34 The Medical Panel's finding that the applicant was suffering from "a substance abuse disorder, relevant to the claimed back injury" was the final example of the alleged failure to take into account a relevant consideration. Mr O'Loghlen submitted that, in the Medical Panel's reasons, the only indication of what constituted that substance abuse disorder was the reference to the applicant telling the Panel that he was "having regular injections for pain". In the medical reports before the Medical Panel, this had been described in some detail. In a report dated 28 July 1999, Mr Hayes, an orthopaedic surgeon, said that for the past three years the applicant had been seeing Dr Luscombe every month for a prescription for a self-administered 100 ml of Pethidine, eight a month as prescribed by another doctor, and otherwise had been taking Panadeine Forte, four to eight a day. Mr Hayes said that the applicant consumed a good deal of Pethidine which was "a notorious narcotic drug of addition". Mr Weaver, in a report dated 11 October 2004, said that the applicant continued to self-inject Pethidine on a very regular basis, and that he was obliged to use up to eight scripts per month in this regard. Mr Weaver stated that long term use of Pethidine could clearly be expected to have "some addictive effects" for the applicant. Mr Perera, in a report dated 16 December 2005, said that the applicant's medication consisted of Pethidine, for which he usually had about eight scripts per month, depending on his pain. The applicant usually had two doses of 300 mgs at a time and also used Normison. Finally, Mr Phillips, in a report dated 17 March 2006, said that the applicant had forty Pethidine injections a month. Sometimes he was given them and sometimes he injected himself. On some days, he had no injections but on other days, it could be two or three. Mr Phillips stated that the applicant had become "dependent on Pethidine, one might say addicted".
