As cannabis use becomes more popular for both medical and recreational purposes, a lesser-known condition has begun to gain attention: Cannabinoid Hyperemesis Syndrome (CHS). This rare and often misunderstood condition can cause severe nausea, vomiting, and abdominal pain in frequent cannabis users. Here’s a simple breakdown of what CHS is, its symptoms, and how it can be managed.
CHS is a syndrome that can affect people who use cannabis regularly over long periods, resulting in repeated bouts of nausea, vomiting, and stomach pain. Ironically, while cannabis is often known for its anti-nausea effects, frequent or long-term use can lead to this unexpected reaction. According to recent studies, CHS is becoming more recognized by healthcare professionals, though it is still often misdiagnosed due to its paradoxical symptoms.
CHS typically follows a pattern with three stages:
- Prodromal Phase: In the initial stage, mild nausea, especially in the mornings, and some stomach discomfort begin. People in this phase might feel an urge to vomit but may not yet link these symptoms to cannabis use.
- Hyperemetic Phase: This is the severe phase, where symptoms become more intense, including persistent nausea, frequent vomiting, and intense abdominal pain. Many people with CHS find relief from these symptoms by taking hot showers or baths, which temporarily ease discomfort. During this stage, dehydration from excessive vomiting can lead some to seek medical attention.
- Recovery Phase: Once cannabis use stops, symptoms gradually subside, and people feel better. However, if cannabis use is resumed, the symptoms often come back and can be even more intense than before.
The exact cause of CHS isn’t fully understood, though research suggests several theories. One hypothesis is that chronic cannabis use affects certain receptors in the brain that regulate nausea and vomiting.
Another theory proposes that specific cannabinoids in cannabis may trigger these symptoms in certain individuals after prolonged use. According to recent studies, CHS may involve genetic or environmental factors, though more research is needed to fully understand why it only affects some users.
Currently, the only proven treatment for CHS is to
stop using cannabis. When someone with CHS quits cannabis, their symptoms generally go away over time. In severe cases, medical care may be necessary to manage dehydration and other complications.
While some people report temporary relief from hot showers or baths, these measures don’t address the underlying cause of CHS and won’t prevent symptoms from returning if cannabis use continues.
CHS mainly affects people who use cannabis heavily and over a long period, although it doesn’t impact all frequent users. According to recent studies, factors like individual genetics, frequency of use, and the specific type of cannabis products consumed might play a role in who develops CHS.
If you’re a regular cannabis user and experience symptoms like nausea, vomiting, and abdominal pain, especially if these improve with hot showers, CHS might be worth considering. Recent studies suggest that increased awareness of CHS could help with early diagnosis and improve outcomes by preventing severe dehydration and complications.
Cannabinoid Hyperemesis Syndrome is rare, but for those affected, it can be highly uncomfortable. Recognizing the symptoms early and knowing how to respond is essential, especially as cannabis use continues to grow in popularity. For anyone using cannabis for medical reasons, being informed about potential conditions like CHS can help ensure a healthy and balanced approach to cannabis use.
