Opioid withdrawal occurs when individuals abruptly reduce or cease their opioid use after prolonged dependency. The symptoms of withdrawal can range from mild to severe and typically manifest within hours to days after the last opioid intake.

Many people who use fentanyl are reporting precipitated withdrawal reactions when they take Suboxone, even if they follow the administration instructions exactly (waiting at least 24 hours AND waiting for the onset of opioid withdrawal symptoms).

Opioid withdrawal can be miserable and some people would do anything to avoid that misery. Anesthesia Assisted Rapid Opiate Detoxification (AAROD) was created as a technique to ameliorate the pain of withdrawal.
