Certified #1 Amazon Be​st Seller

This book is for those of you who are looking for an alternative, either for yourself or for a loved one. And I hope the information inside serves as a support and a hug from me, and all the people I have worked with and practiced for. It is my hope that you will find community in this book and have better information that you can use to make good decisions about your health or help someone you love who is currently struggling. I can’t diagnose you here. I can only educate, and this book is designed to do that. So, the contents of this book are for educational purposes only. Nor can I treat you via this book. What I will do is describe how patients who have visited me in my practice have benefited from the use of medical cannabis, and how medical cannabis works in the body. My job, through this book, is to inform and educate, and let you know that you’re not alone.
