Testing in Colorado
Colorado permits workplace drug testing and employers may act on positive results, particularly for safety-sensitive positions. State legalization does not override an employer's drug-free workplace policy, and a medical card does not guarantee protection.
Colorado's lawful-off-duty-activities statute protects employees from discipline for lawful off-duty conduct, but courts have generally allowed employers to enforce drug policies and test for cannabis.
About Etizolam
Etizolam is a thienodiazepine with effects similar to benzodiazepines, but its structure differs enough that standard benzodiazepine immunoassays may not detect it.
Reliable detection generally requires a dedicated mass-spectrometry assay; a negative standard benzo screen does not rule out etizolam use.
It is not approved in the US and is scheduled in several states.
