Pharmacists and Natural Health Products: A systematic analysis of professional responsibilities in Canada
Bibliographic record
Abstract
PURPOSE: Natural health products (natural health products) such as herbs, vitamins and homeopathic medicines are widely available in Canadian pharmacies. The purpose of this paper was to conduct a systematic analysis of Canadian pharmacy policies and guidelines to explore pharmacists' professional responsibilities with respect to natural health products. METHODS: Legislation, codes of ethics, standards of practice and guidance documents that apply to the practice of pharmacy in each Canadian jurisdiction were systematically collected and examined to identify if, and how, these instruments establish professional duties in regard to natural health products. RESULTS: The majority of Canadian jurisdictions now include some explicit reference to natural health products in standards of practice policy or guideline documents. Often natural health products are simply assumed to be included in the over-the-counter (OTC) product category and thus professional responsibilities for OTCs are relevant for natural health products. A minority of provinces have specific policies on natural health products, herbals or homeopathy. In addition, the National Association of Pharmacy Regulatory Authorities' Model Standards of Practice specifically refers to natural health products. Most policy documents indicate that pharmacists should inquire about natural health product use when counselling patients and, when asked, should provide accurate information regarding the efficacy, toxicity, side effects or interactions of natural health products. Public messaging also indicates that pharmacists are knowledgeable professionals who can provide evidence-based information about natural health products. CONCLUSIONS: Explicit policies or guidelines regarding pharmacists' professional responsibilities with respect to natural health products currently exist in the majority of Canadian jurisdictions.

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.
