It varies greatly between people and also depends on how long you've been using opioids. A lucky young person who's never really abused drugs before could use a good 20mg-40mg dose of oxycodone daily for maybe 7 days or more, and experience only minimal symptoms after discontinuation. But someone who's been doing opioids for years and has a "relapse" may feel shitty after even 1 usage of their favourite opioid.
The regular and habitual users of opioids eventually do build a psychological addiction. Just like any other pleasurable activity, if you like it you're going to want to repeat it in future.
These kinds of threads are asked all the time. Nobody can tell you when you'll get addicted or dependent. It depends greatly on your personality, environment, supply of drugs, body type, genetics, stress, and other things.
