Heroin use and barriers to treatment in street-involved youth
Bibliographic record
Abstract
High rates of drug use and risk behaviours have been reported among street involved youth. The present study examined the drug use and risk behaviours in adolescent heroin users, assessed motivation for treatment, and identified barriers to accessing treatment. Forty-nine heroin-using adolescents from four youth community agencies in Toronto were interviewed. Participants reported having used, on average, four different substances in the previous month. Seventy-nine percent had engaged in injection drug use and of these, 58% had shared their injecting equipment. Significant gender differences were found in the prevalence of psychiatric and family problems, the type of drug programs used, and perceived barriers to treatment. Although more than half of the sample had sought treatment for their substance use problems and were knowledgeable about the treatment options available, many believed factors such as lack of housing, finances, and contact with drug-using acquaintances would hamper their rehabilitation. Treatment programs for these youth should include the assessment and treatment of comorbid psychiatric disorders, and the provision of comprehensive services including ‘safe’ housing, vocational guidance and financial supports.

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.
