The duration of opiate withdrawal can vary depending on the individual, the severity of the addiction, and the type of opiates that were being used. Generally, acute withdrawal symptoms peak within the first few days of discontinuing opiates and may last for up to two weeks. However, some individuals may experience post-acute withdrawal symptoms (PAWS), which can last for several months. It’s important to seek medical assistance when withdrawing from opiates to manage symptoms and prevent complications.
