Just curious if anyone here has ever taken a drug test while on phentermine? Did the test come back positive for amphetamines? Did you have to take a secondary test?

There is a lot of anecdotal stories out there, but I'm curious if any forum members have any experience with this.

It very much would:
"Phentermine is a substituted amphetamine which has a methyl group on amphetamine 's alpha carbon. It is a positional isomer of methamphetamine and other methylamphetamines. The molecular formula of phentermine is C 10 H 15 N."

I had access to it once, friends wife was "losing weight" so they had them. It was very strong stuff, I picked pecans that day, was insane how strong it was. Almost too much so.
