PTSD and Addiction

If exposure to a life-threatening event leads to long-term distress, or if your reaction to it becomes chronically and significantly disabling, you might have post-traumatic stress disorder (PTSD). Some people with PTSD may use drugs and alcohol to manage their symptoms and go on to develop addiction.

Ideally, people with PTSD and addiction should have both issues treated at the same time. Treatment may consist of both therapy and medication. Research continues to uncover more about these two conditions and the most effective forms of treatment.

What Is PTSD?

Not everyone who experiences a traumatic event will develop PTSD, and a variety of factors may influence whether someone develops it. For example, women are more likely to have PTSD than men.3

Overall, 3.5% of U.S. adults have PTSD.1,2 However, this rate is higher among military veterans and those whose occupations increase the risk of exposure to traumatic events, such as firefighters, emergency medical personnel, and police.1


After a traumatic event, a number of symptoms must surface for the person to meet the criteria for a diagnosis of PTSD:1

Some combination of the above symptoms must be present for at least 1 month for the person to meet the criteria for PTSD. Also, the symptoms must affect important areas of functioning, such as school, work, the ability to maintain relationships with others, or the ability to take care of oneself. Lastly, the symptoms must not be due to other factors, such as another medical condition or substance use.1

Why Do People With PTSD Use Drugs?

Those who struggle with PTSD may feel frustrated and hopeless. Unfortunately, many turn to unhealthy coping mechanisms such as drinking and using other substances. Research shows that almost half (46.4%) of those with PTSD also meet criteria for a substance use disorder. In the vast majority of cases, the development of PTSD precedes the development of an addiction.4

If a person has a substance use disorder, they might: 1

Using substances to alleviate symptoms of PTSD is called self-medicating. People who self-medicate may believe that they are reducing their PTSD symptoms. But they are likely creating more issues. For example, some of the symptoms of drug withdrawal may be similar to symptoms of PTSD, including sleep disturbances, difficulty concentrating, feelings of detachment, and irritability. The person may use again to alleviate these symptoms and begin a reinforcing cycle that can lead to addiction.4

This theory suggests that the lifestyle of those who use substances typically involves spending time in dangerous environments or participating in high-risk behaviors associated with obtaining or using substances. This may increase the likelihood that they will experience a traumatic event and eventually develop PTSD.4

Other factors that may influence the development of concurrent PTSD and substance use disorders are genetics, shared abnormalities in certain areas of the brain, and prior exposure to traumatic stressors. Further, military veterans are at an increased risk for both PTSD and substance use disorders, with more severe combat exposure linked to an even higher risk of developing long-lasting PTSD symptoms.4

Those who have both PTSD and a substance use disorder typically experience more issues than those who have one disorder or the other. For example, those with both disorders tend to have increased chronic physical health issues, poorer social functioning, higher rates of suicide attempts and other mental health concerns, more legal problems, more financial problems, an increased risk of violence, poorer treatment outcomes, and less improvement during treatment.4,5

PTSD and Substance Abuse Treatment

In the past, it was common to treat comorbid PTSD and substance use disorder separately. In fact, the substance use disorder was often treated first, and the treatment of PTSD would be put off until the person was sober for a period of time.4

Recently, treatment courses have changed. The integrated model of treatment is used to address both the substance use disorder and PTSD at the same time. The person may see the same clinician for both treatments, rather than seeing 2 separate professionals.4 This approach helps address the complexity of comorbid symptoms, since some may overlap. Further, the person can address triggers and emotions linked with their substance use, which can help foster and maintain recovery.


Research has found that sertraline, which has been approved for the treatment of PTSD, may additionally help reduce alcohol use in people with earlier onset of PTSD. Disulfiram and naltrexone have also been found to help with abstinence. Desipramine, an antidepressant sometimes used to manage neuropathic pain, may improve alcohol use outcomes as well.4

Currently, the most researched medications for PTSD are antidepressants, which may help reduce symptoms. Research has also shown that prazosin may help with sleep issues, especially nightmares.3


For maximum effectiveness, prescribed medications are often combined with other treatment approaches, such as individual or family therapy.

Some of the types of therapy that have been used to treat both PTSD and substance use disorders are:
