Testing in Arkansas

Arkansas does not broadly protect off-duty cannabis use in employment; employers may still enforce drug-free workplace policies and test under state law.
About Khat (cathinone)
Khat is a plant whose leaves contain cathinone, a stimulant chemically related to amphetamine. Standard amphetamine immunoassays often do not detect it.
Detection generally requires a dedicated mass-spectrometry assay; a negative standard panel does not rule out khat use.
Cathinone degrades quickly after harvest, which is one reason its presence is difficult to standardise across tests.
