No offense sir, but it's indicative of character.
Particularly, by your own admission, this was a drug related conviction.

God forgives,
but society shouldn't.

You should not be around children in any position of authority, once convicted
of a drug related offense so serious as to warrant prison time.

This is nothing personal against you...
I'd say the same for anyone w/ similar circumstances.
Nor am I trying to slander your character, you had previously admitted to serving time
in prison.
