Query: Toxic and dangerous for little ones

This sand is very unhealthy and can cause Lung Cancer, Tuberculosis, and Kidney Disease, amongst other things. I got this information from the Quikrete website, so they are well aware of the harmful effects of this sand! I'm not sure how these people sleep at night knowing that they are harming thousands of children with their product. Is this legal?
