What Is Harm Reduction? Why I Use It in Therapy

I am a harm reduction therapist through and through. When clients show up in my office and confess that they’ve been engaging in behaviors that are causing harm— to themselves, their relationships, or other parts of their lives— I am always firstly curious about what those behaviors are doing for them. Perhaps they are drinking more than they want to, using cannabis in ways that have become costly, doom scrolling late at night for hours at a time, or having sexual experiences that leave them feeling less connected to themselves. Many times they tell me that they are responding in relationships in ways they recognize are hurting themselves or other people– big protest behaviors, passive aggression, control and manipulation strategies. 

I want to be explicit here: that harm needs to be taken seriously. They are showing up in my office in vulnerability wanting something to change. 

And, at the same time, as a harm reduction therapist I always approach these moments with a trauma-informed lens that asks: How is this behavior functional? How is it supporting their system? Was it once incredibly adaptive, and has it now become costly in a different context?

These questions help us understand what needs to change and what support will make that change more possible. For as we know, simply identifying a behavior as unhealthy does not necessarily help someone stop relying on it and integrating something new.

Harm reduction involves moving away from an all-or-nothing approach to change. We work toward reducing harm, improving wellbeing, and increasing choice, without requiring someone to achieve perfect abstinence before their progress counts or they deserve support.

In substance-use care, harm reduction can include safer-use strategies, reduced use, treatment, and at times, abstinence. The National Harm Reduction Coalition explicitly includes abstinence within its approach, alongside an emphasis on dignity, individual needs, and quality of life. So harm reduction does not mean being opposed to sobriety. For some people, abstinence is their preferred goal or the safest option. What I am interested in is whether the approach fits the person, their neurotype, their lived experience, culture and background, and does it take the risks seriously and give us a workable way forward.

In my practice, I also bring this philosophy into how we approach other costly patterns. That is a broader clinical application of the principles, rather than a claim that substance-use research establishes how every relationship behavior should be treated.

A behavior can be harmful and still serve an important function. Weed may help someone quiet an otherwise relentless internal experience of noise, criticism, shame and pain. Drinking may make social connection feel more possible. A person may seek sexual attention because it offers a temporary experience of being wanted. Someone who is controlling in a relationship may be reaching for those control tendencies because uncertainty feels intolerable in their body.

Those are possibilities we explore, rather than explanations we assume. Not every behavior comes from trauma. Habits, dependence, genetic predisposition, social circumstances, access to support, and present-day stress also matter.

But when a behavior has become a reliable way of managing something difficult, asking someone to remove it without understanding what it provides can leave a significant gap. 

What will help them sleep, tolerate loneliness, manage overwhelm, or remain present during conflict? What alternatives are genuinely available, rather than theoretically good ideas they cannot yet access? I often adopt a coherence-informed lens here: what makes this response understandable within the person’s lived experience? How have conditioning and earlier learning shaped what feels necessary now?

Understanding the function gives us somewhere more useful to begin. We can work on reducing the immediate harm while also developing other ways to meet the need.

Something I love about harm reduction is its destigmatizing stance. In my clinical work, I often find that shame makes it harder for people to speak honestly about what is happening. They may minimize, avoid the subject, or arrive already convinced that they have disappointed me.

I want clients to be able to tell me the truth, because when the truth is on the table we have all the data to work with. If they used more than they intended, returned to an old habit, or behaved in a way they regret, we need room to understand that experience without turning the session into another place where they are humiliated. We can ask what happened before the behavior, what it offered in the moment, and what the consequences were. We can consider what support was missing and what needs to happen differently.

Accountability remains part of the conversation, of course. The person can take responsibility for a harmful action without making that action the entirety of who they are. In my experience, that distinction can make the work more accessible.

There is research supporting alternatives to abstinence-only treatment goals, although we need to be specific about what it shows. A systematic review of 22 studies involving adults with alcohol use disorder compared controlled-drinking and abstinence-oriented approaches. Across the five randomized trials, the researchers did not find a statistically significant difference in achieving the review’s drinking-threshold outcome. Some nonrandomized findings favored abstinence, and the evidence had limitations. The authors concluded that abstinence need not be the only treatment approach and that controlled-drinking goals can be a viable option, particularly with appropriate psychotherapy.

It’s important to name that that does not establish moderation as equally safe or effective for every person. But it does support having more than one pathway into care, with goals informed by the person’s circumstances and risks. For me, that is an important distinction. We do not need to insist on one definition of progress in order to take change seriously.

When I work with ADHD or other neurodivergent clients, I want to understand whether the strategy we are using fits how that particular person functions. Are we accounting for sensory needs, difficulty initiating tasks, fluctuating capacity, or the amount of effort daily life already requires?

For some clients, maintaining a perfect sobriety streak becomes less helpful than looking at their pattern over time. Imagine someone who has been sober on 80 or 90 percent of days during a particular period. If the only measure is an uninterrupted streak, one day of use can make all the preceding work feel erased.

We might instead track the collection of days they did not use, what helped on those days, and how quickly they returned to their plan after difficulty. The earlier progress still exists. There is something to learn from it.

That is not a universal rule about ADHD or autism. Some neurodivergent people find streaks motivating and supportive. There is not established evidence that cumulative tracking is inherently better for a particular neurotype. I am describing an individual adaptation I may use when the existing measure is producing more shame than useful information.

NICE’s ADHD guidance similarly emphasizes tailoring environmental modifications to the individual’s assessed needs. It does not prescribe this sobriety-tracking method, but it supports the broader importance of adapting support to the person.

And sober days are only one measure. We also need to look at what happens on days of use, including quantity, loss of control, and consequences. A high percentage of sober days can coexist with serious harm.

When this philosophy enters relationship work, the distinction between understanding and permission is essential.

We can explore why someone becomes critical, retaliatory, or controlling while remaining clear that the behavior needs to stop. A partner should not be asked to tolerate abuse while the other person gradually develops insight.

Sometimes immediate protective action is necessary. Sometimes specialized treatment or a different level of care is needed. Harm reduction is also used in high-risk situations; the seriousness of the risk makes appropriate intervention more important, not the person less deserving of compassionate care.

My trauma-informed stance helps me approach the person without dehumanizing them. It does not diminish the impact on anyone they have hurt.

We begin with what is happening, what it costs, and what the client wants their life to look like. Depending on the situation, we may work on reducing use, changing the circumstances around it, accessing additional treatment, or developing other ways to manage the experience the behavior has been helping them hold.

We review whether the plan is actually reducing harm. Gradual change is not automatically the right approach, and a plan that is not working needs to be reconsidered. Alcohol dependence, for example, may require medical support because abruptly stopping can cause dangerous withdrawal.

What I value about harm reduction is the room it gives us to remain engaged with the person’s actual life. We can recognize a meaningful shift without pretending the work is complete. We can discuss a setback without treating it as the loss of everything that came before.

Perhaps someone returns to an old behavior and tells me sooner than they once would have. Perhaps they recognize the urge earlier, accept support, or make a different choice in a situation that has usually felt automatic. We can take those changes seriously while continuing to address what remains harmful. There is more information available, and more of the person available to work with it.
