Conn. Gen. Stat. § 21a-422b

A drug test of a student that yields a positive result solely for 11-nor-9-carboxy-delta-9-tetrahydrocannabinol shall not form the sole basis for an educational institution to refuse to enroll or to continue to enroll, or otherwise penalize such student, unless failing to do so would put the educational institution in violation of a federal contract or cause it to lose federal funding, or such student is being drug tested as required by the National Collegiate Athletic Association and any such action is taken as required by the policies of the National Collegiate Athletic Association.
