I was in a similar spot as my father is a high ranking navy officer. There is no way your dad can find out about your mmj use unless you tell him yourself. Dont go to a recruiter for information, he would be more than willing to tell you whatever you need to hear to get you to sign your name on the dotted line..... Your father can not be your caretaker, he can not handle your medicine, grow your medicine.....nothing...He is payed federally and the law is federal...your dad is owned federally. If you live with him or on a military base I would suggest keeping it on the low...Get your own place and you wont have no worries....
