Abstract
n The majority of the world’s MDMA (‘ecstasy’) continues to be produced in Western Europe, with increases noted in Eastern Europe, South East Asia and Canada. n The majority of MDMA border detections (by number) occurred in the postal stream, whereas the largest proportion (by weight) was detected in sea cargo. n What appears to be a large reduction in the weight of border detections of MDMA is attributable to the high weight of seizures in the previous reporting year. Main Forms Phenethylamines are a group of synthetic drugs which exhibit chemical similarity to amphetamines. As defined in the Australian Bureau of Statistics (ABS) Australian Standard Classification of Drugs of Concern, phenethylamines include 3,4-methylenedioxymethylamphetamine (MDMA) or ‘ecstasy ’ and its derivatives (ABS, 2000). MDMA is a central nervous system stimulant and has both hallucinogenic and ephedrine-like effects (Johnson, Maxwell and Leitnerschmidt, 1997). Although chemically related to amphetamine, MDMA is not a derivative and is produced by a different chemical process. In its base form, MDMA is an oil which can be converted into powder for inclusion into tablets or capsules. MDMA tablets usually feature a symbol or logo from popular culture, such as logos from clothing labels, car manufacturers or other desirable items. Table 6 details common types of phenethylamines used in Australia.

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.
