Crack Pipe Sharing in Context: How Sociostructural Factors Shape Risk Practices among Noninjection Drug Users
Bibliographic record
Abstract
With the increasing prevalence of crack use in Canada in the previous decade, crack pipe sharing has emerged as a public health concern, implicated in the transmission of blood- and saliva-borne infections. Drawing on qualitative research with crack users in Victoria, Canada, participants' narratives of sharing pipes demonstrate how risk practices are shaped by social, structural, and environmental factors. Three main themes emerged: sharing pipes with friends and partners; economic motivations for sharing pipes; and the rules and etiquette of crack pipe sharing. Based on these themes we demonstrate that despite conventional views of drug equipment sharing as “bad behavior,” in the lived experience of our participants sharing pipes is a rational and functional activity. Ramifications of these findings are considered in light of future public health programs featuring the dissemination of health information and distribution of safer crack pipe kits.

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.
