As seen online:
“CHS usually starts after years of using marijuana many times a week. Initial symptoms are feeling sick to the stomach, belly pain and the feeling like you may throw up. A lot of people can still eat without throwing up. After about 10-12 years of chronic marijuana use, patients begin to have a strong feeling of sickness, throwing up, and belly pain. This is normally when people go see a doctor to find out what is causing these problems. They start to feel better when they stop using marijuana but can feel bad if they use it again. ”
