Abstract
Background: 4-Fluoroethylphenidate (4F-EPH) is a psychoactive substance, sold primarily over the Internet as a `research chemical'. Recreational and `functional' use of this drug has been reported by online user fora. Scientifically-based data on the pharmacological, physiological, psychopharmacological, toxicological, and epidemiological characteristics of this molecule is non-existent. The aim of this paper is to remedy this situation. Methods: Recent literature (including 'grey') was searched to update what is known about 4F-EPH, especially its toxicity. This was supplemented by netnographic examinations of internet sites. Results: The resultant information is presented, including details of the first reported death involving 4F-EPH use in 2016. There are no international controls imposed on 4F-EPH. However, it has been made a controlled drug in several European countries, including the United Kingdom since 31 May 2017, as well as Canada. Conclusions: It is vital that any other cases, including non-fatal overdoses, are documented so that a firmer scientific evidence-base can be established for this molecule. This will then help inform clinical practice.

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
