I imagine it varies depending on the drug, the patient and the dosage. I was recently on heavy doses of morphine for 10 days and was left unable to eat normally for 4 months afterward, so it can happen quite quick.
But the point is, whether you're addicted or not, you cannot stop taking the drug. If you stop alcohol or smoking you might experience light to severe withdrawal symptoms depending on your level of use, even hospitalization. With opioids you will experiences months of crippling pain and inability to eat normally with the only remedy being more opioids. And you might not even know it's the opioids doing it because the doctors give that garbage out like candy and don't warn you about these side effects.
