GHB Drug Testing

Tested for in Standard Drug Tests? NO
Tested for in Extended Drug Tests? NO
Possible to test for? YES
Detection Period in Urine 12-24 hrs

General Information

The first thing to know about GHB and drug tests is that neither GHB nor its metabolites (the substances it is broken down into by the body) are tested for in the standard drug test. The basic drug test, currently used for nearly all testing programs (corporate, school, sports & judicial), checks for 5 types of substances

Cannabinoids (marijuana, hash)
Cocaine (cocaine, crack, benzoylecognine)
Amphetamines (amphetamines, methamphetamines, speed)
Opiates (heroin, opium, codeine, morphine)
Phencyclidine (PCP)


Detection Period

It is, however, technically possible to detect GHB with a drug test, but only for a very short period after use. Nearly all of the metabolites are gone from the body within the first 24 hours. Because they are so uncommon, these tests are much more expensive to give than the basic test. We have never heard of an individual being tested for GHB without a very specific reason to think they have it in their system, as would be the case with someone who believes they were given GHB by someone else (some date rape cases) and in some autopsy).

Field Tests

Some field test for GHB give false positives in the presence of soaps. One man, musician JM Giorsetti, was arrested and jailed after the police tested his Dr Bronner's brand soap and their GHB field test (NarcoPouch 928 GHB field test made by ODV Inc) showed a positive result. He was later released and charges dropped. See: Police Arrest and Jail Man After False Positive Test for GHB on his Dr Bronner's Soap, Apr 2007, NBC4.TV.

DR Bronner's soaps published a brief article and video describing the problem, in May 2007. They state the "NarcoPouch 928 field drug tests... will always give a false-positive for the drug GHB (Gamma Hydroxy Butyrate) if used on any true natural soap.".
