@sharehisword Yeah, I think we basically agree - that's what I really meant by "visibly altered." I'll have a drink with dinner while my daughter is awake, but that's pretty much it - I don't want her thinking that I act different sometimes.
@cph My rules around weed are the same as my rules around alcohol:
1. Never get visibly impaired/altered around the kid.
2. Someone always needs to be sober enough to handle an emergency.
Other than that I think it's fine
@chris73
I don't think this needs to be that hard. You don't need to give him a deep understanding of why it's ok - the main thing he needs to understand is that if a word is insulting to a group of people, only the people in that group can say it.
