A deficiency in endocannabinoid function can lead to a condition known as Clinical Endocannabinoid Deficiency (CECD). CECD has been linked to chronic conditions such as Migraine, Fibromyalgia, and Irritable Bowel Syndrome (IBS). Symptoms of ECS deficiency may include chronic pain, mood disorders, and digestive issues, indicating that the ECS is not functioning optimally.
