> For those of you that think that a few doses of opioids can't cause addiction, think again. This study found that even after 10 days supply of opioids, 20% of patients had a dependence lasting up to a year.

The study did not find that. The study looked for long-term opioid use, not addiction, and not dependence. Long term use, addiction, and dependence (and tolerance) are all separate things.

Long-term use: simply using a thing consistently for a long time Addiction: compulsive seeking, not noted in any of your links Dependence: something bad happens when use is discontinued Tolerance: more use is required to get the same effects
