PHYSICAL DEPENDENCE

Definition:
    Physical dependence is the physiological adaptation of the body to the presence of an opioid. It is defined by the development of withdrawal symptoms when opioids are discontinued, when the dose is reduced abruptly or when an antagonist (e.g., naloxone) or an agonist-antagonist (e.g., pentazocine) is administered.[6]

Clinical relevance
    Physical dependence is a normal and expected response to continuous opioid therapy. Physical dependence may occur within a few days of dosing with opioids, although it varies among patients. Physical dependence (indicated by withdrawal symptoms) does not mean that the patient is addicted.[6]

    Health care workers should advise patients to take their pain medication as directed, and that withdrawal symptoms may occur if they reduce their dose or stop taking the medication.[7] Symptoms of withdrawal may include agitation, insomnia, diarrhea, sweating, and rapid heart beat. If the source of pain is successfully treated or removed, physical dependence is easily treated by gradually decreasing the opioid dose, e.g., reducing the daily dose by 10 to 25 percent every 2 days. When a daily dose of 10-15 mg of parenteral morphine (or its equivalent) is reached, maintain that dose for 2 days, then discontinue.

    The development of physical dependence should not limit analgesic therapy. Antagonists and agonist-antagonists in the patient who is physically dependent should be strictly avoided because their use will neutralize the analgesic effect and cause a withdrawal syndrome.

Misconceptions:

    * Physical dependence is frequently equated mistakenly with addiction. It is incorrect to use the term 'physical dependence' (a physiological state) to describe addiction (a dysfunctional  psychological and behavioral syndrome).[1]

    * Patients who express concern about physical dependence should be given correct information and reassured. Example: "Do not to stop taking your medication abruptly or you will have symptoms of withdrawal. If you no longer need opioids for pain relief (for example after a course of radiotherapy), your physician can gradually decrease your dose over several days."

ADDICTION

Definition:
    While tolerance and physical dependence are physical changes in the body, addiction is defined by aberrant changes in behavior. Addiction is compulsive use of drugs for nonmedical reasons; it is characterized by a craving for mood altering drug effects, not pain relief.[8] Addiction means dysfunctional behavior, in sharp contrast to the improved function and quality of life that result from pain relief. Aberrant behaviors which indicate addiction may include: denial of drug use; lying; forgery of prescriptions; theft of drugs from other patients or family members; selling and buying drugs on the street; using prescribed drugs to get "high."[8]

I think that the pharm industry has succeeded in having drs prscribe to a lot of people what is heroin in a pill and what you have printed above is how they did it.  I think the only difference between addiction and dependance is semantics and time. Will your dr keep incresing your pills as your tolernce increases?  Pharma has convinced drs that tolerance doesn't occur if opiates are taken for pain, but that hasn't been my personal and professional experience, though some might have other experience.
