What I see with the chart is a growing aging pilot population. Not sure why the mention of cholesterol lowering drugs since there is no FAA medical standard for cholesterol. I’ve been on blood pressure meds for 30 years, all approved by the FAA. So are the drugs mentioned in the chart legal for that pilot by the FAA, or did the NTSB just lump all drugs found into the chart data? Not sure what the NTSB wants here. The Canadians have set 30 days as the waiting period to fly after consuming marijuana. I doubt there would be any support for drug testing of pilots not flying for air carriers. Considering that only .15% of pilots involved in air carrier flying test positive for illegal drugs, one has to wonder what benefit drug testing pt 91 or private pilots would be, and who would get stuck paying for that.
