Some research points.
1 – The therapeutic doses prescribed for ADHD are not in the risk range unless you already have addiction issues. (All research is a probability, not that an outlier is impossible to find.)
2 – Much of the elevated risk for ADHD’ers with drug addiction appears to be higher for the unmedicated population. As they tend to seek out self-medication. The act of avoiding meds to avoid addiction (again, unless you are in the highest risk groups) may actually increase risk.
