ASD doesn't care so long as it isn't on the premises and no one comes to work under the influence. It's legal for adults 21 and older, and would be handled the same way alcohol would be. Someone who get into trouble if they came to work drunk or stoned, or had any product on them or in their desk, but consumption off campus in off hours is no business or interest.

That being said, one would hope those who choose to partake would have some discretion.
