Any substance consumed in excess can result in poisoning.
Poisoning is a significant factor in both unintentional and intentional injury-related deaths, as well as in injury hospitalizations, in BC.2 In 2021/22, unintentional poisoning ranked as the second highest cause of injury hospitalizations for children aged 4 years and younger in BC. Unintentional poisoning is one of the top five causes of injury hospitalizations among 5 to 84-year-olds.3 In 2020, over a third of all cases reported to poison centres across Canada involved children aged 5 years and younger.4
Substances that result in a poisoning, and the populations at risk of poisoning, vary greatly by intent and lethality. Alcohol, drugs, or medicinal agents are the main substances that result in over 90% of unintentional poisoning deaths and 85% of poisoning hospitalizations.
Medication (including prescribed and over-the-counter) is the leading cause of poisoning in children. Other products that can be poisonous to children include:
Both unintentional and intentional poisonings are common injuries among Canadian teenagers and adults. Common substances involved include:
Unintentional poisoning among older adults typically involves:
Intentional poisoning may also occur, commonly involving:
Poisoning from substances—such as illicit drugs, prescribed and over-the-counter medications, alcohol, pesticides, gases, and household cleaners—is the leading cause of injury-related death and the second leading cause for injury-related hospital admission in BC. We examined the health and economic costs of poisoning in BC for 2016, using a societal perspective, to support public health policies aimed at minimizing losses to society. Results were published in CMAJ Open.
The first study described the events and circumstances preceding children aged 16 years and younger being treated for cannabis poisoning in the emergency department (ED) of a Canadian pediatric hospital, prior to the national cannabis legislation. A follow-up study is looking at ED visits for cannabis poisoning at the same hospital post-legislation. Read the results of the first study.
Using a large linked administrative dataset from PopDataBC, the pathway and risk factors between an injury and an illicit drug overdose event were explored. Specifically, this project aimed to determine whether opioid prescription, opioid agonist therapy, whether the injury was work-related, and the profession affected the risk of overdose. Results were published in Health Reports.
The study will describe the burden of the current overdose epidemic in BC in terms of hospitalizations and their outcomes.
Current evidence suggests the following best practices to prevent poisoning-related events or reduce their effects:
