My Codeine problem by UnlikelyAddictHi Needachat, I can provide some reassurance on the physical side. Opiates are relatively safe for the body if you say within safe doses - they rarely cause long term damage unless mixed with something else. For most people the physical damage comes from ibruprofen or paracetamol that are in the tablets they take, or cosumption of alcohol. A lot of addiction websites, will state liver damage, kidney damage etc - but they are generic descriptions. Respiratory problems are not going to be a problem for you because of codeine withdrawal in my opinion. Respiratory depression is associated with codeine overdose, or cross contamination with other depressants like benzodiazepines (diazepam most commonly) and alcohol. If you are not of codeine right now, well done, try to keep it that way and get your life back.
