In this episode, I risk my professional reputation once again.  Mac and I bond over ayahuasca and MDMA.  She steps up to the mic to talk about her book Irritable Hearts (about her own struggle with PTSD after an assault while on a foreign assignment) and her recent expose for Rolling Stone magazine -- apparently there's an underground network of therapists and doctors who treat patients with hallucinogens, not to mention studies taking place at top American universities on the use of psychedelics to treat addiction, PTSD and depression.
