Question

opioid users who quit and get clean are at a higher risk for overdosing if they decide to use again. why is this? they ingest a typical dosage from before they stopped -- a dosage which is now far too high. because they need more of the drug to get the same high. rewatch

Explanation:

When opioid - users quit, their bodies adjust to the absence of the drug and their tolerance decreases. If they then take the same dosage as before they quit, it is now a much higher amount relative to their new, lower tolerance level, increasing the risk of overdose.

Answer:

They ingest a typical dosage from before they stopped -- a dosage which is now far too high.
