Medical Marijuana in connecticut – This is a State with specific employee protection – Conn. Gen. Stat. §21a-408 et seq.; Dept. of Consumer Protection Reg. §21a-408-1 et seq. Connecticut employment protections included:

  • Prohibits refusing to hire, discharging, penalizing, or threatening employee solely on basis of person’s medical marijuana status as qualifying patient or primary caregiver
  • Allow discipline based on marijuana use or impairment on the clock

Intoxication Defense – States vary in their willingness to allow employers to use an injured worker’s intoxication as a defense against a claim for compensation.  State laws’ intoxication defenses generally fall into one of three rough categories: defenses that do not depend on causation; defenses that require some form of proximate causation between intoxication and injury; and defenses that require that intoxication be the sole cause of injury.  Always check with your insurance company and your attorney when you have a positive post-accident test after an injury.

State and local law varies greatly; therefore, you are advised to consult experienced legal counsel during the design of your actual substance abuse testing program and with any questions that follow.
