Aluminium phosphide is one of the commonest poisons used for suicides in northern parts of India. A study has been conducted on the cases of aluminium phosphide poisoning brought for autopsy at the mortuary of U.C.M.S. & G.T.B. Hospital, Delhi. It was observed that males are commonly involved than females. Incidence is more common during 3rd decade of life and is rarely used for homicidal purposes.

Estimates for pesticide suicides in South East Asia are dominated by patterns of suicide in India (SE Asia mortality stratum D), whose population (1,050 million) accounts for 81% of the 1,293 million people living in stratum-D of the region. Official data for 2005 suggest that 19.6% (n = 22,327) of India's 113,914 officially recorded suicides were self-poisonings with insecticides<58>. A particular feature of self-poisoning in northern India is the frequent ingestion of aluminium phosphide, a fumigant used to protect grain stores, with an associated case fatality in excess of 70% <12>. The WHO estimate that 55% of suicides in Bangladesh (SE Asia-D), the third most populous country in this region (population 144 million), are by self-poisoning<59>. Data from other sources indicate that a large proportion of these fatal poisonings are pesticide ingestions<60,61>. Our estimates for stratum-D are based on official suicide statistics from India<58> and, using data presented in Table 2, an estimated range in the proportion of suicides that employ pesticides in India of 20% to 30%.
we used to use it in grain storage bins its stinks to high heavens of garlic/chemical smells, I cant even imagine drinking or eating it!!
