Bath salts (bk-MDMA, 4-MMC, MDPV...) give positive results in anti-drug tests for substances such as MDMA, amphetamine...?

[antrax]

I have doubts as to whether bath salts (bk-MDMA, 4-MMC, MDPV...) give positive results in the reactive anti-drug tests used to detect MDMA, Amphetamine...) or not...
Thank you all!!

I don't think MDPV has any metabolite in common with MDMA; so no.
It's a Pyro and more smilar to Alpha-PVP than MDMA, even the chemical structure likes like a combination of both.

The geeky answer is that ketone containing stimulants are metabolised to their hydroxy analog that is also produced when similar substances without ketone moiety are consumed. Thus they all have metabolites in common but it is not known to me wether their half-life has anything in common. I have come up with a mouth spray that invalidates most saliva tests (do not let the metabolite interact with the antibody contained in the test). If positive to meth you should declare abuse of ephedrinated nasal spray as a cause for the false positive.

HerrHaberthe nasal spray abuse declaration got my mate's truck driver licence back since he is a professional driver... and we ravers depend on truck drivers as we depend on people like me teaching chemistry around.
