It took me a good year of off and on use/misuse to get a physical dependency to opiates...to the best of my knowledge they try not ever to prescribe more than 2 weeks of pain pills for non chronic conditions as that seems to be the point dependency starts to creep in...they are a handy tool for pain if taken as prescribed...I think you only have to worry if you find yourself out and making an effort to get more...if that happens, stop dead in your tracks and run the other direction...mine started after a car accident...my ex gave me a couple percs and a dr gave me vicodin and so the saga began....but physical dependency wasn't til I was using every day for a good stretch
