I am a PHYSICIAN, an MD and and I AM IN RECOVERY. I bought BOTH text and audio so I read and listened to both! This is an outstanding work by David Sheff! Clean is an extensively researched and very compelling body of important information! A strong argument for an end to the criminalization of America’s drug problem. I could not agree more! NARRATOR IS WRONG FOR THE SUBJECT MATTER! He sounds sardonic, sarcastic and cynical like he is delivering a monologue in a stand-up comedy routine ! The narrator nearly ruined the impact on me! The information is so very important I hated to hear it delivered badly! MR SHEFF I WANT TO NARRATE YOUR BOOK FOR YOU ...I could do a far better job!
