What if the same moment of emotional pain could split into two dangerous paths, one where a person tries to numb the feeling with alcohol or drugs, and another where they try to release it through self-inflicted harm? For many people, these responses don’t exist separately. They can intertwine, feeding into each other and forming a cycle that becomes harder to escape with time. Substance use can also impair judgment and increase impulsivity, which may raise the risk of self-harm in vulnerable situations. In this blog, we will explore why self-harm and substance use often overlap, how they can reinforce one another, and what effective, integrated treatment looks like for addressing them together. What Is Self-Harm? Self-harm is intentionally injuring oneself as a way of coping with emotional distress. When the behavior occurs without an intent to die, clinicians may refer to it as non-suicidal self-injury (NSSI). However, self-harm and suicidal thoughts can occur in the same person, so every instance should be taken seriously. Self-harm may include: Cutting or scratching the skin Burning oneself Hitting or punching oneself Interfering with wounds so they do not heal People may self-harm to temporarily reduce overwhelming emotions, communicate distress, regain a sense of control, or interrupt emotional numbness. The reason is different for each person. As per the study published in the National Library of Medicine, self-harm is not simply attention-seeking behavior, and it should not be dismissed because the person does not intend to die. A professional assessment can help determine the person’s immediate safety and underlying needs. What Is Substance Use Disorder? Substance use disorder (SUD) is a medical condition involving continued alcohol or drug use despite significant problems or consequences. A person with SUD may have difficulty controlling their use, experience strong cravings, or continue using substances even when use is affecting relationships, work, school, finances, or health. Substances involved can include: Alcohol Opioids Cocaine Methamphetamine and other stimulants Cannabis Misused prescription medications Occasional substance use does not automatically mean someone has SUD. Diagnosis depends on the person’s pattern of use and the effects it has on their life. Is There a Link Between Self-Harm and Substance Abuse? Yes. According to the National Institute on Drug Abuse, self-harm and substance abuse can share underlying psychological and environmental risk factors, including trauma, emotional distress, depression, anxiety, impulsivity, and difficulty regulating emotions. The relationship can also reinforce itself. Someone may use substances to numb distress, experience worsening emotions or consequences afterward, and then turn to self-harm for another form of relief. Conversely, a person who already self-harms may use substances when emotional triggers become difficult to manage. This does not mean substance use directly causes self-harm in every case. Instead, both behaviors may develop from similar underlying struggles or make one another more difficult to manage. Why Do Self-Harm and Substance Use Occur Together? There is rarely one explanation. Several factors can contribute to the overlap. Emotional Pain Depression, anxiety, shame, loneliness, anger, or guilt can become difficult to tolerate. Alcohol, drugs, or self-harm may provide temporary relief from those feelings, even though they do not resolve their underlying causes. Trauma and Adverse Experiences Abuse, neglect, violence, bullying, or other traumatic experiences can affect how a person responds to stress and emotional pain. Trauma does not guarantee that someone will develop addiction or self-harm behaviors, but it can increase vulnerability. Difficulty Regulating Emotions Some people experience emotions very intensely or have difficulty calming themselves once distressed. Without healthy coping skills, an immediate behavior may feel easier than processing what they are experiencing. Impulsivity Impulsive behavior can play a role in both substance misuse and self-harm. When someone is intoxicated, their ability to pause, evaluate consequences, and make safer decisions may be further reduced. Shared Risk Factors Several mental health and environmental factors can increase the likelihood of experiencing both substance use problems and self-harm. These may include: Depression Anxiety disorders Post-traumatic stress disorder (PTSD) Borderline personality disorder (BPD) Childhood abuse or neglect Chronic stress Bullying Social isolation Family history of addiction or mental health conditions Having a risk factor does not mean someone will develop either condition. These factors simply help clinicians understand where additional support may be needed. How Can Substance Use Increase the Risk of Self-Harm? Substance use can create additional risk, particularly when someone already has a history of self-harm. Intoxication can lower inhibitions and impair judgment, making it harder to resist an urge or consider the consequences of an action. Some substances can also increase agitation, anxiety, paranoia, or emotional instability. Withdrawal can create another challenge. Depending on the substance, withdrawal may involve anxiety, irritability, sleep problems, agitation, cravings, or other distressing symptoms. For someone already struggling with self-harm, these experiences may make emotional regulation more difficult. This is one reason professional assessment matters. Stopping certain substances suddenly can also carry medical risks, so detoxification and withdrawal management should be guided by qualified professionals when clinically appropriate. Warning Signs of Co-Occurring Self-Harm and Substance Abuse One isolated change does not prove that someone is struggling with both conditions. However, several changes occurring together deserve attention. Possible warning signs include: Unexplained injuries or frequently covered injuries Frequent intoxication or suspected substance misuse Increased secrecy Sudden mood changes Withdrawal from friends or family Declining work or school performance Changes in sleep or appetite Increased isolation Expressions of hopelessness or feeling trapped If someone talks about wanting to die, has a suicide plan, or appears to be in immediate danger, treat it as an emergency rather than waiting for a regular treatment appointment. Call or text 988 for crisis support or call 911 for a life-threatening emergency. How Are Self-Harm and Substance Use Diagnosed? Professionals generally look at the entire picture rather than diagnosing based on one behavior. An assessment may explore: History and frequency of self-harm Current and past substance use Mental health symptoms Trauma and significant life experiences Medications and physical health Suicidal thoughts or behavior Relationships and home environment Previous treatment and recovery attempts A suicide
