Oк, в уики пише 12-24 часа, аз съм чувал за хора които са чакали 24 часа и пак са влезнали в precipitated withdrawal ...

People switching from other opiates should wait until mild to moderate withdrawal symptoms are encountered. Failure to do so can lead to the rapid onset of intense withdrawal symptoms, known as precipitated withdrawal.[29] For short acting opioids such as codeine, hydrocodone, oxycodone, hydromorphone, pethidine, heroin, and morphine, 12–24 hours from the last dose is generally sufficient. For longer acting opioids such as methadone, 2–3 days from the last dose is needed to prevent precipitated withdrawal.
