Cannabis Use Disorder Treatment in Europe, What This 2025 Overview Adds, and What It Still Cannot Tell Us

This is a mixed-methods mapping paper, not a treatment trial, and it offers a useful snapshot of how cannabis-specific services are distributed across Europe, while leaving major questions unanswered about quality, outcomes, and real-world access.

Why This Matters

Cannabis use disorder is not a fringe issue in this paperโ€™s framing. The authors describe cannabis as the most frequent reason for first-time drug-related treatment admissions in Europe, and they note that between 8% and 22% of lifetime cannabis users may develop cannabis use disorder. That makes treatment availability a practical public health question, not just an academic one. At the same time, a map of services is not the same thing as proof that people are receiving high-quality, evidence-based care.

What This Paper Looked At

This paper gathered information on cannabis-specific treatment programs across 27 EU member states plus the United Kingdom, Norway, and Turkey, for a total of 30 countries. The authors used a mixed-methods approach, combining a survey of National Focal Points connected to the European Drugs Agency, a qualitative review of internal drug and treatment workbooks from 2020 and 2021, and follow-up contact with national experts when details were missing. Programs were only included if they were structured, theory-driven, and specifically tailored to people with cannabis-related problems. Preventive interventions and general harm-reduction strategies were outside the paperโ€™s scope.

What the Paper Found

The broad finding is that cannabis-specific treatment exists in parts of Europe, but coverage remains patchy. Sixteen of the 30 countries reported cannabis-specific programs. Fifteen countries reported face-to-face cannabis-specific interventions, and nine reported online information, self-help, or therapist-guided programs. The paper also notes that many countries still rely primarily on general substance use treatment programs rather than dedicated cannabis-specific care. Online options appear to have expanded after the COVID period, and the authors describe early emergence of designated cannabis clinics in a few settings, especially for patients with cannabis use disorder plus psychosis or other psychiatric comorbidity.

How Strong Is This Evidence?

As evidence, this paper is best understood as a structured policy and service landscape review. It is useful for showing what kinds of programs are reported to exist and where obvious gaps remain. It is not designed to test whether one treatment works better than another, whether access is equitable, or whether patients actually improve. In the evidence hierarchy, that makes it informative for service mapping and planning, but much weaker for clinical decision-making than randomized trials, prospective outcome studies, or high-quality systematic reviews of treatment efficacy.

Where This Paper Deserves Skepticism

The biggest limitation is that the paper depends heavily on country-level reporting, internal workbooks, survey responses, and personal communication. That means the picture may be incomplete, uneven, or partly dependent on how national respondents interpreted the questions. The authors explicitly acknowledge that some cannabis-specific approaches may exist at national, regional, or local level without being consistently described in the documents they reviewed. They also acknowledge that for the UK, information came only from personal communication, which may limit validity. Just as importantly, the paper states that most reported programs are not evidence-based, and that little information was available on clinical outcomes or treatment manuals. So the paper can tell us more about reported availability than about actual effectiveness.

What This Paper Does Not Show

This paper does not show that Europe has solved cannabis use disorder treatment. It does not show that cannabis-specific programs are widely accessible, uniformly implemented, or supported by strong outcome data. It also does not show that online treatment expansion has translated into durable clinical benefit. For vulnerable groups, including adolescents, people with severe mental illness, pregnant women, older adults, and others with more complex needs, the paper mainly highlights scarcity rather than resolution. Readers should be careful not to confuse the existence of named programs with proof of broad, effective care.

How This Fits With the Broader Clinical Conversation
The paper aligns with a familiar tension in addiction medicine: clinical need often grows faster than specialized service infrastructure. It also reinforces a more specific point about cannabis use disorder. Even where psychosocial approaches such as cognitive behavioral therapy, motivational enhancement therapy, and contingency management have supporting evidence, enduring abstinence remains difficult, and no pharmacotherapy has been approved for cannabis use disorder. In that context, a growing patchwork of specialized and online programs is encouraging, but it is still not the same as a mature, evidence-based treatment system.
Dr. Caplan’s Take
What catches my attention here is not a dramatic therapeutic breakthrough, but something quieter and more important. This paper shows that health systems across Europe are at least trying to build more tailored responses for people struggling with cannabis use. In practice, that mirrors a real clinical question patients and families ask all the time: where do I go when cannabis has stopped being helpful and started becoming a problem? The useful part of this paper is that it treats that question seriously. The part I would be careful with is the gap between program availability on paper and confidence that patients are truly getting effective, evidence-based care.
In real care, I would not treat this paper as proof that a particular national model is working especially well, or that dedicated cannabis treatment is now broadly available. I do think it adds something useful to the conversation, because it makes clear that cannabis use disorder deserves tailored attention and that generic addiction infrastructure may not be enough for every patient. But I would still want to think through severity, co-occurring psychiatric symptoms, age, family context, readiness for change, and the quality of local services before drawing any practical conclusion for an individual patient.
What a Careful Reader Should Take Away

This paper makes a modest but meaningful contribution. It suggests that cannabis-specific treatment services in Europe have grown over the past decade, especially through regional face-to-face programs and newer online offerings. But the bottom line remains cautious: coverage is still limited, many services are not clearly evidence-based, and the literature on real-world outcomes remains thin. It is a helpful map of a developing treatment landscape, not a confirmation that the landscape is strong enough yet.

Frequently Asked Questions

Does this paper show that Europe has strong cannabis use disorder treatment coverage?

No. It shows that cannabis-specific programs exist in parts of Europe, but coverage remains limited and uneven, and many programs are not clearly evidence-based.

Is this a treatment trial?

No. This is a mixed-methods mapping paper that describes reported treatment availability across countries. It does not test whether one treatment works better than another.

What is the most important limitation?

The paper depends heavily on national reporting, internal workbooks, survey responses, and some personal communication. That makes it helpful for landscape mapping, but weaker for judging real-world quality or outcomes.
