im not an expert on this topic, but i think drug tests look for metabolites, i dont see how phenibut could show up unless they test for GABA or somthing

I asked it knowing some people would react as you did but really there is no need to laugh or at least keep it to yourself.
People would be shocked at what can cause a false drug test, things like seltzer water and asprin can cause false positives.

people have had a false positive for methamphetimine even though they did not use meth, ephedrine, amphetamines, or anything of the sort remotely close to meth and related stims. i understand your caution when it comes to drug tests, better safe then sorry. anyways i would think u are safe as GABA is natural in our bodies and phenabut is a derivative of GABA, as u probably already know.

take this for what it is worth:
(perhaps some more knowledgeable can translate this this if it is useful)
The principal mechanism of action of barbiturates is believed to be their affinity for the GABAA receptor(Acts on GABA : BDZ receptor cl- channel complex). GABA is the principal inhibitory neurotransmitter in the mammalian Central Nervous System (CNS). Barbiturates bind to the GABAA receptor at the alpha? or the beta? sub unit, which are binding sites distinct from GABA itself and also distinct from the benzodiazepine binding site. Like benzodiazepines, barbiturates potentiate the effect of GABA at this receptor. In addition to this GABA-ergic effect, barbiturates also block the AMPA receptor, a subtype of glutamate receptor. Glutamate is the principal excitatory neurotransmitter in the mammalian CNS. Taken together, the findings that barbiturates potentiate inhibitory GABAA receptors and inhibit excitatory AMPA receptors can explain the CNS-depressant effects of these agents.At higher concentration they inhibit the ca2+ dependent release of neurotransmittors

Took a NIDA 5 drug screen for new Employer a year ago. Was using plenty of Phenibut including the morning of the test.. passed with flying colors.
