Is My Loved One Using Drugs to Cope With Mental Illness?

Why People Use Substances to Manage Emotional Pain

The self-medication hypothesis, developed by psychiatrist Edward Khantzian at Harvard Medical School, proposes that many people who develop substance use disorders are initially drawn to substances not randomly, but because those substances address specific psychological pain or psychiatric symptoms they do not know how to manage any other way. The choice of substance is not arbitrary: people tend to gravitate toward substances whose pharmacological effects most directly relieve the specific symptoms they are experiencing.

A person with severe social anxiety may drink because alcohol is the only thing that has ever made social situations feel tolerable. A person with PTSD may use cannabis because it blunts hyperarousal and intrusive memories. A person with depression may use stimulants because they temporarily lift the flatness and exhaustion that has become their baseline. These are not irrational choices, they are imperfect, self-discovered solutions to real clinical problems by a person who does not yet have better ones.

Any help from the substance will be short-lived and likely not what they really need. Drug and alcohol use can have harmful effects on mood and mental health, sleep, relationships, judgment, and physical health. The National Institute of Mental Health explains co-occurring substance use and mental disorders as complex and interconnected, mental health problems can create a risk of substance use, while substance use can also heighten mental health symptoms, leading families to observe the behavior cycle long before there is language for it.

Signs That Suggest Self-Medication May Be Occurring

No family can diagnose a co-occurring disorder, that requires clinical assessment. But these patterns are frequently observed by family members before any clinical evaluation takes place, and recognizing them can be an important first step. Self-medication doesn't always come with a red flag. Your loved one may insist they are just unwinding. Watch for patterns of when, why, and how they use.

None of these signs on their own is proof of a mental illness diagnosis, but together they suggest your loved one should see a professional who can assess both their substance use and mental health symptoms.

How Depression, Anxiety, and Trauma Can Drive Substance Use

Depression can make a person feel heavy, numb, hopeless, or disconnected. Using may help them feel something, feel nothing, or make it through a given day. If you love someone with an anxiety disorder, their body may feel like it is constantly under attack, they may be using substances to relieve physical tension or avoid a panic attack. If your loved one has experienced trauma, they may live with flashbacks, nightmares, and bodily responses to memories they wish they could turn off but cannot.

It is also important to ask what the substance is doing for the person. Is it helping them fall asleep? Quiet panic? Feel more confident? Forget something painful? Get through work? Avoid withdrawal? The answer can point to the underlying emotional or mental health need behind the behavior. These patterns do not excuse harmful substance use, but they can explain why stopping feels so difficult.

The Cruel Paradox of Self-Medication

The deepest problem with self-medication is that the short-term relief it provides masks a long-term worsening of both conditions. Substances do provide genuine symptom relief initially, which is why people use them and why they are so difficult to give up. But over time, the neurobiological effects of chronic substance use make the underlying mental health condition worse, require escalating doses to produce the same effect, and create physical dependence that adds withdrawal to the existing suffering.

NIAAA notes that alcohol use disorder often occurs with mental health conditions, and that recovery is more likely when both are addressed. That same rule holds for other substance use: if a person only treats substance use or only treats mental health symptoms, parts of the problem remain untouched.

Why Quitting Can Feel Threatening to the Person Using

To the family, stopping may seem like the obvious solution. To the person using, stopping may feel like losing their only tool. If they believe substances are the only way to sleep, socialize, calm down, or stop painful memories, the idea of quitting can feel terrifying. That fear can make them defensive, secretive, or resistant to treatment.

This is why professional support matters. A person may need safer coping skills, therapy for the underlying symptoms, medical guidance during withdrawal, medication management when appropriate, and a relapse prevention plan. Merck Manual explains that substance use disorders involve continued use despite problems and can include tolerance, withdrawal, and difficulty controlling use. MedlinePlus describes dual diagnosis as having both a mental disorder and a substance use disorder, and both need attention for recovery to hold.

How Families Can Talk About Self-Medication Without Blame

When families point fingers at substance use, people get defensive. A better approach is to connect your observations about the behavior and express concern rather than simply assuming it is to "get high." For instance, instead of "You just want an excuse to use," try: "I see that you're drinking when you're feeling anxious, and I'm worried you may not be getting the help you need to cope with that."

You can also ask direct but respectful questions: "Are you sleeping okay?" "Do you feel worse when you try to stop?" "Would you be open to talking to someone who understands both mental health and substance use?" If they deny the connection, you can still set boundaries around unsafe behavior while keeping the door open for help.

It may also help to speak with a treatment provider before your loved one agrees to care. Families can ask what an assessment looks for, what information is useful, and how to respond if substance use escalates. If the person is intoxicated, in withdrawal, suicidal, violent, or medically unstable, the priority is safety, not persuasion. In those moments, emergency support, crisis services, or medical care may be necessary before a longer treatment conversation can happen.

When Substance Use and Mental Health Need Focused Care

Dual diagnosis care means both concerns are assessed and treated together. This matters because symptoms can overlap. Withdrawal can look like anxiety or depression. Untreated trauma can increase relapse risk. Substance use can make mood swings or sleep problems worse.

If your loved one has both emotional distress and substance use, ask treatment providers whether both will be evaluated. Families can be compassionate without accepting unsafe behavior. You can avoid shaming language while still setting limits around money, driving, substances in the home, threats, or behavior that harms children. Clear support works best: "I love you, and I want you to get help. I cannot pretend this is not affecting the family."
