Another winner of a study...

At first glance this one seems obvious. "Child Abuse Linked to Meth Use, Doctor Says"

I'd figure if you're hopped up on crank you might be more likely beat on your kids.

BUT,

Reading the article, this doctor is not concerned with stoned parents abusing their kids. No. He's concerned about the children of the cooks that produce Ice in their homes. Exposure to those chemicals might be harmful and could lead to asthma.

And Arkansas already has a law forcing ephedrine and pseudo-ephedrine containing OTC drugs to be locked up in stores. I guess once they lock the stuff up in NY, enough additional cooks will show upto require the DCS to start tracking the cooks' children for signs of exposure.
