I'm co-founding CannabisReset with James Langton, author of The Quit Cannabis Handbook — turning a book that treats cannabis addiction as an emotional problem, not a willpower problem, into an interactive recovery companion. Currently in development, UK-first.

Strategic Insight
Nearly every quit-cannabis app on the market is a day counter. Streaks, sober-day tallies, money saved. Useful — until the first lapse resets the counter and the shame does the rest.
The book behind CannabisReset makes a different argument: cannabis dependence is emotional self-suppression. People smoke to mute boredom, anxiety, anger, sadness, fear. Recovery isn't counting days without weed — it's relearning to feel.
That thesis maps onto a genuine market white space: every competitor counts days, and almost none address the feelings underneath. CannabisReset tracks feelings, not just sober days.
Following the Evidence
Before designing anything, we studied 18 months of listening data from the book's audiobook edition. One number stood out:
54%
of listeners drop off in the first hour
Withdrawal
the exact chapter where they stop
~230k
daily cannabis users in the UK alone
People don't abandon the book because it stops being good — they abandon it at the moment the content turns to withdrawal, which is exactly the moment their own discomfort peaks. A linear book can't meet someone in that moment. An app can.
From Chapters to a Living Programme
The core product decision was to refuse the obvious build — a book-reader with a chatbot bolted on. Instead, each chapter became its own product surface, organized into three layers:
The Spine
A time-gated journey mapped to the real quit timeline: preparation, quit day, the first 24 hours, the withdrawal weeks. The programme meets you where you are in time.
The Library
Everything on demand: emotional deep-dives, hypnotherapy recordings, meditations, the audiobook chapter by chapter, and quick in-the-moment techniques.
The Daily Loop
A ten-second feelings check-in that routes you to the right tool for how you actually feel right now — plus an SOS craving flow and a weekly reflection that surfaces your trigger patterns.



A Companion With James's Voice
The centre of the experience is an AI companion grounded entirely in the book — James Langton's actual thinking, methods, and warmth, available at 2am when a craving hits. His voice, recorded and cloned with his participation, reads alongside you.
The guiding principle for every design decision: the app is James walking beside you. His lines, his non-judgmental framing, his "cut down or quit — your choice" stance. The voice is the moat, because therapeutic alliance is what drives recovery — and retention.
Underneath the warmth sits a clinical toolkit. The companion draws on a library of CBT, DBT, and ACT techniques — each grounded in the evidence for what it can and can't do — and matches them to the exact moment: urge surfing and distress-tolerance skills when a craving peaks, cognitive reframing when a thought spirals, playing the tape forward when "one joint won't hurt" shows up, behavioural activation when the day has gone sideways. Never the same tool twice in a row, never breathing exercises by default.

A real exchange: a late-night craving is met with urge surfing ("it's a wave — let it move through you"), a one-minute *Ride the wave* audio in James's voice, playing the tape forward ("it only ever shows you the first frame, never the rest of the reel"), and behavioural activation to move the energy out.
CBT, DBT, and ACT techniques, chosen to match the moment — delivered in James's voice.A companion, not a clinic
Medical disclaimers in onboarding and every conversation, crisis signposting to real help, and a hard rule: this is a companion to the book, never AI therapy or medical advice.
The Business We're Building
- A fixed-length programme, not an open-ended subscription — a finite commitment mirrors how people actually quit, and how the book is structured.
- B2C first, B2B next — prove the programme with individuals, then bring it to universities, therapists, and public health services.
- UK-first — real crisis resources, UK spelling, and a focused market of roughly 230,000 daily users before expanding.
James owns the method, the story, and the relationships. I own the product: strategy, design, AI system, and the build itself — applying the same operating model I developed founding Loop Mind.
Where It Stands
Working prototype
Onboarding, the daily loop, the companion, and the library are functional and being refined with James ahead of launch.
Evidence-led scope
Every major decision — quit-first audience, programme pricing, emotion-first design — traces back to data or the book's tested method.
A repeatable pattern
Author-owned method plus AI companion plus founder-led build: a model for turning trusted recovery content into living products.
Built on a proven method
James Langton's workshops and book already work offline. The product's job is to carry that method to people the book alone can't reach.
Building a product intelligence function?
If you're building in mental health, digital health, or regulated care and don't have a product function yet, or have one that's not working, I'd love to hear about it.
