Dr.Tod H.Mikuriya once said the West has forgotten more almost everything it once knew about cannabis.As the doctor behind California's medical marijuana movement and California's Prop 215, he saw that many of the medical uses being described by doctors were already found in Arabic treatises or Chinese pharmacopeias.Now, a quarter century of work on the underpinning endocannabinoid system confirm biochem. what's already been described medically.However, one of the most important sources of data are still right here.I've been traveling the States for the last years interviewing patients and practitioners about their use of cannabis for medical reasons.The wealth of patient anecdotes confirm much of what the preclin. works suggests but the most important source of information is in the doctors who have been quietly advising patients about medical marijuana for the last few decades.Some of these physicians go onto write books that explain their hard-earned rules of thump - but many of them keep the information to themselves out of fear or lack of time to sit down and write.They become silos of data that will be lost when they are gone.With a material as variable as cannabis in its effects on humans - always contradictory and a wide range of possible reactions because of people's individual endocannabinoid system - these doctors, underground healers and patient advocates posses a huge storehouse of knowledge that highlights potential avenues for future research as well as practical considerations for right now.We'll share the highlights distilled from hundreds of interviews into what the medical use of cannabis looks like in the real world - especially for elderly patients.
