I have been taking Hydrocodone and Codeine for back problems for several months now and have noticed that the codeine hits my system so much harder with the usual opiate effects. I was wondering if this is a bad sign? I've read that codeine traditionally does not cause a high level of euphoria and hydrocodone does, but doses as little 16mg of codeine as causing much more pronounced effects than 15mg of hydrocodone. I have had legal prescriptions for these amounts the entire time, and I am only taking the codeine since the itchiness of hydrocodone was not outweighed by any analgesic qualities. I guess my question is: is this a sign of danger? or am I just lucky that codeine can cause these effects?
