With a prescription for adderall (amphetamine salts) will a positive result for this look the same as a positive for Molly (MDMA) or will the two different amphetamines be tested differently and told apart on a hair follicle drug test? Also is two consecutive night uses of Molly enough to show up in a hair follicle test where doses were small and ingested by mouth?

Just 2 doses of anything will not show up on a Hair Test. Yes, there are tests to differentiate between Molly and Adderall.

Ok. So I shouldn't be worried that the Molly is in detectable amounts?

Correct, if 2 doses is all that you took in the last 90 days, you will be clean.

As for the Adderall, does the people who're requiring this test, being your employer or parole board, know about the prescription? If they don't it could cause some grief.

Adderall won't show up in a hair drug test because of the initial screening process the hair goes through but could show up if the sample is sent straight to the GC/MS confirmation process. The only reason to send a sample straight to GC/MS confirmation would be if they didn't have much hair to do both the screening and confirmation testing. That doesn't happen very much. This year I probably have only done a few "straight to confirmation" hair drug tests. Hope that makes some sense! Anyway Molly is not exactly the same as MDMA. Here is what I have on my web site in regards to "Molly".

The term "molly" is short for "molecule" and refers to MDMA in powder or crystalline form which usually implies the purest form of the drug. Molly, more accurately is TFMPP which stands for 3-Trifluoromethylphenylpiperazine which is a drug of the piperazine biochemical category that equally combines with its analogue benzylpiperazine (BZP) which is also sold as a lawful alternative to the illegal drug MDMA ('Ecstasy').

If it is truly Molly is won't show up in a hair drug test. Keep in mind street drugs can be and usually are cut with other substance so you really never know what you are getting so there is a lot of risk involved. Is it worth it??
