Cannabis Rehab Cost in the UK
The short answer
Cannabis rehab in the UK typically costs £4,000–£7,000 for 28 days at a mid-market private clinic and £9,000–£15,000 at premium providers. Cannabis needs no medical detox, so many people are treated as outpatients for £500–£2,500 instead.

Cannabis Rehab cost by length of stay
Length of stay is the single biggest driver of what you pay. These are 2026 UK market ranges across CQC-registered private clinics — the clinic confirms the final figure after assessment.
| Length of stay | Typical private cost | What it covers |
|---|---|---|
| Detox only (no medical detox required) | £2,000–£4,500 | Medically supervised withdrawal and stabilisation, no therapy programme. |
| 14 days | £2,400–£9,000 | Detox plus a short therapy block. Common where time off work is limited. |
| 28 days | £4,000–£15,000 | The standard full programme: detox, group and 1-to-1 therapy, aftercare plan. |
| 60–90 days | £7,200–£39,000 | Extended treatment, usually after a previous relapse or with dual diagnosis. |
What moves the price
- Outpatient therapy is often clinically appropriate, which changes the cost bracket entirely
- Whether psychosis or severe anxiety is present, which pushes you toward a clinic with psychiatry
- Age — many cannabis admissions are under 25 and need a young-adult programme
The free route, honestly
Free structured psychosocial treatment for cannabis is available through every local drug service, and is the first-line recommendation.
The trade-off is time. Community treatment usually starts within a few weeks, but NHS-funded residential placements commonly involve a three to six month assessment and waiting process. Private admission is typically available within 24–72 hours, and that gap — not clinical quality — is the main reason people pay.
Is cannabis rehab worth the money?
Cannabis treatment is therapy-led, so the honest answer is that a well-run mid-market programme and a luxury one deliver similar clinical content. Paying more buys privacy, setting and staff ratio. If budget is the barrier, the cheapest credible options are a shorter residential stay followed by structured aftercare, or intensive outpatient treatment at £500–£1,250.

Common questions
How much does cannabis rehab cost in the UK?
Cannabis rehab in the UK typically costs £4,000–£7,000 for 28 days at a mid-market private clinic and £9,000–£15,000 at premium providers. Cannabis needs no medical detox, so many people are treated as outpatients for £500–£2,500 instead.
Is cannabis rehab free on the NHS?
Free structured psychosocial treatment for cannabis is available through every local drug service, and is the first-line recommendation.
How much is a cannabis detox on its own?
Cannabis does not require a medical detox, so there is no separate detox fee at most clinics. A short stabilisation stay costs £2,000–£4,500, but treatment for cannabis is therapy-led rather than detox-led.
Does private health insurance cover it?
Bupa, AXA, Aviva and Vitality all cover addiction treatment on many policies, subject to assessment and moratorium terms. Cover usually runs to 28 days at a network clinic. Employer group schemes are the most common route in.
Can I pay monthly?
Some private clinics offer staged payments or third-party medical finance, typically over 12–24 months. It is not universal, so ask before you accept an admission date and check the total cost including interest.
Why do quotes vary so much between clinics?
The biggest drivers are length of stay, whether a medically supervised detox is included, room type and region. Outpatient therapy is often clinically appropriate, which changes the cost bracket entirely.
