an interconnection person without further due, please join me in welcoming maia szalavitz to the stage. >> hi everyone, thank you so much, i'm so glad you're all watching. i wish we were all in fact in the stand but that's the greatest place in the world. in case you haven't noticed there are some things keeping us from that. i'm super excited to be here today. were going to be talking today with two totally amazing women who have done such important work. were going to be talking most importantly about one of the innovations in human history that has most saved human lives. were going to be focusing on maia amazing book on doing drugs. could you just hold up a copy of it at the camera if you've got one. i note maia a little bit. but we orbit each other because we write about an overlapping subject. i don't know any writers who work as hard as maia. and do such diligent research in such a spirit of love and compassion. obviously as you have heard. i just want to start, why did you write the book? why is harm reduction so important to you? >> sure. first of all it saved my life personal
