Would the GFL have any suggestions of a holistic approach to mental health/addiction as alternatives to pharaceuticals?

I am very blessed to not have this, but I've been dealing with loved ones with a real addiction problem.  I've noticed in the past that certain people have this.  While I am thankful I do not have this, I am powerless watching others suffer and they can't help it.   Would the GFL have, perhaps, an Edgar Cayce style holistic remedy?   If they would, it could help so many people.  They just perhaps have to break it down for certain types of addictions/personalities/diagnoses.  This has the potential to be life changing for so many people. Thank you! <3
