Youth Who Misuse Drugs Are More Likely to Commit Suicide

Suicide ranks among the top five causes of death among 15- to 19-year-olds. Research has shown that youth who misuse drugs are more likely to commit suicide than their peers who do not abuse substances. An estimated 27-50 percent of adolescents who committed suicide were found to display signs of substance use disorder.  

Many risk factors for suicide have been identified over the years, including limited access to health care, stigma, trauma, interpersonal issues, genetic and biological factors, hopelessness, mental health or substance use disorders, and family history of suicide. Substance abuse is frequently linked to suicides because it can increase impulsivity and interfere with mood. Conversely, positive interpersonal relationships, religious or spiritual beliefs, positive coping strategies, self-esteem and self-efficacy are all factors that contribute to individuals being less vulnerable to suicidal behaviour. Many of the protective and risk factors for suicidal behaviour are the same as the ones that put individuals at an increased or decreased risk of substance abuse. 

In a recent report the Canadian Centre on Substance Abuse (CCSA) summarized prevention and intervention efforts that are available for health care providers and others working with youth who are affected by substance use disorders and are at a higher risk of developing suicidal thoughts. The report also offers a list of recommendations for the development of effective prevention programmes that deal with substance use disorders as well as suicidal behaviour.
