Addiction vs Physical Dependence - Important Distinction

Addiction is a nasty word. It is particularly suitable for those who rely on painkillers and analgesics. The definition of addiction varies, but most addicts are classified as negative categories. Some right-wing radio hosts, Rush Limbaugh, Courtney Love of singers and actors, and analgesic addicts including "Friends" star Matthew Perry and other celebrities are famous for becoming dependents Survive in the life that some people only need to live everyday life. 53-year-old Judy is a high school teacher in Williamsburg, Virginia.

There is an important difference between the use of heroin and the use of heroin. Addiction is characterized by frequent use, improved tolerability, and physical dependence. Drug users use at least one dose of heroin (or similar) each day, and his intake increases over time. However, not all 94 heroin users depend heavily on drugs, but most of them are used for 2 to 3 years. On the other hand, only 43% of people take heroin (T. Ib) 2 more than once a day at least once. These are the only things that can be considered to be addictive. The remaining time of the week is about two to three times or less, and even if some of them are injected directly into the veins, many of them are still not addictive to this extent. In addition, only about half (54%) of the drug was administered intravenously, most people chewed the nose (28%) and a small number (7%) were injected subcutaneously (T. Ia)

Some physicians have misunderstood the important differences between physical dependence and addiction for a long time. Repeated administration of any opioid almost inevitably leads to the development of tolerance and physical dependence. These predictable phenomena reflect inverse adaptation of opioid receptors and their intracellular signaling cascades 29. Short-term results of these short-term opioid administrations quickly disappear after opioid withdrawal (ie days). Depending on the duration of the opioid, within a few weeks, exposure, opioid and dose). Conversely, only a small proportion of patients exposed to opioids will develop intoxication. Poisoning usually progresses slowly after exposure for months, but once intoxication develops it usually does not stop the opioid, it is another normally, usually chronic condition that is not properly treated. High risk of recurrence for years

Unlike tolerance and physical dependence, addiction is not a predictable outcome of opioid prescriptions. Addiction occurs even for a small proportion of people exposed to opioids, even already vulnerable people (Table 3). Several versions of previous medical literature and psychiatric diagnostic and statistical guidance (DSM) have roles of tolerance and physical dependence in the definition of addiction or roles equivalent to these processes (DSM-III and DSM- IV) too much. However, recent studies have suggested that the molecular mechanism of dependence is different from the mechanism responsible for tolerance and physical dependence.
