Concerns with family smokers & my infant while on vacation

I would be more concerned about leaving my 6.5 month old with people ,family or not, that are so stupid that they somehow think that taking dryed leaves, wraping them in paper, lighting it on fire then breathing the fumes is OK to do, and then thinking its OK to do near a baby.
SMOKERS = STUPID , IRRISPONSABLE , BRAIN DAMAGED IDIOTS!!!!
