Definition of Substance Induced Mood Disorder

Substance Induced Mood Disorder is a kind of depression that is caused by using alcohol, drugs, or medications. Substance/Medication-Induced Depressive Disorder is the diagnostic name for alcohol or drug induced depression. Unlike the transient feelings of sadness that are normal and that everyone experiences, or even the temporary hangover or "crash" that often gets people the morning after alcohol or drug use, when substance induced depression hits, it feels considerably worse for much longer.

For some people, it involves a complete loss of interest or enjoyment in life.

The irony of substance induced depression is that most people take drugs to feel better, yet those same drugs make them feel worse. For this reason, people sometimes don't realize that it is alcohol, drugs or medications that are causing the way that they are feeling because they only associate those substances with positive emotions.

When doctors or psychologists give a diagnosis of substance/medication-induced depressive disorder, they check to make sure that the depression wasn't there before the use of alcohol, drugs or medications thought to be responsible. This is because there are different types of depressive disorders, and if the symptoms were there before the substance use, it isn't the substance/medication induced type of depression.

How Soon After Taking the Drug Can Depression be Induced?

In some cases, almost immediately.

There is even a category "with onset during intoxication," which means that depressive episode actually begins when the individual is high on the drug. It can also occur during withdrawal, during which symptoms of depression are common. However, with depression which is simply a symptom of withdrawal, the person's mood will usually pick up within a few days of ceasing to take the drug, while with substance induced depression, it can start during withdrawal, and continue or get worse as the person moves through the detox process.

Generally, the diagnosis isn't given if the person has a history of depression without substance use, or if the symptoms continue for more than a month after the person becomes abstinent from the alcohol, drugs or medication.

Finally, for the diagnosis of Substance/Medication-Induced Depressive Disorder to be given, there has to be some sort of significant impact that the change in mood is having on the person's life, either by causing a great deal of distress, or by impairing some aspect of their life, such as their social life, their employment situation, or another part of their life that is important to them.
