Can I perform an intervention without the guidance of a doctor or a counselor?

I can’t take Preston’s morphine addiction anymore. There’s nothing more painful than seeing your own brother getting addicted to drugs. I only discovered his addiction a couple of days ago. Our mother called me to tell me about it. She didn’t know what to do either. See, I can’t keep an eye on my brother all the time. I’m currently living in New York because of my job while he is still staying with mom in New Jersey. I’m planning to go home this Friday to intervene with his addiction. The problem is, I don’t think I can find a doctor or a counselor to help me with the intervention. Is it okay for me to do it alone or will it make things worse?
