When recovering from a substance abuse disorder, it is important to understand that addiction is rarely just about the substances that you are addicted to.
Whether your addiction involves alcohol, drugs or negative behaviours, addiction is deeply rooted in certain patterns of thinking that protect the individual from the uncomfortable truths.
These patterns are known as defence mechanisms and they play an important role in keeping addiction active, often long before a person ever considers a medical detox or rehab treatment.
Understanding these mechanisms is crucial when it comes to your addiction recovery.
Not only do these mechanisms explain why people struggle to accept help in the first place, but they also highlight why professional rehab and structured detox programmes are often necessary when it comes to breaking through the psychological barriers that addiction creates.
Defence mechanisms are unconscious psychological processes that protect us from negative feelings of anxiety, shame, or simply just emotional pain.
When it comes to addiction, these defence mechanisms distort reality and allow individuals to continue harmful behaviours, such as addiction, without fully confronting the consequences of their choices or of their addictions [1].
In addition to this, these defence mechanisms can create a false sense of control, minimise the severity of the problem, and delay the need for a medical detox or rehab treatment.
Put simply, defence mechanisms are not deliberate lies. Instead, they are deeply rooted mental habits that help individuals avoid emotional discomfort and protect themselves from the truths and reality of their current situation.
Defence mechanisms often develop in an addiction for many different reasons. For example, an addiction often brings intense feelings of guilt, shame, fear, depression and anxiety. Defence mechanisms emerge as a way to cope with these overwhelming, negative emotions.
Other common underlying drivers include the fear of stigma or judgement from other people, anxiety about withdrawal and the detox process, or a desire to maintain control or independence whilst they might feel out of control.
Likewise, people might develop a defence mechanism as a result of the emotional pain linked to trauma or mental health issues or the fear of life without addictive substances.
These mechanisms act as a psychological shield and whilst they may offer short-term relief from reality, they ultimately prolong addiction issues and delay entry into rehab treatment.
Let’s first examine why people experience denial. Denial is perhaps the most recognised defence mechanism when it comes to addiction and is often the most powerful mechanism that stops people from getting the treatment that they need.
Denial involves refusing to accept the reality of addiction or its consequences. It can be subtle or obvious, but its purpose is always the same, which is to avoid confronting the truth about their life or their addiction.
People in denial may genuinely believe that they do not have a problem, that they can stop whenever they want to or that their addiction issues are not affecting their life.
Denial often operates quietly and unconsciously, meaning that the person may not realise they are in denial at all. This can be incredibly hard to break through.
Denial allows addiction to continue by dismissing the consequences of their actions and by allowing the individual to avoid taking responsibility. By doing so, the individual sees no reason to get treatment or professional help.
It is also important to understand that denial can be reinforced socially by certain family members or friends who do not see a problem with their behaviour or addiction.
For example, if others around the person are using and abusing substances, then denial becomes easier to maintain.
The first step in recovery, whether you are entering a medical detox or rehab, is acknowledging the problem. Without this, meaningful change is extremely difficult, and the individual won’t feel the need to seek treatment.
Likewise, rationalisation is closely linked to denial. However, it operates in a slightly different way. Rationalisation involves creating logical-sounding reasons to justify negative and addictive behaviour.
For example, an individual using rationalisation might believe that they only use addictive substances when they are stressed, and therefore, it is not a big problem. They might also tell themselves that ‘everyone does it’ or that ‘it’s just a way to relax.’
Whilst these explanations often contain some truth, which makes them more convincing, they are often incredibly harmful.
Because rationalisation usually involves some truth and sounds reasonable, it can be harder to challenge for loved ones.
It allows individuals suffering from an addiction a reason and excuse to continue abusing addictive substances whilst maintaining a sense of control and self-respect. Over time, this delays treatment.
Justification is another key defence mechanism when it comes to addiction, often overlapping with rationalisation. Justification involves defending addictive behaviour using flawed logic or external circumstances.
For example, someone using justification as a defence mechanism might tell themselves that they work hard, so they have earned the right to enjoy themselves.
Likewise, they might tell themselves that their addiction isn’t a problem because they know people with worse habits or more severe addiction issues. They might also tell themselves that they can still function in day-to-day life, so there isn’t a problem.
These are all flawed points, and this type of reasoning and defence mechanism shifts the focus away from the harm being caused by their addiction and onto perceived reasons for continuing to abuse the addictive substances.
Essentially, justification allows individuals to maintain their behaviour without feeling guilty.
It also prevents the chance for honesty and self-reflection, which are both something that is essential when it comes to addiction treatment and an individual’s long-term recovery from an alcohol or drug addiction.
Avoidance is another type of defence mechanism when it comes to addiction issues. Avoidance involves deliberately avoiding and ignoring certain situations, conversations, or thoughts that highlight the addiction issue.
This may include changing the subject of addiction if it’s brought up, avoiding spending time with people who want to help them or refusing to attend interventions or appointments.
Likewise, people might start to ignore the physical or mental health symptoms associated with an addiction issue.
Avoidance can also show up as emotional withdrawal, which is when an individual refuses to engage with the reality of their addiction or mental health issues.
Avoidance is when an individual refuses to confront the need for treatment, whether that is a medical detox or rehab therapy.
This is because lots of people who suffer from an addiction issue use the logic that, as long as the problem is not acknowledged, it cannot be directly addressed. This massively delays acceptance and rehab treatment.
While denial, rationalisation, justification and avoidance are some of the most common defence mechanisms when it comes to addiction issues, there are several other mechanisms that frequently appear when someone is suffering from an addiction to drugs or alcohol. Some of these are listed below for you.
Minimisation is when someone starts to downplay the severity of their addiction issue by saying things such as ‘it’s not that bad’ or ‘I only abuse drugs or alcohol on the weekends.’
They tend to play down their substance use and make out that it is not that bad. This reduces the perceived urgency to seek a medical detox or rehab treatment.
Projection happens when an individual starts to attribute their own behaviours or feelings to other people. Essentially, they start to blame others for their substance abuse and addiction issues and start to accuse others of having the same or similar problems.
This defence mechanism shifts the issue and responsibility away from them and reinforces the addiction issue.
Blaming other, external factors is another common pattern for those suffering from an addiction issue.
For example, people suffering from an addiction issue will start to blame other people, their work or their childhood as a reason for their struggles.
This is often difficult to deal with, as whilst external stressors do play a role in addiction issues, blaming other people or things prevents accountability and delays treatment.
Intellectualising is another common defence mechanism, which involves overthinking and over-analysing addiction in a logical way, without addressing emotional reality.
For example, they might start talking about addiction statistics or research, or start talking about addiction as an abstract concept, rather than a personal issue of theirs. This is a way of detaching addiction from themselves.
It is important to understand that defence mechanisms do not just sustain addiction, but they actively interfere with treatment.
There are a number of different ways that these defence mechanisms make treatment harder, some of which are explained further below for you.
The above defence mechanisms cause a delay and resistance to treatment, especially when it comes to a medical detox.
Many individuals delay detox due to the fear of withdrawal or the belief that they simply do not need help in the first place. Defence mechanisms reinforce these beliefs, making it harder to take the first step into a medical detox.
Even if an individual manages to enter drug and alcohol rehab, defence mechanisms can still cause issues.
For example, they could cause a resistance to therapy, dishonesty during group sessions or an overall lack of engagement with treatment or aftercare plans.
Breaking down these defences is a core part of effective rehab, which is discussed further below for you.
Therapy is central to addressing the psychological side of addiction, especially when it comes to overcoming and breaking down the defence mechanisms that have prevented people from seeking treatment previously.
Addiction therapy helps to build awareness of addiction issues and different defence mechanisms. In fact, many people are unaware of how often they rely on denial or rationalisation as defence mechanisms throughout their life in general.
Your therapist will help you to identify when you use these defence mechanisms, understand any emotional triggers and develop healthier coping strategies.
Likewise, your time in therapy will help you to accept your addiction struggles and overcome any denial that you might be suffering from.
Your therapy sessions will be focussed on acknowledging your addiction, recognising the impact that it has had on your life and those around you and finally, accept the need for treatment.
Finally, your time in drug and alcohol therapy will help you to develop healthier coping mechanisms, rather than defence mechanisms.
This will usually involve learning how to better regulate your emotions, how to better deal with stress or anxiety and how to communicate with others more effectively [2].
When suffering from an addiction issue, it is important to understand that denial, rationalisation, justification, avoidance, and other defence mechanisms are not signs of weaknesses.
Instead, they are deeply rooted psychological responses to addiction and mental health issues.
However, in the context of addiction, they also become very high barriers to treatment and recovery.
Although these defence mechanisms make it a lot harder for individuals to acknowledge that they might need professional hope, with help and support they are capable of overcoming.
The important thing is being able to recognise these patterns and negative thought habits.
Whether through detox or rehab therapy, breaking through these defence mechanisms allows individuals to face up to the reality of their addiction or mental health issue, rebuild their lives and move forward towards their long-term recovery.
If you or someone you love is struggling with an addiction issue, then understanding these defence mechanisms could be the first step towards seeking the help that they both need and deserve.
