  • AIM: Determine major substances and risk factors for suicide by chemical overdose in New Zealand between 2001 and 2005. METHOD: All intentional deaths between 2001 and 2005 were reviewed. Primary substances causing death were verified from toxicology reports. RESULTS: The chemical suicide rate was higher among older Europeans, women and those in paid work than other groups. Carbon monoxide and tricyclic antidepressants (TCAs) continue to be the most common chemicals used, in spite of market changes. Anaesthetics and cyanide deaths among workers were noted. CONCLUSION: Restricted access to work-related chemicals and stricter prescription/dispensing controls for TCAs may reduce self-poisoning in New Zealand.
