Marihuana legalization and its effects on consumption and teenagers' perception
Bibliographic record
Abstract
The purpose of this study is to test if the legalization of recreational marihuana implies an increase in the number of new consumers and if, at the same time, the teenager's perception of the substance is affected by the measure. A historical review of cannabis focusing on its uses and legal status throughout the time was performed in order to have a solid background of the topic. Then, why and how Uruguay and Canada recently legalized the plant was analysed, pointing out the differences between the two approaches: socialist vs capitalist. The case of the United States is also considered, explaining the current legal situation of the substance in the country. Finally, using data from the National Survey on Drug Use and Health (NSDUH) a quantitative analysis was conducted in the United States. It was concluded that the legalization of recreational marihuana potentially implies a positive increase in the number of new consumers of the drug and, on the other side, that the perception of teenagers regarding the drug is not likely to be affected by the new legal status of the plant.

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.
