“Many people, including doctors, are confused about the difference between physical opioid dependence and opioid addiction.
The presence of physical withdrawal symptoms alone is NOT the same thing as opioid addiction.
For addiction to exist, the person taking opioids must have psychological manifestations. Such a person suffers from the obsession and compulsion to use more opioids, even knowing bad things happen with opioid use. A person with addiction neglects other important parts of life in order to focus on the use of opioids. She may use the drug in ways it’s not meant to be use – injecting, snorting, or chewing for faster onset. She may start using opioids to treat negative emotion, and mix them with other drugs for different effects. She may use opioids even when not in pain, for the effect the drug has on her.”
