Which of the following is considered an environmental risk factor for suicide?

Access to lethal means and toxic substances is recognized as a significant environmental risk factor for suicide. The availability of methods that individuals can use to harm themselves influences the likelihood of suicidal behavior. When individuals have easy access to firearms, prescription medications, or other lethal means, the risk of completed suicide increases, especially in moments of crisis when impulsive decisions are most likely.

In contrast, supportive family members, strong community social support, and engagement in regular physical activities are protective factors against suicide. These elements provide emotional support, promote a sense of belonging, and contribute to overall mental well-being, which can mitigate risk rather than enhance it. Access to lethal means stands out distinctly as a factor that can directly elevate the risk of suicide in an individual.
