I do know what state you are in but in California, mandated reporters report known or suspected abuse or neglect. This child may be neglected if there is no physical abuse. To ask a relative stranger to take a 5-year-old to a pool
sounds neglectful. You do not have to "prove" anything, CPS will make a determination if it warrants investigation. Trust your gut feelings. I am an RN specializing in behavioral health and have done more than my fair share of APS & CPS Reports. In my present job, I work with social workers & RN's making recommendations for their follow-up on complex medical, psychiatric & chemical dependency cases and if this were a case I eas reviewing, I would encourage the staff to err on the side of caution. Our most vulnerable need us to look out for them when no one else is. Reports can also be made anonymously if you are fearful of repercussions from the neighbors.

I hope this is helpful and am aware others may disagree with me. I would do it if I were in your shoes.

PS: my response has nothing to do with the cigarette smoking though it is unheathful for the children. We are not yet at the point parents are penalized for smoking & no I do not smoke.

Good luck, the child (children) are lucky to have you as their neighbor.
