I was charged for marijuana possession (misdemeanor) over 10 years ago in the state of California. The small amount I had is actually legal now, and California has made efforts to dismiss these prior convictions now that it's legal. My case has been sealed and destroyed, and the county court can no longer even see the charge at all. I am in the beginning stages of flight training, and just completed my first class medical. My AME is aware of this previous charge, and he recommended I answer "no" to question 18w on the medical where it asks about any non traffic misdemeanor convictions since the case is sealed. He was not worried about the charge in the slightest since it's so old and is now legal, and I agree that the charge itself would likely not keep me from becoming a pilot. But now that the medical has already been passed and submitted, I'm starting to worry that "no" was the wrong answer to that question and it's going to come back to haunt me. Even though the case has been sealed, I imagine the FAA can still see that charge and may think I intentionally lied in my answer to cover it up. I'm more worried about a falsification issue now. I had also already responded "yes" in the IACRA form where it asks about being convicted of a drug crime because at that point, the case was not yet sealed. This discrepancy may also raise a red flag. I have already been granted a temporary license but haven't gotten the real card in the mail yet. The AME has records of my case on file and reiterated that he's not worried, but what do you recommend the best course of action to be? Is it best to just correct this on my next medical in six months and include a note about why we said "no" to 18w the first time? Or reach out to the FAA to explain the situation before they find it and think I was intentionally lying (would I do this or the AME?)... or not raise attention to it? I am just assuming the worst and am nervous they will revoke my license completely — would like to avoid this, of course. Thanks for any and all advice!
