Living with post-traumatic stress disorder (PTSD) can affect almost every aspect of daily life. Traumatic memories, nightmares, anxiety, flashbacks, and difficulty sleeping can make even ordinary situations feel overwhelming. For some people, alcohol or drugs become a way to escape these experiences, quieten unwanted thoughts, or temporarily feel more in control.
What may begin as occasional substance use to manage distress can gradually develop into dependence or addiction. Although alcohol and drugs might provide short-term relief, they do not resolve the underlying trauma and can make PTSD symptoms more difficult to manage over time.
PTSD and addiction frequently occur together, but both conditions can be treated. Understanding how they interact is an important step towards breaking the cycle and finding healthier ways to cope.
What Is PTSD and How Can It Affect Everyday Life?
Post-traumatic stress disorder is a mental health condition that can develop after someone experiences or witnesses a traumatic event. This might include physical or sexual assault, domestic abuse, serious accidents, combat, childhood trauma, or other experiences involving actual or threatened serious harm.
Not everyone who experiences trauma develops PTSD. However, for those who do, the effects can continue long after the original event has passed.
Common PTSD symptoms include:
- Flashbacks and intrusive memories: Unwanted recollections that make someone feel as though the traumatic experience is happening again.
- Nightmares and sleep difficulties: Disturbing dreams, difficulty falling asleep, or waking frequently during the night.
- Hypervigilance: Feeling constantly alert, easily startled, or unable to relax.
- Avoidance: Staying away from people, places, conversations, or situations associated with the trauma.
- Emotional distress: Experiencing fear, guilt, shame, anger, anxiety, or emotional numbness.
- Difficulty concentrating: Struggling to focus, remember information, or manage everyday responsibilities.
These symptoms can be exhausting. Someone with PTSD may feel disconnected from others, struggle with relationships, or find it difficult to manage work and personal commitments.
For some individuals, alcohol or drugs initially appear to offer a way to switch off these feelings.
Why Do People with PTSD Turn to Alcohol or Drugs?
One reason PTSD and addiction can occur together is self-medication. This describes using alcohol or drugs in an attempt to manage psychological or emotional symptoms without addressing their underlying causes.
For example, someone experiencing frequent nightmares might drink alcohol before bed because they believe it helps them fall asleep. Another person may use cannabis to feel less anxious, take prescription medication outside medical guidance to numb emotional distress, or use stimulants to feel more alert when exhaustion becomes overwhelming.
These substances can temporarily change how someone feels, which may reinforce the behaviour. If drinking or using drugs appears to provide relief, the person may begin relying on them whenever PTSD symptoms become difficult to tolerate.
Over time, however, the brain and body can adapt to repeated substance use. Tolerance, cravings, and withdrawal symptoms may develop, making it increasingly difficult to stop.
The original reason for using substances may gradually become less important as dependence takes hold. What started as an attempt to manage trauma can become a separate problem requiring its own treatment.
The Connection Between PTSD and Alcohol Addiction
There is no single cause of binge eating. It can develop through a combination of biological, psychological, emotional, and environmental factors.
For some people, food becomes a way of managing difficult emotions. Eating may temporarily provide comfort, distraction, or relief from stress, loneliness, boredom, or anxiety. If this becomes a repeated coping strategy, a person may begin relying on food whenever uncomfortable feelings arise. Over time, a cycle can develop:
- An emotional trigger: Stress, sadness, loneliness, or anxiety creates an urge to eat.
- The binge: Eating provides temporary comfort or distraction, sometimes accompanied by a feeling of losing control.
- Emotional distress: Guilt, shame, or frustration follows the episode.
- Restriction: The person tries to compensate by skipping meals, dieting, or imposing strict food rules.
- Another binge: Hunger, emotional distress, or feelings of deprivation contribute to another episode.
This cycle can make binge eating increasingly difficult to manage without support. For some individuals, previous experiences of trauma, low self-esteem, depression, anxiety, or difficulties regulating emotions may also contribute. Genetics and environmental influences can play a role too.
Can Drugs Make PTSD Symptoms Worse?
Different substances affect the brain and body in different ways, but drug use can complicate PTSD symptoms and recovery.
Some people use cannabis because they believe it helps them relax or sleep. However, its effects vary, and it can contribute to anxiety, paranoia, memory difficulties, or other unwanted psychological effects. Current evidence does not establish cannabis as an effective treatment for PTSD.
Stimulants such as cocaine and amphetamines can increase alertness and energy, but they may also cause agitation, anxiety, sleep disruption, and heightened feelings of distress. These effects can be particularly difficult for someone already experiencing hypervigilance or problems regulating their emotions.
Opioids and sedative medications may temporarily numb emotional or physical pain, but they can carry significant risks of dependence, overdose, and withdrawal. Taking prescription medication differently from how it was prescribed can also create additional health complications.
The relationship between PTSD and substance use is not always straightforward. Trauma may contribute to substance use, substance-related situations may expose someone to further traumatic experiences, and both conditions can reinforce one another.
How PTSD and Addiction Create a Difficult Cycle
When PTSD and addiction occur together, each condition can make the other harder to manage.
A person may experience a flashback, nightmare, or period of intense anxiety and turn to alcohol or drugs for immediate relief. The substance may temporarily reduce distress, but its effects can wear off, leaving the person feeling anxious, exhausted, or emotionally unsettled.
They may then use again to escape these feelings. As substance use becomes more frequent, relationships, physical health, finances, and everyday responsibilities may begin to suffer.
This can create a cycle:
- Trauma symptoms: Flashbacks, anxiety, nightmares, or emotional distress become difficult to manage.
- Substance use: Alcohol or drugs are used to numb feelings or escape unwanted memories.
- Temporary relief: The person experiences short-term changes in mood or perception.
- Worsening difficulties: Sleep, mental health, relationships, or physical wellbeing may deteriorate.
- Increased reliance: The person turns to substances again to cope with the resulting distress.
Shame and secrecy can make this cycle even harder to break. Someone may feel embarrassed about their substance use or believe they should be able to manage their trauma without help.
It is important to recognise that this is not simply a lack of willpower. Both PTSD and addiction are complex health conditions, and professional support can help address the factors maintaining the cycle.
Recognising the Signs of PTSD and Addiction
It is not always easy to recognise when coping behaviours have developed into a substance use disorder, particularly when alcohol or drugs have become part of someone’s everyday routine.
Possible warning signs include:
- Drinking or using drugs to manage flashbacks, nightmares, anxiety, or emotional numbness.
- Needing increasing amounts of a substance to achieve the same effect.
- Experiencing cravings or struggling to control how much is used.
- Repeatedly trying to stop or reduce consumption without success.
- Feeling anxious, irritable, or physically unwell when not using.
- Avoiding social situations or responsibilities because of substance use.
- Continuing to use despite problems with health, relationships, work, or finances.
- Finding that PTSD symptoms or sleep difficulties are becoming harder to manage.
Not everyone with PTSD develops an addiction, and not everyone who uses substances has PTSD. A professional assessment can help establish whether one or both conditions are present and identify appropriate treatment..
Why Treating PTSD and Addiction Together Matters: How InnerLife Recovery Can Help
One of the most important considerations is that treating substance use alone may not address the trauma symptoms driving the behaviour. If someone stops drinking or using drugs but continues to experience severe nightmares, flashbacks, anxiety, or emotional distress, they may find it difficult to maintain recovery without additional support. Equally, treating PTSD without addressing an established addiction can leave someone struggling with cravings, withdrawal, and the effects of ongoing substance use.
