The NICS Improvement Amendments Act of 2007 (NIAA) requires states, as a condition of grant eligibility, to establish procedures to allow persons with disabilities relating to mental health (i.e., prohibiting mental health adjudications or involuntary commitments to a mental institution) to obtain relief from such disabilities for purposes of firearms eligibility. The 33 states in this list have qualified relief of disability programs, under 18 U.S.C. §§ 922(d)(4), (g)(4), that ATF has approved.
