Yes benztropine causes false positives
No it can not.
To the best of my knowledge, energy drinks cannot cause false positives for PCP.
Dextromethorphan Or robitussin has been known to create false positives for opium and PCP.
Are you asking about the sleeping pill ambien? No, it will not test positive for anything.

Could be one of the medications (like insulin) that they take, or just the disease internally itself. Its possible as kidney disease/infection can cause a false positive for amphetamines.The 1st post under the OP by sublime1-ga has a list of chemicals and things known to give false positives (thc and amphetamines included)
can dilaudid cause false positives withgabapintin klor-con furosemide cyclobenzaprine morphine simvastatin baclofen lisinopril vitamen b-12
No, psilocybin/psilocin and PCP are very different chemicals and will not cause false positives for one another.
I've been googling and found no relation between those two for causing false positives for PCP, I've seen dextromethorphan or certain SSRIs like Cymbalta ad Effexor cause false positives and if you failed and took any of those than that may be the cause.
