<human>: Can you summarize the given text in a few sentences?

I work for an organization that runs summer/winter camps for kids and adults with special needs (ranging from ADHD to full-care disabilities). This past week I was a counselor in a cabin of boys. One of the boys (10 years old) was constantly coughing, and needed a special vibrating vest therapy each day to help him breathe, and his throat and chest looked strained and distended (forgive me for not knowing the technical terms, but he has a diagnosis of some sort of lung disease).

Yesterday his parents came to pick him up. I grabbed his bags and was walking him out to his car. His parents got out and a rolling wave of nicotine came pouring out of their car. Windows rolled up. 

I was fighting back angry tears as we begrudgingly handed the kid back over to the parents who each had a lit cigarette hanging from their lips. He sat down in the back seat, and started hacking up a lung before we even got a chance to close the car door.

How on earth can this be tolerated? Is there anything I can do? Legal recourse? Agencies I could call?

I don't know if their smoking caused his disease, but it clearly isn't helping. Is this abuse? Neglect? Some grey area? I just wish there was something I could do.
<bot>: A 10 year old boy I know with a lung disease is living with chain-smoking parents. Anything I can do?
