None of this is making any sense to me at all. A standard 12-panel drug urine screen (UDS) checks for cocaine, cannabis, PCP, amphetamines, opiates, benzodiazepines, barbiturates, methadone, propoxyphene, Quaaludes, Ecstasy/MDMA, & Oxycodone/Percoset.
The
article says,
"Chitwood said Thursday that it was Daniel Kelsey who tested 'presumptive positive' for drugs. The sheriff said there was a 'presence of weed' in his urine. However, Chitwood also added that the toxicology tests done on the couple may show other substances."
This leads me to believe that all that has been performed thus far is a standard UDS. A false negative on a UDS would be extremely rare and those are usually the result of purposeful manipulation. Therefore, at this point, all of this talk about other drugs is nearly a moot point. The only thing we have to go on is that they found Daniel Kelsey to be positive for cannabis. Cannabis didn't cause his death.
