If you are depressed or thinking about suicide, call 12356 (China's national mental-health hotline), and don't keep a stock of sleeping pills or pesticide at home

In plain words

Evidence keeps growing that putting deadly means out of reach works: after painkillers were restricted, related suicides fell 43%; at places where people often jumped, adding barriers cut suicides there by 86%. So don't stock sleeping pills or pesticide at home. When you can't see a way out, call 12356 first — it works nationwide in China and is staffed at least 18 hours a day.

Cost

Free. One phone call. Also lock up medicines and keep pesticide out of the house.

What you get

A systematic review of the past 10 years of research found that the evidence for restricting access to lethal means keeps getting stronger. After painkillers were controlled, painkiller-related suicides fell 43%. At sites where people often jumped, barriers cut suicides by 86% (79% to 91%, the plausible range for this figure). School-based cognitive programs lowered suicide attempts by about 55% (OR 0.45, 95% CI 0.24 to 0.85). Antidepressants and psychotherapy are an important part of suicide prevention. Since May 1, 2025, dialing 12356 anywhere in China connects to a psychological support hotline, open at least 18 hours a day

Notes

Why grade B: most of the evidence on restricting means comes from ecological studies that compare numbers before and after a policy; the hotline itself has no evidence of lowering deaths. Suicidal urges often last only minutes to hours, so moving deadly things one step further away is an intervention in itself. For data on this time scale and on long-term outcomes after an attempt, see §1.32 (tell one person as soon as a suicidal thought comes up). For what is left behind after being saved, see §1.33.

Evidence grade
B : Supported by research but without a precise number, or based on small or single studies.
