Can Too Much Weed Make you Sick? The Truth About CHS

Cannabis is a powerful tool for managing nausea, pain, and other chronic symptoms—but what happens when it causes the very problems it's meant to treat? A growing number of heavy cannabis users are showing up in emergency rooms with severe vomiting, abdominal pain, and dehydration. The culprit? A puzzling condition called Cannabis Hyperemesis Syndrome (CHS), which flips everything we thought we knew about weed on its head. In this episode of Grinspoon on Drugs, Dr. Peter Grinspoon, a Harvard trained physician at Mass General Hospital, unpacks the science behind CHS—how it’s diagnosed, why it’s often confused with other conditions, and what it says about cannabis use in today’s high-potency era. Drawing on decades of clinical experience and addiction medicine, Dr. Grinspoon takes a thorough look at this troubling syndrome—and what needs to change in how we talk about cannabis. 🔹 Can cannabis really cause vomiting? 🔹 What’s the difference between CHS and cyclic vomiting syndrome (CVS)? 🔹 Are hot showers part of the diagnosis? 🔹 Is this about THC levels, frequency of use, or something else? 🔹 What can be done—medically, socially, and scientifically? 🎥 Watch now to explore one of the strangest cannabis-related syndromes—and why it’s raising new questions for doctors, patients, and policymakers alike.
