"addiction" is not equivalent to "dependence", nor does one imply the other. pain management patients are typically dependent on opioids; they would have severe withdrawal if they abruptly stopped their regimen. but they don't necessarily have the compulsive/obsessive behavior of addicts. there are also drugs people get addicted to that don't have much or any associated withdrawal symptoms. people don't get withdrawal from gambling, but they can surely be as addicted as opioid users.
I've seen several comments like this recently. addiction seems an odd thing to gatekeep. the only "requirements" for addiction are impairment of control related to particular behaviors/substances, preoccupation with said behavior/substance, and continued use/behavior despite consequences.
