Brings a whole new meaning to "show and tell", doesn't it?
I can appreciate your concern, regardless, but I'm wondering this--is Illinois one of those states that treats possession of marijuana under a certain # of ounces (usually referred as for "personal use") just a minor offense, a fine only? Is that why the police aren't taking any action?
I would still request a written report from the police and DCFS about the incident for possible future use if his behavior worsens or you have other indications it is affecting your children.
Does he grow his own? I'm not trying to be funny now, I'm asking for a serious reason. Although it still doesn't set a good example for the children since it is an illegal drug. But, if he is growing a little for his own use, I wouldn't feel the children are in any more danger than if Dad has a few beers. But, if he is buying from a dealer, somewhere along the line, a criminal element is involved and that would worry me more as far as children are concerned.
If you could find out more about how he obtains it, perhaps it might make a difference in how DCFS views it as a risk to the children.
