You are perfectly entitled to smoke a lawful substance in your own home.
Some people just want to live in a world where everything is their own way and unfortunately they have to make compromises to accommodate others.
Don't engage with people who enjoy complaining. They are never happy unless they are offended about something.
Can I clarify anything for you?
Not your problem.
Contrary to the belief of parents, actually everybody else is not responsible for the care of their children.
If their child has a respiratory condition then best they bear the cost of moving to the country.
Leaving the rest of us to lead a normal life.
Free from the screaming of their children.
