Abstract
Drugs derived from amphetamine, methamphetamine and their methylenedioxy- analogues, although being sold as plant food or bath salts, are being used as legal alternatives to scheduled amphetamine stimulants. These products often contain methylone, mephedrone and methylenedioxypyrovalerone (MDPV)--three amphetamine derivatives shown to have strong pharmacological effects. Four postmortem cases were analyzed for methylone, mephedrone and MDPV, with drug levels quantitated in multiple biological matrices. All four cases had detectable levels of methylone, with heart blood concentrations of 0.740, 0.118, 0.060 and 1.12 mg/L. Analysis of several tissue samples shows that methylone does not sequester in a particular tissue type after death. The average liver-to-blood ratio was 2.68. Two cases also had MDPV present, but insufficient data were collected to formulate a hypothesis on postmortem sequestration or redistribution. Two different extraction methods, as well as analysis of derivatized and underivatized methylone, show that the drug is suitable for analysis in either method. The cases are believed to show one instance of chronic methylone use, with a urine concentration of 38 mg/L.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
