What causes addiction?

Ask most people and you will probably hear familiar answers.

Peer pressure.

Wanting to have fun.

Bad friends.

Experimenting with drugs.

Making bad choices.

A lack of willpower.

There is some truth in parts of these explanations. Peer influence, early exposure, family environment, availability and life experiences can all influence someone’s vulnerability to addiction. But none of them, on its own, explains why one person can experiment and walk away while another eventually develops a serious substance-use problem. Addiction develops through a complex interaction of biological, psychological, social and environmental factors.

And this is where the conversation needs to go deeper.

Because addiction is rarely just about the substance.

The Myths About What Causes Addiction

“It was just peer pressure.”

Peer pressure can influence whether someone tries alcohol or drugs, particularly when they are young. Friends, family environment and early exposure can all influence substance-use risk.

But peer pressure doesn’t explain the whole story.

Thousands of people are encouraged to try something and never develop an addiction.

So the more important question is:

What happens after the first experience?

What does the substance do for that person?

How does it make them feel?

What does it temporarily take away?

And what was already happening in their life before they picked it up?

“They just wanted to have fun.”

Sometimes they did.

People may initially use substances because they are curious, want to feel good, want to fit in or enjoy the effects.

But the reason someone starts using a substance isn’t necessarily the reason they eventually can’t stop.

Someone may begin drinking because they enjoy partying.

Later, they may drink because they can’t relax without it.

Then because they can’t sleep.

Then because they don’t feel confident in social situations without it.

Eventually, they may no longer be drinking for fun at all.

They may be drinking to feel normal.

The beginning of addiction and the reason addiction continues can be very different things.

“They made bad choices.”

People are responsible for their behaviour and the consequences of their actions.

But calling addiction simply a series of bad choices doesn’t explain why repeated substance use can affect reward, craving, judgement, decision-making, stress regulation and behaviour. Over time, the brain can adapt to repeated drug exposure, contributing to tolerance and increasingly powerful cravings.

It also doesn’t explain why people with very different backgrounds can develop addiction.

There is no single “addictive personality”.

There are, however, combinations of risk factors that can increase vulnerability.

And that is where things become much more interesting.

What Was Happening Before the Addiction?

Before the alcohol.

Before the cocaine.

Before the cannabis.

Before the methamphetamine.

Before the gambling.

Before the increasingly destructive behaviour.

There was a person.

A person with a history.

A person with emotions.

A person with relationships.

A person with fears, insecurities, experiences and coping mechanisms.

Sometimes the addiction becomes the most visible part of someone’s life while the things underneath it become almost invisible.

That is why understanding what causes addiction requires us to look beyond the substance.

Some People Feel Things Very Deeply

Some people experience emotions intensely.

They may be highly affected by criticism, rejection, conflict or changes in relationships. They may think deeply about things other people seem able to let go of. They may struggle to switch their thoughts off or become overwhelmed by emotions they don’t know how to manage.

Sensitivity itself isn’t a weakness.

But if someone has never learned how to understand, express and regulate what they feel, intense emotions can become difficult to live with.

And when emotional discomfort becomes overwhelming, people naturally look for ways to change how they feel.

For one person, that might be exercise.

For another, talking to someone.

For another, alcohol or drugs.

The substance can become a shortcut to changing an internal state.

That is why emotional regulation can become an important part of addiction recovery.

When You Don’t Know How to Say What You Feel

Some people were never taught how to express difficult emotions.

They learned to keep quiet.

Don’t complain.

Don’t show weakness.

Don’t talk about what happened.

Just get on with it.

So anger may become the only emotion they know how to express.

Pain may become frustration.

Fear may become aggression.

Shame may become withdrawal.

Sadness may become drinking.

Anxiety may become drug use.

The person isn’t necessarily consciously thinking, “I am going to use this substance to deal with my emotions.”

The connection can develop gradually.

This is why effective addiction treatment needs to look at more than the behaviour itself.

It needs to help a person understand what is happening underneath it.

Mental Health and Addiction Can Become Closely Connected

Mental health and substance use can influence one another.

Some people misuse alcohol or drugs as a way of coping with psychological distress. At the same time, substance use can contribute to or worsen mental-health symptoms. Some people experience both a mental-health disorder and a substance-use disorder at the same time.

This can create a difficult cycle.

Someone feels anxious.

They drink to calm down.

The temporary relief reinforces the behaviour.

The alcohol then contributes to poor sleep, mood changes or further anxiety.

The person drinks again.

The cycle becomes stronger.

Alcohol itself is a psychoactive, dependence-producing substance and is associated with mental-health conditions including depression and anxiety.

The same principle can apply to other substances and other forms of psychological distress.

This is why addiction treatment should not only ask:

“How do we stop the person taking the substance?”

It should also ask:

“What is happening in this person’s emotional and psychological world?”

Our pages on Trauma and Addiction Treatment, Anxiety and Addiction Treatment and Depression and Addiction Treatment explore these connections in greater depth.

The Role of Coping Skills

Everyone experiences stress.

Everyone experiences rejection.

Everyone experiences grief, frustration, disappointment and fear.

The difference is often in how we respond.

Healthy coping skills don’t make difficult emotions disappear. They give us ways of dealing with them without automatically making the situation worse.

A person may need to learn how to:

recognise what they are feeling
identify what triggered it
communicate difficult emotions
tolerate discomfort
challenge destructive thought patterns
manage impulses
ask for support
establish healthy boundaries
deal with conflict
regulate intense emotions
develop healthier routines
recognise relapse warning signs

For someone whose substance use has become their primary coping mechanism, developing alternative ways of dealing with life can become a fundamental part of recovery.

Why Do Some People Keep Chasing a Higher High?

This is where addiction can become progressively more entrenched.

The first experience can feel powerful.

But repeated exposure to some drugs can lead to tolerance. The brain adapts to repeated drug exposure, reducing its response to the substance and meaning that more may be needed to produce the effects previously experienced.

And this can create a dangerous pattern.

The first amount doesn’t feel the same.

So the person takes more.

The effect still isn’t what it used to be.

They may increase the amount, use more frequently or begin seeking a stronger experience.

What started as:

“I want to feel good.”

Can gradually become:

“I need to feel something.”

And eventually:

“I need this just to feel normal.”

That is one of the cruel paradoxes of addiction.

The person can spend increasing amounts of time and energy chasing an experience that becomes progressively harder to achieve.

The pursuit continues even while the consequences become increasingly obvious.

The Progressive Nature of Addiction

Addiction can become progressive, but there is no universal timeline that every person follows.

Some people develop serious problems quickly.

Others use substances for years before the consequences become obvious.

Some experience periods of heavy use followed by periods of abstinence.

Others develop a pattern that becomes increasingly difficult to control.

What can happen, however, is that problematic substance use becomes increasingly entrenched.

Occasional use can become regular use.

Regular use can become a routine.

The routine can become something the person feels unable to control.

Eventually, obtaining and using the substance can begin taking priority over relationships, work, health, finances and responsibilities.

A person may continue using despite knowing that it is damaging their life.

That loss of control is one of the defining features of substance-use disorder.

And the progression isn’t always obvious from the outside.

Someone can maintain a job.

They can look successful.

They can exercise.

They can maintain relationships.

They can tell everyone they’re fine.

And still be developing a serious addiction.

The Truth About “Gateway Drugs”

The term gateway drug is often used to describe the idea that using one substance leads to the use of more dangerous substances.

There can be patterns of progression between different substances, and earlier substance use is associated with greater risk of later problematic use. Peer influences, early exposure, availability and the characteristics of the substance itself can all play a role.

But we need to be careful with the idea that one drug automatically leads to another.

It doesn’t.

Someone who uses cannabis, for example, does not inevitably progress to cocaine, heroin or methamphetamine.

The people who do progress may also have underlying vulnerabilities that influence both their initial substance use and later patterns of use.

So rather than saying:

“This drug causes people to move on to harder drugs,”

it is more accurate to recognise that early and repeated substance use can be part of a broader pattern of increasing vulnerability, while biological, psychological, social and environmental factors also matter.

The important issue is not simply which substance someone starts with.

It is the relationship they develop with substances and the reasons they continue using them.

Addiction Can Change What You Are Chasing

In the beginning, someone may be chasing pleasure.

Later, they may be chasing relief.

Eventually, they may simply be trying to escape discomfort.

The motivation can shift from:

“I want to get high.”

to:

“I want to stop feeling.”

And eventually:

“I don’t know how to feel normal without it.”

At this stage, telling someone simply to stop can miss the psychological reality they are experiencing.

Stopping the substance matters.

But what happens next matters too.

What will they do when anxiety returns?

How will they cope with rejection?

What happens when grief comes back?

How will they handle anger?

Who will they talk to?

What will they do when the urge to use appears?

Those are recovery questions.

Addiction Is Not Just About the Substance

This is why addiction treatment needs to look beyond the substance itself.

A person may need to understand their history.

They may need to explore trauma.

They may need help with anxiety or depression.

They may need to develop emotional regulation.

They may need to learn how to communicate.

They may need to rebuild their self-esteem.

They may need to understand their triggers.

They may need to learn how to tolerate uncomfortable emotions without escaping from them.

They may need to develop healthier coping mechanisms.

And they may need to recognise the thinking patterns that can lead them back towards substance use.

This is where our broader Mental Health and Addiction work becomes relevant.

Co-occurring mental-health and substance-use disorders are common, and when both are present, treatment may need to address both.

Emotional Intelligence, Impulse and Addiction

Recovery also involves learning to create space between an emotion and an action.

You feel angry.

You don’t have to act on the anger.

You feel anxious.

You don’t have to immediately escape it.

You feel rejected.

You don’t have to reach for a substance.

You feel an urge.

You don’t have to obey it.

That pause can be enormously important.

Emotional intelligence isn’t about never experiencing difficult emotions.

It is about becoming more aware of what you are feeling, understanding what may be driving it and learning to respond rather than automatically react.

For someone recovering from addiction, that can become a practical skill.

What am I feeling?

What triggered it?

What am I wanting to do right now?

Where could that action take me?

What could I do instead?

These are simple questions.

But learning to ask them before acting can create a completely different response to difficult moments.

Sobriety Is Essential. But It Is Not the Whole Story.

Getting sober is a critical first step.

But sobriety does not automatically teach someone how to live differently.

A person can stop drinking and still have no idea how to manage anxiety.

They can stop using drugs and still be unable to express anger.

They can leave treatment and still be overwhelmed by rejection.

They can remain abstinent while carrying the same thought patterns, coping mechanisms and unresolved difficulties that existed before treatment.

This is why lasting recovery requires more than simply removing the substance.

It requires developing the ability to face life without automatically escaping from it.

That may involve therapy, emotional regulation, relapse prevention, healthy routines, relationships, personal responsibility and learning new ways of coping.

Looking Within Is Part of Recovery

Perhaps the most important question isn’t:

“Why can’t they just stop?”

Perhaps it is:

“What happened before the addiction?”

What were they feeling?

What were they trying to escape?

What did they never learn to express?

What did they believe about themselves?

What situations triggered them?

What did alcohol or drugs give them that they didn’t know how to get in healthier ways?

And what skills do they now need to develop so they don’t need the substance to cope?

These questions don’t excuse destructive behaviour.

They help us understand it.

And understanding creates the possibility of change.

What Causes Addiction? The Answer Is Deeper Than the Drug

There is no single cause of addiction.

Biology matters.

Environment matters.

Early exposure matters.

Mental health can matter.

Trauma can matter.

Stress can matter.

Relationships can matter.

Coping skills can matter.

And repeated substance use can reinforce the cycle by changing the way the brain responds to reward, stress and decision-making.

But perhaps the most important thing to understand is this:

Addiction is rarely just about the substance.

The substance may be the thing we can see.

The underlying struggle may be much harder to see.

That is why recovery needs to go deeper than sobriety.

It means learning to recognise what you feel.

Learning to express what you feel.

Learning to regulate what you feel.

Learning to cope with what life throws at you.

Learning to pause before acting on an impulse.

Learning to deal with difficult experiences without automatically escaping.

And ultimately, learning that you can experience difficult emotions without being controlled by them.

Recovery isn’t simply learning how to live without alcohol or drugs.

It’s learning how to live without needing them to cope with life.
