First off remember there is a difference between addiction and dependence. Addiction generally results from taking a med for pleasure reasons, instead of necessity, dependence is when you are in severe pain, or have some other chronic medical condition, and can't function without the use of the meds.
Research also shows that less than 2% off chronic pain sufferers end up addicted to their pain meds, they depend on them, but don't really want to have to take them, and they don't enjoy them, so addiction rarely results. Most of these people would gladly give up the pills and walk away if it were possible.
Your best bet, before assuming an addiction problem, is to speak with your doc about your concerns, they will know best how to assess the risk and address your concerns.
