Abstract
Recommendations for benzodiazepine (BZD) use suggest durations of no more than a few weeks, but studies report use for months, years, or even decades. This article examines the who (who are long-term users), why (why do they use BZD), what (what are patterns of long-term use) and how (how do they compare to all BZD users). The study population is from the National Population Health Survey in Canada which interviewed respondents four times at two-year intervals, asking about specific drugs use as well as demographic, lifestyle and health-related questions. Long-term BZD use was defined as BZD use for two successive cycles. Four percent of the Canadian population used BZD at any one time, half of whom also reported use in the previous cycle. Benzodiazepine users were more likely to be female, elderly, smokers, to prefer speaking a language other than English, to have insurance coverage for medication, and to have completed high school education. Almost none of these determinants predicted long-term use. Persons reporting BZD use in 2000 had an odds ratio (OR) of 38.6 for also using BZD in 1998, were more likely to use antidepressants (OR=8.5) and suffer from conditions such as poor health, stress, and pain. Most of these determinants had no association with long-term use or if they did at a considerably lower OR. Of the 395 BZD users in 2000, almost 48.4% also used BZD in the previous cycle and 17% in all three previous cycles. Benzodiazepine use in any previous cycle made BZD use in 2000 more likely, with use determined by how recent and the frequency of reported use, culminating in a very high OR of 83.3 for use in all three previous cycles. Continued use for any of the individual BZD tended to be largely for the same BZD. We conclude that: (1) the overriding determinant for BZD use was that of previous use; and (2) long-term use was not determined by the same factors as overall use, which is significant in developing approaches to dealing with long-term BZD use.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
