Does amphetamines cause positive urinalysis

The answer is YES. I have never used amphetamines in my life. I recently began using a workout product that contains 20mg of synephrine per capsule. I never take more than two capsules per day. A few days after my last UA, my parole officer called me up and said that I tested positive for amphetamines (which I told her was IMPOSSIBLE). I then went through every single thing I put into my system (all legal mind you) and after some intense internet research found that synephrine was originally created as a synthetic amphetamine and can most definitely create a false-positive for amphetamines on a urine analysis.
