Does Concentrated Bath Salt Show up on a Drug Test?

They can

Test for a thing it's what they re going to pay for to be tested that is. Special test that cost money.

i get drug tested every month. i do, however, know when i get tested. but here is the deal...i did some of the kush blitz bath salts(and no...i dont feel like killing anyone or cutting myself, or anything stupid like that)last night. my drug test is tomorrow but even if it does give a false-positive result, you have nothing to worry about as in most states(not sure which state you are in)there is no illegal chemical properties in this. So if you are in one of the many states where mephedrone has not been deemed as illegal, then does it really matter? if you know that this is all you have in your system you can just tell your doctor/P.O./etc. that you took an over the counter upper like NoDoze, or you can tell them you were feeling sick and took NyQuil, Vicks Inhaler, etc. If you are getting a hair/blood analysis/GC-MS urine drug tests...the results will come up negative unless if they are actually LOOKING for mephedrone so you will be fine. If immunoassay urine tests(most common) are used...that would be the only type that might possibly show up as a false-positive, which means they will send it off and it will come back as negative for illegal drugs. Dont worry about it at all dude. I dont even think any of the compounds in there will show as amphetamine. Even though, yes i know, it is very close...i have researched this for about 7 hours and have yet to read about someone failing cause of these. The only people that said you will fail are saying this from the 3rd person. The people that said they would show up negative actually took the tests and passed themselves. So dont worry about it...just be careful as to how much you do. im ADHD and am prescribed to adderal but i prefer this most of the time because it has the same feeling(might be different for me because i have tolerance to amphetamine and am actually supposed to be taking it)and its cheaper. hope this helps...at least ease your mind a little if anything. i will repost tomorrow after i get my drug test and let everyone know the results so there will actually be some legit replies to this question rather than guesses.
