Quote From: arbeeteezI am the mother of three children, 17,15 & 12. While the youngest lives with me, the older two live with thier father. he allows them to smoke pot in the house (whether he is home or not). I'm afraid my youngest will want to join them and thier friends. Calling child protective services seems to be my only option, but I'm not sure that will help our relationship. When I told my ex I planned on drug testing my youngest when she came home, he told her to drink lots of water to flush her system out. Any suggestions 
Call CPS.... file a complaint... and you kids will be interviewed.. by a CPS agent... they will either lie, or cop a 'tude and say "no big deal"... lets hope for the latter.
Yeah, your going to be hated... despised... called a nark... but deep down.. they will know they are protected and loved.... and when they are 25 or 30.. they're going to say "Mom, you were right" .
I know... my ex attacked my 6 year old... I believed him when no else wanted to because it was too hard.. too sticky, too "out of character" and it was my 6 year old word against his fathers.. who of course.. Minimized the incident to a tap on the head and name call.. HA ! No one would believe my child. and they were just too scared, or considered it too upsetting and painful to do anything about it. My son knows I love him, I protect him and I will go to the wall for him... I am his MOM...and boy... you better believe my ex walks on eggshells...and for good reason now.
No one hurts my son and gets away with it.
Defend your children.
