Know the important distinction between drug dependence and addiction (substance use disorder).
“It is common for people to conflate physical dependence and addiction, believing they are synonymous.
According to the FDA:
Physical dependence is not synonymous with addiction; a patient may be physically dependent on a drug without having an addiction to the drug. Tolerance, physical dependence, and withdrawal are all expected biological phenomena that are the consequences of chronic treatment with certain drugs. These phenomena by themselves do not indicate a state of addiction.
Drug addiction is a cluster of behavioral, cognitive, and physiological phenomena that may include a strong desire to take the drug, difficulties in controlling drug use (e.g., continuing drug use despite harmful consequences, giving a higher priority to drug use than other activities and obligations), and possible tolerance or physical dependence.”
