In this episode Bryan Johnson, Dr. Mike Mallon, and Kate Tolo discuss the health and longevity implications of various drugs. They begin with a vivid description of how ketamine scrambles brain network activity, supported by real‑time fNIRS data from Kernel that shows a temporary “therapeutic window” of altered connectivity lasting a few days. They cite a small clinical study where six ketamine infusions reduced participants’ epigenetic/biological age by 1‑2 years, suggesting possible longevity benefits. The conversation then shifts to the risks of stimulants, especially cocaine, which they note increases cardiovascular disease risk and can cut 10‑12 years off life expectancy. They warn about widespread fentanyl contamination of street drugs and recommend a “don’t‑die kit” (fentanyl test strips and naloxone nasal spray) for harm reduction. Social norms around discussing drug use and even sexual practices (analingus) are explored, highlighting differing comfort levels among the hosts. They review ketamine’s safety profile, modest addiction potential, and bladder concerns, and contrast it with classic serotonergic psychedelics. An animal study is described where co‑administration of a DUSP6 inhibitor (BCI) boosts ERK signaling, extending ketamine’s therapeutic window from days to weeks, prompting ideas for human protocols that combine ketamine with learning tasks, mitochondrial or methylation panels, and other biomarkers. The episode concludes with a summary: cocaine is detrimental to longevity, harm‑reduction tools are essential, and ketamine shows promise for mental‑health and possible age‑reversal effects, especially if its therapeutic window can be prolonged.
