If a mother is allowing her 15 and 16 year old kids to smoke marijuana in their home (and you are 100% sure it is true) will CPS do anything at all? I have never used mj, but I do believe it is of course not as harmful as other drugs. But I do think it is the gateway drug to others and that is what I'm concerned about. If the mom is a relatively okay mom - just lets her kids smoke marijuana - but does NOT abuse them emotionally, physically or anything will CPS do anything at all?????
