Treatment

If you have had severe vomiting, you might need to stay in the hospital for a short time. There are a few different treatment options to provide relief from CHS symptoms but individual results may vary:

• IV (intravenous) fluid replacement for dehydration
• Frequent hot showers provides relief to some but not all CHS patients
• A small amount of capsaicin cream applied on to the abdomen helps temporarily relieve symptoms for some but not all CHS patients. Capsaicin cream is a cayenne pepper based cream and creates a burning sensation that may be painful. If the burn becomes uncomfortable, apply milk to relieve the burning sensation. Do NOT apply water to the skin and do NOT take a bath when the cream is applied to the skin. 
• Running. A very small percent of patients find relief by engaging in physical activity like jogging or running. If you are weak and dehydrated, do not attempt to over exert yourself
• Medicines to help decrease vomiting: anti-psychotics have been successfully used to treat the symptoms of CHS in some patients. These medications can have uncomfortable side effects. Some patients report that they would rather continue to throw up than take these medicines. Medicines commonly used to help relieve symptoms: Haldol, Zofran, Ativan, Valium, Morphine, Gravol, Benadryl, Promethazine.

Symptoms often ease within a few days of quitting cannabis but some may experience symptoms for up to 90 days.

To fully get better, you need to stop using marijuana (CBD & THC) all together. Even after quitting cannabis completely, symptoms may reappear due to stress, alcohol, or consumption of foods that contain cannabinoids, like black pepper.
