AZ HB2541

Amends Arizona drug testing laws by adding definitions for "current use of any drug," "good faith," "impairment," and "safety-sensitive position" to clarify employer drug testing policies.

Expands employer protections from litigation to include actions based on good faith belief that an employee used drugs or was impaired while working, and allows exclusion from safety-sensitive positions based on good faith belief of current drug use.

Adds severability clause to Title 23, Chapter 2, Article 14 to preserve the validity of remaining provisions if any part is found invalid.

Extends the medical marijuana registry verification system to allow employers to verify registry identification cards provided by current employees or applicants with conditional job offers.

Takes effect retroactively to April 12, 2011, and requires a three-fourths affirmative vote in both legislative houses for the section amending the verification system to become effective.
