Back in 2012, the Army awarded a grant to Dr. Michael Kubek of the Indiana University School of Medicine to develop an “anti-suicide nasal spray”. TheMarySue.com gives some details:
The Military Suicide Research Consortium offers some more info, similarly emphasizing that a primary benefit of the nasal spray was that it would be quick-acting. So I’m assuming the idea was that if someone was thinking about suicide, they could squirt the spray up their nose and the thoughts would go away. Although this suggests a problem. If someone was serious about suicide, wouldn’t they purposefully not use the nasal spray?
