Understanding How Depression Can Lead to Drug Relapse

Depression is a serious and chronic mental health condition that affects the way a person thinks, feels, and performs daily activities. While it is normal to feel upset when something bad happens or to have a low mood from time to time, persistent feelings of sadness and worthlessness are far more serious.

People who struggle with depression are more likely to abuse drugs and alcohol. Similarly, people who are addicted to drugs and alcohol are more likely to experience symptoms of depression.

The most reliable addiction treatment centers in Massachusetts address dual diagnosis disorders like drug addiction and depression to provide patients with the best possible chance at long-term recovery. This is because untreated mental health conditions, including depression, can lead to drug relapse and unsuccessful treatment outcomes.

The Relationship Between Depression and Drug Addiction

Mood disorders, including depression and bipolar disorder, are the most common mental health conditions that co-occur in people who struggle with substance use disorders (SUDs). Approximately 32% of people with any type of mood disorder also struggle with substance abuse. A majority of individuals with mood disorders struggle with depression. Researchers estimate that 16.5% of people with depression have an alcohol use disorder and 18% have a drug use disorder. And, when compared to individuals without a mood disorder, people with depression were twice as likely to develop a SUD.[1]

Individuals who struggle with depression experience long periods of low mood, energy, and motivation. These symptoms can become chronic and can seriously impact a person’s quality of life. Many people with depression will try various antidepressant medications only to find little relief. Unfortunately, chronic depression can tempt a person to try self-medicating.

While drugs and alcohol may feel as though they can elevate mood and energy in the short term, they are not a suitable long-term solution. In fact, substance abuse can alter brain chemistry and depression worse. It can even cause depressive symptoms to develop in people who had previously not struggled with depression before.

Unfortunately, leaving depression untreated or ignored during the recovery process can increase a person’s risk of drug relapse.

Symptoms of Depression

Depression, also known as clinical depression or major depressive disorder, is a common yet serious mental health condition. While major depressive disorder is the most common type of depression, there are other types of depression, as well. These include:[2]

• Persistent depressive disorder (dysthymia)
• Postpartum depression
• Seasonal affective disorder (SAD)
• Bipolar disorder
• Psychotic depression

The different types of depressive disorders are characterized by how often, how long, and how intense a person experiences symptoms. Symptoms of depression include:[2]

• Persistent feelings of sadness, anxiety, or emptiness
• Feelings of pessimism or hopelessness
• Irritability
• Feelings of guilt or worthlessness
• Low energy and fatigue
• Loss of interest in activities or hobbies
• Moving or speaking slowly
• Restlessness
• Difficulty concentrating, making decisions, or recalling events
• Appetite or weight changes
• Difficulty sleeping or oversleeping
• Suicidal thoughts or attempts
• Digestive problems that do not ease with standard treatment

Why is it Important to Treat Both Depression and Addiction?

Left untreated, depression can increase the intensity of drug cravings and reduce overall treatment outcomes.[1] Chronic symptoms of depression can even lead to a potentially dangerous drug relapse. Even if a person with a history of depression seems “cured” in early recovery, it’s important to remember that these feelings of elation are common but temporary in early recovery.

Some people who get sober experience a phenomenon called the “pink cloud.” While on the “pink cloud,” individuals feel better than they’ve ever felt before. They feel as though they are doing great things in sobriety, aren’t going to relapse, and have everything under control. They may even present with increased confidence, energy, and mood. However, when the pink cloud wears off (as it is always bound to do), untreated symptoms of depression can pick back up where they left off.

Ignoring past symptoms of depression or thinking one’s depression is cured can be a major mistake. Individuals may leave rehab without the proper tools to cope with depressive symptoms. They may get discouraged, aggravated, and even tempted to start the merry-go-round of self-medication once again.

While the ACA mandates insurance companies to cover mental health and addiction rehab services, it does not specify whether or not they have to provide coverage for all facilities. For instance, your insurance provider may cover treatment at one rehab in Massachusetts but not the next. That is because there are in-network and out-of-network options. In-network options are usually cheaper.

To figure out who is in-network with your insurance provider, you can do one of two things:

How Can Untreated Depression Lead to Drug Relapse?

Depression can significantly increase the risk of relapse when it goes unrecognized or untreated. The symptoms of depression are often deeply distressing and may include persistent sadness, hopelessness, low energy, and a loss of motivation. As these symptoms worsen, individuals may struggle to complete daily responsibilities or remain engaged in recovery activities that support sobriety.

When depression interferes with participation in treatment or support systems, such as therapy sessions or 12 step meetings, the protective structure of recovery can begin to erode. People may gradually withdraw from healthy routines and return to familiar coping behaviors that once provided temporary relief, even if those behaviors are harmful.

Over time, the emotional strain of untreated depression can intensify cravings and impair decision making. In an effort to escape emotional pain or regain a sense of normalcy, some individuals may turn back to substance use as a form of self medication. Addressing depression through professional mental health care is a critical component of relapse prevention, as treating both mood symptoms and substance use together supports long term recovery and emotional stability.
