Drug addiction and depression have always had a very complicated and intertwined relationship. Substance abuse and mental illnesses like depression are found together so frequently that doctors came up with a term for the co-occurring disorders, dual diagnosis. According to The US Department of Health and Human Services, individuals who suffer from major depression have higher rates of alcoholism and drug addiction. This same study found that more than 1 out of every 5 adults who experienced an episode of depression in the previous year also engaged in substance abuse. These daunting statistics left researchers wondering, which came first, the drug addiction problems or the depression?
How Substance Abuse Can Lead to Depression
Substance abuse can lead to depression in a variety of ways. Experts agree that extreme and prolonged substance abuse can cause psychiatric problems in those addicted. Symptoms of depression are commonly reported as are hallucinations to a lesser extent. Depressive symptoms can develop as a result of a current alcohol or drug addiction like with alcohol for example, a known depressant. Depressive symptoms can also come as a result of withdrawal symptoms or a “come down” from the high of a drug like cocaine. There are instances when the depression can be short-lived when coming as a result of substance abuse but there are instances as well where the symptoms turn into a full blown, prolonged illness.
