911Doctor :

Phenobarbital has a long half life

911Doctor :

depending on which reference you use it can be 3-6 days

911Doctor :

typically it takes 4-5 half lives for a drug to be eliminated from the body

911Doctor :

so that would be about 30 days at the outside

911Doctor :

this should mean you will test negative for barbituates on the test (phenobarb)

911Doctor :

so no, it will not show

911Doctor :

standing by
