Writing in 2019, Crace described his "cold turkey" rehabilitation from heroin addiction 32 years previously.[6][7]
In July 2019, The Guardian retracted statements by Crace implying that right-wing political journalist Isabel Oakeshott had obtained confidential files by having sex with Nigel Farage and Arron Banks. His article included the claim that Oakeshott only got confidential emails if Farage and Banks "slips it to her". Following the threat of legal action by Oakeshott, the text was amended to: "leave it conveniently tucked under her pillow". This second revision was then removed, with the final version stating: "if he or Arron Banks leave it conveniently to one side for her". Oakeshott stated: "It gives me great pleasure to teach John Crace and The Guardian a little lesson about casually slurring women whose politics they dislike".[8]
On 11 March 2024, Crace posted on his X/Twitter account that he had suffered a heart attack and was receiving treatment in St George's Hospital, London. He wrote an article in The Guardian on 21 March 2024, giving more details.[9]
Crace collects British stamps and has written columns for Stamp Magazine.[10]
