Some of the largest reductions in national suicide rates have occurred when access to a commonly used and highly lethal suicide method was reduced. Consequently, reducing a suicidal person's access to lethal means of suicide ("means restriction") is a vital component of any effective national strategy for reducing suicide rates. Reducing access to firearms is particularly important given their greater lethality compared with other methods commonly used in US suicides and the very short deliberation period preceding nearly half of suicide attempts. Nonetheless, means restriction interventions remain uncommon. The CDC's recently released Research Priorities for the National Center for Injury Prevention and Control, acknowledges this gap and calls for evaluation of the feasibility, scalability, and economic efficiency of means restriction strategies.
