Cannabis helps a lot of people. For stress, for sleep, for chronic pain—it’s part of many routines. But for some long-term users, something unexpected can happen.

It’s called Cannabinoid Hyperemesis Syndrome, or CHS.

What Is CHS?

CHS is a condition that causes recurring nausea, vomiting, and stomach discomfort in some people who’ve used cannabis over time. It often shows up years into regular use, which is part of why it can be so confusing.

One of the more unique signs is that hot showers seem to help, at least for a little while. That pattern has helped many people recognize what’s going on.

The Three Phases of CHS

Understanding CHS often means recognizing its progression through three distinct phases:

1. Prodromal Phase

  • Morning nausea
  • Abdominal discomfort
  • Fear of vomiting
  • Maintained appetite
  • Symptoms may last months to years

2. Hyperemetic Phase

  • Intense, persistent nausea and vomiting
  • Abdominal pain
  • Decreased food intake
  • Weight loss
  • Compulsive hot bathing or showering

3. Recovery Phase

  • Gradual return to normal eating patterns
  • Absence of nausea and vomiting
  • Return to normal bathing habits
  • Can take days to months

It Doesn’t Mean Cannabis Is Bad

CHS isn’t a judgment on cannabis or a reason to panic. It’s just something that can happen for certain people. Everyone’s body is different, and our relationship with cannabis can change over time.

CHS is still being studied. There’s a lot we don’t know, but it’s real and worth understanding.

Why Does This Happen?

While researchers are still studying the exact mechanisms, current theories suggest:

  • Receptor Overstimulation: Long-term cannabis use may overstimulate cannabinoid receptors
  • Individual Sensitivity: Some people may be more susceptible due to genetic factors
  • Dose and Duration: Higher frequency and longer duration of use may increase risk
  • Product Potency: Today’s cannabis products are often much stronger than in the past

If You’re Dealing With It

You might feel like no one believes you. Maybe you’ve been to the ER more than once. Maybe you’ve tried cutting out foods, changing routines, or just waiting it out.

If that sounds familiar, you’re not alone.

There’s a growing community of people talking about this. More doctors are learning to recognize it. And more resources are becoming available for people trying to make sense of what they’re experiencing.

Common Experiences

Many people with CHS report:

  • Medical Confusion: Multiple ER visits before getting a diagnosis
  • Disbelief from Others: Friends or family who don’t understand
  • Isolation: Feeling alone in their experience
  • Financial Stress: Medical bills from repeated hospital visits
  • Lifestyle Disruption: Missing work, school, or social activities

What To Try

If you think CHS might be affecting you, here are a few things that can help:

Immediate Relief Strategies

  • Hot Showers/Baths: Many find temporary relief in hot water
  • Topical Heat: Heating pads or hot water bottles on the abdomen
  • Stay Hydrated: Small, frequent sips of clear fluids
  • Rest: Give your body time to recover

Documentation and Medical Care

  • Keep a record of your symptoms and when they happen
  • Notice how your body reacts during breaks or changes in your cannabis use
  • Talk to a doctor you trust, and be prepared to explain CHS if they aren’t familiar
  • Bring documentation of your symptoms and cannabis use history

Long-term Management

The most effective treatment for CHS is cannabis cessation. While this can be challenging, many people find:

  • Gradual Reduction: Slowly decreasing use over time
  • Complete Breaks: Taking extended periods away from cannabis
  • Professional Support: Working with healthcare providers or counselors
  • Alternative Therapies: Exploring other options for the conditions cannabis was treating
