I am a legal medical marijuana user. My two oldest kids are in their grandparents' custody (long story but not marijuana-related). It has come to their attention that I have my medical marijuana license and they are now refusing to allow me any sort of unsupervised visitation, even though I have a court order granting me 1 weekend visit a month. How do I defend myself and my use? I am accused of using in front of my children, which is untrue. How to I show that my use is ok?? PLEASE HELP!!!
