How can I tell if someone is using? Someone close to me has suddenly changed. They have stopped communicating with everyone. Won't answer the phone. I got one vague text after I sent about 30. There hasn't been any argument and I don't think I've done anything to hurt them. My phone tells me my text messages are getting read so I know they are alive. I've asked what is wrong or if I have done something wrong but get no answer.
I'm starting to suspect a drug issue. Either way it's not looking good. Not sure how to approach it.
