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.
