yes it can
No, taking coumadin and phenergan will not test positive for pot.
Phenergan is a drug used as a antihistamine and to treat allergies. Parkinson's is not a side effect of this drug, but if you are taking any medications for Parkinson's, you should tell your doctor.
If they are barbiturate based then they will.
If phenergan is the ONLY medication/drug taken, (and no drugs of potential abuse have been ingested) then you will pass a drug test.
Ativan does not normally show up on a drug screen as a barbiturate but rather as a benzodiazapine.
No
I am not a doctor but I do have experience with UA's and promethazine or as it is commonly referred to as Phenergan has nothing in common with cocaine so in my opinion it is very unlikely for Phenergan to give a false positive for cocaine. It is much more likely if you did come up with a false positive that the test is simply bad and wrong This has happened to me.
No, it is related to substituted pyrimidine derivative which has similar action to that of Barbiturate but doesn't belong to barbiturate, phenyton related to group of Hydantoins.
no, but the codeine will.
what medications cause a false positive on a drug screen for marijuana?
No. It is an artificial drug made with MDMA.
It is a temporary state of unconsciousness brought on by a controlled dose of a barbiturate drug, usually pentobarbital or thiopental
