We cannot offer legal advice. If you have individual liability/malpractice insurance contact your carrier. You can also contact www.taana.org The American Association of Nurse Attorneys as they have a referral service. TAANA | Attorney ReferralPositive drug screens are reportable to the board of nursing and/or the alternative to discipline board. (in NJ the organization is called RAMP). You can also self-report if you want. NJ State Nurses Association: RAMP
