Sorry if I'm overstepping here, because I don't have experience of narcotic addiction, but is it not kind of weird for Jack to join Tattle to tell us off for even mentioning using heroin in the same sentence as her, but then splashing all over Twitter that she takes opioids so regularly that they are having absolutely no effect? And exhibiting what some doctors would define as drug-seeking behaviour?
Something sitting very strangely with me, there (outside of, y'know, *gestures wildly at everything else Jack ever does*).
