Well they know I'm not opiate naive, I have had 14-15 major surgeries and have been on opiates and opioids under medical supervision for considerably long periods of time, last time I was in hospital I was being given 50mg oxycodone orally,400mg Demerol im, 200mg tramadol im daily...I've been on all sorts of pain killers prescribed by the people in question over the last 2 years I.e fentanyl, buprenorphine, morphine and generally a combination of different ones at the same time. I've been in hospital on opiates for so long that they put me on methadone leaving the hospital on 2 occasions, so they know I have an opiate tolerance to begin with and I plan on being clean from codeine at least 2 months prior to surgery, I'm just wondering is it absolutely necessary to tell them I've used opiates for recreational purposes because this might screw me when it comes to needing pain meds in the future... Codeine is the only opiate I've used recreationally and not under medical supervision
