Quick answer
Not reliably detected by standard amphetamine screens; a dedicated assay is needed. Urine is typically positive for about 1–2 days. In Arizona, marijuana status is: Recreational + medical legal.
Detection windows in Arizona
| urine | |
|---|---|
| Any use | roughly 1–2 days (specialised assay) |
| saliva | |
| Any use | hours |
| hair | |
| Any use | detectable on specialised testing |
| blood | |
| Any use | hours |
Detection windows are the same nationwide; only state law and workplace policy differ. Ranges vary with dose, frequency and the assay.
Testing in Arizona
Arizona's adult-use law explicitly states it does not restrict an employer's ability to enforce workplace policies or drug testing. A positive test can still be used in employment decisions, and a medical card does not shield an employee from testing.
Arizona does not require employers to accommodate off-duty cannabis use; the Smart and Safe Arizona Act explicitly preserves employer drug-testing and workplace policies.
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.
