Getting through withdrawal safely

If you're planning a detox, a 10-minute call with our referral team rules out routes that aren't safe for your dose and history.

Clearpath UK Rehab is principally a referral service: we do not own, operate or provide treatment at any clinic. We are funded by fees paid to us by partner rehabilitation services when a person we refer takes up a placement with them. Free NHS and charity support is available without going through us — see the free help options on this page.

Common questions

Are these timelines exact?▾

No. Withdrawal timelines vary with dose, duration, individual physiology and any co-occurring conditions. The days shown are typical ranges seen in UK clinical settings — use as a rough map, not a schedule.

Is home detox safe for all these substances?▾

No. Home detox is safe for cannabis, cocaine and mild-to-moderate alcohol dependence. It is dangerous for severe alcohol dependence, benzodiazepines and opioids without medical supervision.

What is PAWS?▾

Post-acute withdrawal syndrome — the low mood, sleep disruption, anxiety and cravings that can persist for weeks to months after acute withdrawal ends. Most common with alcohol, benzos, opioids and stimulants.
