immunoassay positive at very high concentrations. Some hospitals still use chromatography which appears more sensitive than immunoassay. Please note there is no published data to the end above but it is possible.

    MDPV is possible to test for, but not on a standard 5-panel urine test. I have never experienced a false positive for PCP, nor MDMA, and amphetamine is positive for medication. It seems that MDPV is reliably undetectable. Literally, one could be shooting up all day and as they piss they will still be clean. Just passed a test the other night, nothing unusual. This was a few days after a bit of MDMA was consumed so that was also negative.

    Prince Myshkin was recently subjected to a 12 panel. 5 hours prior he had consumed mephedrone and mdpv. He tested positive for amphetamines and had not used amphetamines whatsoever for months. Myshkin just hopes that the GC/MS confirms the lack of amphetamine and doesn't report the mdpv and mephedrone.

    are you 100% sure these products you consumed were in fact mdpv and mephedrone??. I have had experience with drug testing while using MDPV and never once came up positive for amphetamines. Not 100% sure about mephedrone though

    Yeah, oddly enough Myshkin possesses the full dance safe screening kit and mdpv was positive. Although he could've tested the mephedrone with the kit he didn't. He's relatively confident it was mephedrone, but who knows these days? If he had to guess the culprit he would say it was the mdpv, which he knows is odd because others like yourself have first hand experience with it not causing a false positive. The reason he doubts mephedrone is the culprit is because the week before he had ingested mephedrone and came up clean. The only variable added to the equation for the false positive was the mdpv. Perhaps it was due to large concentration of mdpv or the type of test.

    personally i would suspect the Mephedrone because its chemical structure is more similar to amphetamines than MDPV is. And the only thing i have ever heard/read about MDPV showing positive for on drug test was PCP and even that was questionable. I can quite confidently say the pure MDPV does not show up on regular piss tests from all of my previous experience, which is quite extensive

    well, Myshkin has another test tomorrow. Been 4 days since suspected mephedrone was used and only 1 day since MDPV. Actually feels quite confident that he'll pass tomorrow and believe me, I hope you are proved correct on this one Dr. Ace. Results to follow

    Everything came back negative, having ingested MDPV 24 hours before.
