Testing in Alabama
Alabama allows workplace drug testing and employers may act on positive results. A medical card does not shield an employee from testing, and state law does not require employers to accommodate off-duty use.

About MDPV
MDPV is a synthetic cathinone associated with the early 'bath salts' wave. It is not part of standard employment panels.
Standard amphetamine screens often miss it; a dedicated mass-spectrometry assay is required.
As with other designer stimulants, the detection window depends on the specific compound and assay.
