The acute effect of Swedish‐style snus on cigarette craving and self‐administration in male and female smokers
Bibliographic record
Abstract
INTRODUCTION: Swedish-style snus (SS) has recently garnered controversy for its proposed use as a smoking cessation aid and/or harm reduction tool. However, to date, little work has been done to evaluate the extent to which SS affects cigarette cravings and smoking behavior under double-blind controlled conditions. METHODS: During four double-blind placebo-controlled randomized sessions, 15 smokers (8 male) administered SS, placebo (nicotine/tobacco-free) snus (PS), a nicotine-containing lozenge (NL), or a placebo lozenge (PL) for 30 min and assessed their effects using Visual Analogue Scales and the Brief Questionnaire of Smoking Urges. They could then self-administer their usual brand of cigarettes using a progressive ratio task over the next 60 min. Following the completion of their final session, 11 participants (6 male) ranked each of the products used in the study in terms of their preferences. RESULTS: Relative to the other products, SS was associated with a decreased intention to smoke as well as a delayed onset of cigarette smoking in men but not women. However, SS administration was also associated with increased feelings of frustration and irritability relative to NL and SS was ranked as being the least preferred product used in the study. DISCUSSION: Findings suggest that SS is effective in acutely suppressing craving and smoking in at least some smokers, but that its acceptability may be limited.

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.
