Phentermine separation from methamphetamine

As a positional isomer, it shares a molecular weight and fragment pattern nearly indiscernible from methamphetamine by many LC-MS/MS methods. This assay showed good chromatographic separation of methamphetamine, amphetamine, and phentermine (Figure 1), permitting clear differentiation between these positional isomers.

Phentermine is an analog of methamphetamine. Similar to the amphetamines, phentermine increases the release of norepinephrine and dopamine from nerve terminals

Adderall does not contain methamphetamine. Phentermine (Adipex) is distinguished from amphetamine and methamphetamine during DRUGSCAN confirmation testing.

No. Phentermine (Adipex) is distinguished from amphetamine and methamphetamine during DRUGSCAN confirmation testing. Mass spectrometry provides a chemical fingerprint for phentermine, which is independent of those obtained for amphetamine and methamphetamine.

Does phentermine cause a positive result for amphetamines? No. Phentermine (Adipex) is distinguished from amphetamine and methamphetamine during DRUGSCAN
