Codral Original contains pseudoepehdreine and codeine. He did get medical advice, from his wife, who is a doctor, not to go flying when he had taken it. He ignored her advice and I'm sure she gave him merry hell for it when he got home. He didn't tell me he had taken it until we were filling in the ATSB report.
And as for ATSB reports, I have found any where I have known the details to be pretty inaccurate. eg I got one for flying over an inbound reporting point at the correct altitude and position but the Poliar aircraft put in a report....even though they were ORBITING
close to it at the inbound altitude, and we were in Class G, I was visual with them etc. The report made me look like the bad guy!
