I've had a personal experience with this, and I'm looking to find other's thoughts on this.
If a student who is at an assistant instructor rank is a drug user, should they be given a chance to clean up, or kicked out? What if they don't improve after their chance to clean up?
I feel that if a student, especially at the assistant instructor level is a drug user, they should get a chance to clean up. However, if they don't, and they can't represent the school's outward beliefs on the subject, that they should not be allowed to participate or teach.
I feel that a black belt is supposed to be a model for all other students. I want to be able to look at any of our school's black belts, and say "I would like to be like him. I am proud to call him a fellow student." However, if they're a drug user, that's not something I can say.
Anyone else have thoughts on this?
