Cannabis at Work: Testing Rules, Rescheduling, and Safety

Marijuana rules keep shifting across states while federal rescheduling remains in play. This session maps what matters for programs: THC vs CBD and hemp derivatives, impairment vs presence, and DOT vs non-DOT differences. Coverage includes test matrices and detection windows, panel and cutoff strategy, confirmation workflows, and MRO considerations, as well as policy considerations for safety-sensitive roles, accommodation touch points, and manager messaging.

Key Learnings:

  1. Regulatory and policy snapshot. State trends, federal rescheduling steps, DOT and non-DOT contrasts.
  2. Testing realities. Method and matrix differences, detection windows, delta-8 and other hemp variants, confirmation and cutoff choices.
  3. Program implications. Safety-sensitive focus, accommodation and discipline touch points, policy language, and documentation.
