Bans on Highly Toxic Pesticides Can Significantly Reduce Suicide Deaths

Excerpts from article By Hannah Ritchie | Edited for clarity and brevity

Suicide remains a leading global health concern, with over 700,000 deaths each year. In low- and middle-income countries, pesticide self-poisoning is a common method — accounting for an estimated 14% to 20% of all suicide deaths, or roughly 100,000 to 150,000 lives annually.

Evidence from several countries, particularly Sri Lanka, suggests that banning highly hazardous pesticides (HHPs) has significantly reduced these fatalities. Sri Lanka, once recording one of the highest suicide rates globally, has seen its suicide rate fall by nearly two-thirds since the 1990s. Research attributes much of this decline to phased bans on specific HHPs, including parathion, endosulfan, and paraquat.

The rationale is simple: when highly toxic substances are removed from easy access, the lethality of suicide attempts drops. Many individuals who survive an initial attempt do not go on to attempt suicide again. Substituted pesticides, while still harmful, are far less fatal — reducing the risk of death even when ingested.

Other countries, including Bangladesh, China, and India, have implemented similar bans with varying degrees of success. However, effectiveness often depends on enforcement, the availability of substitutes, and the prevalence of self-poisoning in each context.

Concerns about the agricultural impacts of such bans — particularly on food production and farmer incomes — are valid. Yet, available data shows no consistent decline in crop yields following targeted HHP bans. Blanket bans on all pesticides, such as Sri Lanka’s temporary 2021 prohibition, have had detrimental effects on food production and farmer livelihoods, underscoring the importance of targeted interventions over sweeping restrictions.

Cost-effectiveness studies estimate that a ban on HHPs in just 14 countries could prevent 28,000 suicide deaths annually at a cost of only $30 million. These findings suggest that, while not a substitute for comprehensive mental health care, restricting access to lethal means is a practical and scalable suicide prevention strategy.
