What link with suicide is considered the MOST deadly?

Substance abuse is often considered the most deadly link with suicide due to several interrelated factors. Individuals struggling with substance abuse may experience heightened impulsivity and impaired judgment, which can lead to an increased risk of self-harm and suicidal behavior. Additionally, substances like alcohol and drugs can exacerbate existing mental health issues, creating a cycle where the individual is both more vulnerable to mental health challenges and more likely to engage in self-destructive patterns.

The combination of substance abuse with mental illness is particularly concerning, as it can diminish an individual's ability to cope with stressors and may lead to feelings of desperation or hopelessness. Furthermore, substance abuse is associated with social isolation and emotional trauma, both of which can contribute to suicidal thoughts and actions.

This multifaceted relationship highlights why substance abuse stands out as a critical factor in suicide risk, emphasizing its role in undermining an individual's protective factors and overall mental well-being.
