Abstract
Abstract This chapter offers a holistic understanding of the main issues, concerns, and topics that the news media focused on in Canada with regard to the opioid crisis. After reviewing previous studies on news reporting of the opioid crisis, the authors analyze mainstream Canadian news reporting. To obtain the authors’ data, the authors used the Canadian Newsstream database by searching for the term “opioid crisis.” The search yielded 12,029 news items which the authors downloaded, cleaned, and analyzed using a mixed-method approach involving qualitative and digital methods. The authors found that the first article mentioning an “opioid crisis” was from 2012 before politicians framed it as such. Using topic modeling, four major topics emerged in the corpus: supervised consumption and injection sites, overdose deaths, harm reduction, and mental health. In the authors’ study, the authors critically review these topics, offer detailed contextualization, and explore other issues covered in the news media.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
