Web Sites Safe For Kids

where can i find site that explain why it is still bad for parents to smoke even outside away from the kids?
my dr said that there are particles that stick to clothes and hair that can still trigger my childs asthma, is this true if so where can i find proof on the web? i want to give it to my daycare and family members that think its safe to smoke outside and come in and cradle my son!!
Here are some great websites for you to check out!
