Abstract
A comparison of cocaine, crack and heroin epidemics documented through participant-observation methods in the United States and Canada reveals dramatically distinct patterns of abuse across differentially vulnerable population groups. Political economic and cultural forces, rather than pharmacology shape the trajectory of drug epidemics. The de facto apartheid of the U.S. inner city and its associated prison industrial complex spawned the massive epidemic of crack smoking in the late 1980s and early 1990s. A contradictory Canadian public policy of police repression combined with centralized, paternalistic social services explains that country's particularly destructive intravenous cocaine epidemic, particularly among its aboriginal and francophone urbanized populations. The United States suffers from the iatrogenic consequences of its failed war on drugs. Heroin and cocaine have never been purer or cheaper despite the massive investment of U.S. public resources in repression at great humanitarian cost.

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.
