Bath Salts In A Maternity Ward

I thought bath salts were supposed to be non addictive. Isn't that why they are legal in some states. Tell me how something is not addictive if people are smoking it in a maternity ward. Right after they give birth. That is what Carla Murphy did. And right after she smoked it she decided to get naked and punch some nurses. Oh, and kicked them too. When police showed up she tried to punch them and kick them too. Then because this is bath salts story, you know she had to try to eat one of the policemen and tried to bite his face. They never really go for other parts of the body. It is always the face. There is no mention as to what happened to the baby she delivered. I hope the baby is not with her.
