I know my 16 year old son is using marijuana. he doesn't deny it. He was going to school regularly and doing OK. A couple of days ago he refused to go to school. We disconnected his internet and phone services. He left home. Came home past his curfew time. This morning he took an open bottle of vodka from the cabinet and told me that he is going to sell it, if I don't pay him five dollars. I ignored him. He left home. I don't think he took the bottle...however, I can't find it. I am not sure what else to do and for how long my husband I should continue the "mouse and cat" game. Please advise.
