When Good Goes Too Far: A Thoughtful Look at Cannabis Hyperemesis Syndrome

Written By Heather Dagley
 

Over the past few years, something has been sitting with me — quietly at first, and then more persistently.

It’s a pattern I’ve noticed both anecdotally and increasingly in research: Cannabis Hyperemesis Syndrome (CHS). Cannabis Hyperemesis Syndrome is a recognized condition associated with long-term, heavy high-THC cannabis use and is increasingly being identified in clinical settings.

This isn’t the easiest topic to talk about, especially for those of us who believe deeply in the therapeutic potential of cannabis. But I think it’s a necessary one — because at the end of the day, this work is about helping people live well. And we can’t do that if we’re not willing to look at the full picture.

What is CHS — and Why It Matters

Cannabis Hyperemesis Syndrome is a condition associated with chronic, heavy cannabis use, characterized by recurring episodes of severe nausea and vomiting. For those who experience it, it can be debilitating — often leading to emergency room visits, confusion, and a long road to understanding what’s happening in their body.

 

Many people today face something they never wished to encounter — CHS. Research suggests that the syndrome hits women extra hard.

 

For a long time, CHS has lived in a gray area. Some have questioned whether it’s real, while others have attributed it to pesticides, product quality, or individual predisposition.

But emerging research, and the lived experiences of many individuals, suggest that CHS is real and likely under-recognized.

It’s also important to note that CHS appears to affect a subset of users — not everyone who uses cannabis.

Recent work by reknown cannabis researchers has begun to explore this more deeply, helping to bring clarity to a condition that has often been misunderstood or dismissed. I am heartened by the recent research and sceintific study by Dr. Codi Pederson, Dr. Riley Kirk, and Megan Mbengue. These three are highly respected and cannabis advocates at their core, which makes their take all the more grounded and interesting. Learn more about their research on CHS here.

Holding Both Truths

Here’s where I land:

Cannabis can be a powerful tool for healing. And also — it is not without limits.

Both of these things can be true at the same time.

In the wellness space, we often talk about balance — and cannabis is no exception. Like any substance that interacts with the body, there is a point at which use can shift from supportive to dysregulating. CHS appears to be one example of what can happen when that balance is disrupted over time.

This doesn’t negate the value of the plant. But it does invite a more mature, nuanced conversation around dose, frequency, and long-term use.


A Missed Opportunity in the Industry

If I’m being honest, this is where I feel some disappointment. The cannabis industry, by and large, has not done a great job of engaging with CHS in a responsible, open-minded way.

Too often, the response has been:

  • dismissal

  • deflection

  • or attempts to explain it away

And while some of those perspectives may come from a place of wanting to protect the plant, I believe this approach ultimately does more harm than good.

Because when we avoid or minimize real concerns:

  • we lose credibility

  • we lose trust

  • and we leave space for others to control the narrative

Avoiding or minimizing these experiences doesn’t protect the plant—it weakens trust in the space as a whole. And if we don’t lead with honesty and responsibility, prohibitionist voices or sensationalized media will step in — and likely without the nuance this topic deserves.


Centering the Human Experience

At the heart of this conversation are real people. People who turned to cannabis for relief… and found themselves experiencing something confusing, distressing, and often dismissed.

If cannabis has been part of your wellness routine and something feels off, it’s worth paying attention — not pushing through.

One person I deeply respect in this space is Alice Moon. Read Alice’s story in Forbes here. Alice has openly shared her experience with CHS — despite facing criticism and pushback from within the very industry she has supported. Her story is a powerful reminder that we can honor the plant and speak honestly about its limitations. Her voice, and others like hers, deserve to be met with curiosity, compassion, and respect.


A More Responsible Path Forward

To me, this isn’t about fear — it’s about responsibility.

If we truly believe in cannabis as a tool for wellness, then we have to be willing to:

  • talk about risks

  • acknowledge emerging patterns

  • and support people in using it wisely

That includes conversations around:

  • mindful dosing

  • taking breaks

  • recognizing early warning signs

  • and seeking support when something feels off

 

Cannabis is like everything else — there’s such a thing as too much of a good thing. But we can keep people safe and maintain a thriving industry by sticking with truth, nuance, and a balanced perspective.

 

Final Thoughts

Cannabis has the potential to support health, connection, and healing for many people. But no tool is universally beneficial in every context, at every dose, for every person. CHS is a reminder of that.

My hope is that we can move toward a more balanced and honest conversation — one that honors both the potential and the limits of this plant. Because at the end of the day, cannabis advocacy shouldn’t be about blindly defending cannabis — it’s about supporting people. And people deserve to feel well, informed, and empowered in their choices.

If this is a topic you’re curious about, I encourage you to explore emerging research, listen to patient experiences, and stay open to evolving understanding. As always, informed use is empowered use.


Resources & Further Learning

If you’d like to explore this topic more deeply, here are a few trusted resources that offer both research context and lived experience:

As with any evolving area of research, continuing to learn from both scientific inquiry and lived experience can help us approach cannabis with greater awareness, balance, and care.
