Studies show that people who are dependent on drugs or alcohol attempt suicide six times more often than people who do not abuse drugs.
Furthermore, more than 90 percent of people who die by suicide suffer from depression, have a substance abuse disorder or are struggling with both.
These figures, while alarming, make sense at least in the way that those who are severely depressed often turn to drugs to help them cope if they cannot find a more positive avenue to deal with their feelings.
Specifically relating to opioids, users have an a 40 to 60 percent increased likelihood of suicidal thought, and a 75 percent increased likelihood of a suicide attempt. Because, like suicide, drug abuse has historically been a stigmatized subject, addicts are often isolated from family and loved ones as well, which also can amplify both depression and suicidal thoughts.
