High-functioning addiction is one of the most misunderstood forms of substance use disorder, and also one of the most dangerous.
It does not scream for attention. It whispers behind social charms and hides in the gaps of school runs and completed deadlines. From the outside, everything looks fine, perhaps even enviable, while inside, a quiet battle is raging.
What is high-functioning addiction?
High-functioning addiction refers to a person living with a substance use disorder while still appearing to maintain control over their daily life. A high-functioning addict will consistently meet their daily responsibilities and work deadlines, and they may appear to be outwardly successful, all while hiding a destructive relationship with drugs or alcohol behind an unshakeable façade.
Most of us can relate to having moments where we’re anxious or on edge. At that moment, we endeavour to appear like we’re in control. We might use breathing exercises or return to our most cherished memories to find a moment of solace within the chaos.
Yet most of us won’t choose to quell our discomforts in the fleeting comfort of drugs.
A person with a high-functioning addiction will turn to a substance and continue to function and carry out their responsibilities. But the ability to function isn’t the same as being well, and when left untreated, it is patently inevitable that, at one point, something will have to give.
Why does high-functioning addiction often slip under the radar?
One of the most dangerous aspects of high-functioning addiction is how easily it can hide in plain sight. It raises the unsettling question: Can you be addicted and not know it? For many high-functioning individuals, the answer is yes.
We can all probably admit that when we first paint a mental picture of addiction, it appears chaotic, strewn with slurred speech, nights passed out and a lifestyle that is generally collapsing, emotionally as much as financially.
So when someone becomes skilled at displaying outward success, few of us will stop to question whether they are struggling with a substance behind the scenes.
A person with a high-functioning addiction will learn to compartmentalise multiple areas of their life. They manage to show the world that their professional and personal life is always shimmering with success, and any internal turmoil is kept exactly there: inside, hidden from others.
A high-functioning addict may even use their achievements as a way to deny outside questioning: “If I were truly addicted, I wouldn’t be able to do this well, would I?” So a silent truth is ignored, giving the addiction more time to quietly entrench itself.
Warning signs of high-functioning addiction
High-functioning addiction won’t arrive with loud indicators or overt signals. It can be hard to recognise indicators, as signs of addiction often manifest in subtle ways. These may include:
- Mood swings and irritability when substance use is disrupted: A change in routine that seems relatively minor to you might provoke an outsized emotional response in a person hiding an addiction.
- A growing web of justifications: You might feel like this person has a pre-loaded set of excuses for using the substance, like “I’m still outperforming everyone else” or “I need this to continue doing so well.”
- Increasing reliance on a substance to “perform”: You might notice this person using a substance as a crutch before big meetings, social events or creative work, all the while hiding their use from the larger audience.
- Slow but steady neglect of personal well-being: You might notice them getting poor sleep or skipping meals. Additionally, high-functioning addicts may seem much worse in the mornings, before their responsibilities for the day arise.
Which industries carry the highest risk for addiction?
One characteristic of high-functioning addiction is the fact that a person still carries out their job as normal, or even excels at it. High-functioning addiction isn’t confined to one area of work, but research on addiction in professionals from SAMHSA shows some significant variations across different sectors:
- Mining (heavy alcohol use: 17.5%) and Construction (16.5%) had the highest rates of heavy alcohol consumption among full-time workers.
- Accommodations & Food Services saw the highest rates of illicit drug use (19.1%) and overall substance use disorders (16.9%).
- Education, Health Care, and Public Administration Industries consistently recorded the lowest levels of heavy drinking, drug use, and addiction.
There may be several overlapping factors that relate to trends found in some industries. Stressful and physically demanding environments demand harder labour with long hours and high rates of injury. We may see workers in these industries leading to self-medication.
Access and social norms in the workplace cultures of some industries may create an aura of normalisation in substance use. We may be influenced by stereotypes such as frequent cocaine use in high-pressure sales environments, or some sectors with specific demographics may be more prone to working while under the influence.
High-functioning addiction often thrives in environments such as these because workers may excel on the job while struggling privately. Some industry cultures seldom challenge the status quo of how they operate, so addiction may sadly become a common way of “coping” with the demands.
Why treatment still works, even if life hasn’t fallen apart yet
One of the most harmful misconceptions about addiction and recovery is that you need to “hit rock bottom” before you get help. To understand the dangers, we need only think about how each person has their own tolerance towards a drug, or how rock bottom will never look the same for two people. To believe that rock bottom must be met before treatment may in fact cost many people their lives through fatal overdose.
In many ways, the fact that many people still function well professionally while being addicted is proof that a person can be deeply unwell, even when their life appears stable from the outside. Some research highlights how 9.5% of full-time workers in the U.S. were dependent on or abused alcohol or illicit drugs in the previous year, which indicates that the problem runs deeper than we know.
A person shouldn’t wait for a job loss or medical emergency to justify getting treatment. The earlier a person starts treatment, the easier it is to reverse harmful patterns before they’re unmanageable.
Therapy in rehab is one of the most powerful ways a person can unravel the silent drivers behind addiction. A person can move from silently struggling with addiction to managing their life with healthier, sustainable coping mechanisms. While there are some differences in outpatient vs inpatient treatment, the key is starting a plan tailored to your lifestyle and readiness for change.
Treatment does not need to be a matter of tearing down every aspect of your life. It can be perfectly suited to preserving the parts you’ve worked so hard to build, like your career and your relationships. In sobriety, you can find a deeper sense of control as you step into the healing light of recovery, freeing yourself from the invisible but torturous weight you’ve been carrying.
