Addiction and dependency are two different things.
Addiction is the "thirst", the cravings for a drug/behavior. Addiction can be a form of psychosis. Addiction by itself never kills anyone but drives people to behaviors that can be fatal, such as ignoring the dangers of acquiring the drug.
Dependency is the adjustment of the patient's body to the drug, requiring both higher doses to attain the same result and a maladjusted state when the drug is not taken. Withdrawal is what happens when a person that is dependent on a drug does not get their drug, and in the case of Xanax, could be fatal.
Addiction can cause dependency, and dependency can cause addiction, but they are not the same.
Imo it is just semantics. I, personally, prefer to just separate those as "physical addiction/dependency" vs "psychological addiction/dependency". For example, xanax would qualify as physical, while cannabis as psychological.
P.S. Not trying to say that one can't use cannabis without being addicted, it is absolutely possible. But psychological dependence potential is there. Realistically, almost anything can be psychologically addicting imo
