Honestly not sure. However, I wouldn't try to stress about it too much. If it was something that happened while you were young and won't prevent you from receiving your medical license, just own up to it and explain that you've learned from it.
I had a public urination I listed. Although I wasn't arrested and I'm 99% sure it's not on my record anymore, I disclosed it. I've actually had schools already tell me that it won't affect my app and that they appreciate my honesty.
Good luck and roll tribe.
