Experience with the Synthetic Cannabinoid Nabilone in Chronic Noncancer Pain
Bibliographic record
Abstract
Chronic noncancer pain includes a heterogeneous group of disorders and is often refractory to treatment. Cannabis products have historically been used for chronic pain and are attracting renewed pharmaceutical interest. Nabilone is a synthetic cannabinoid licensed in Canada for the treatment of severe nausea and vomiting associated with cancer chemotherapy. We have used nabilone off-label for the treatment of chronic noncancer pain since 1999. In this article, we review our clinical experience of 20 adult patients with chronic noncancer pain who had been treated with nabilone and followed up for an average of 1.5 years. Prior to nabilone therapy, patients had used a wide range of therapies, including 11 who had used cannabis. Fifteen patients reported subjective overall improvement with nabilone, and nine reported reduced pain intensity. Beneficial effects on sleep and nausea were the main reasons for continuing use. Intolerable side effects were experienced in three patients (palpitations, urinary retention, dry mouth). Nabilone may be a useful addition to pain management and should be further evaluated in randomized controlled trials.

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.
