Recovery from Cannabinoid Hyperemesis Syndrome (CHS) requires complete cessation of cannabis use, and recovery times can vary significantly depending on the individual. While many people begin experiencing relief within 10 days of stopping cannabis use, full recovery often takes anywhere from several weeks to six months, depending on factors such as the duration of cannabis use, metabolism, and overall health.
CHS is a condition caused by chronic, long-term cannabis use that leads to severe nausea, repeated vomiting, and abdominal pain. The condition develops over time and progresses through three distinct stages, each with its own symptoms and challenges.
The prodromal phase is the initial stage, lasting anywhere from months to years. During this phase, individuals may experience morning nausea, occasional abdominal discomfort, and an unusual reliance on cannabis as a means to relieve these symptoms. Paradoxically, cannabis use during this time often worsens the underlying issue, even if temporary relief is perceived.
The hyperemetic phase marks the acute and most severe stage of CHS. Symptoms include persistent nausea, repeated vomiting that can occur in cycles, intense abdominal pain, dehydration, and unintentional weight loss. Individuals may take frequent hot showers or baths during this stage because heat is known to provide temporary relief. However, these measures do not address the root cause, and symptoms continue until cannabis use stops entirely.
The final stage, the recovery phase, begins after cannabis cessation. During this period, symptoms gradually diminish, and the body begins the healing process. While improvement is noticeable within days for some people, returning to cannabis use almost always triggers a recurrence of CHS, sending individuals back to the hyperemetic stage.
The recovery timeline can vary, but most individuals experience an initial period of relief within a few days. During the first 24-72 hours of hospitalization or treatment, symptoms like nausea and vomiting begin to subside as the body rehydrates and stabilizes. While this initial recovery brings noticeable relief, it represents only the start of the healing process.
For full recovery, individuals must abstain completely from cannabis use. Most people achieve complete resolution of symptoms within one to three months. However, the exact duration depends on factors such as how long cannabis was used, the frequency of use, and the individual’s body composition. Because cannabinoids like THC are stored in fat cells, those with higher body fat percentages or longer histories of heavy cannabis use may take several months to fully recover. In some cases, lingering symptoms such as fatigue, mild nausea, or appetite changes can persist for up to six months.
Managing CHS requires a combination of short-term medical interventions and long-term changes to lifestyle and behavior. During the acute hyperemetic phase, medical treatment focuses on relieving symptoms and addressing complications such as dehydration and electrolyte imbalances. Intravenous fluids are commonly administered to restore hydration, and anti-nausea medications, such as ondansetron, may be prescribed to control vomiting. In severe cases, medications like haloperidol or olanzapine have been used to reduce symptoms and provide temporary relief. Proton pump inhibitors may also be recommended to protect the stomach lining from acid damage caused by frequent vomiting.
The most critical aspect of long-term recovery is complete cessation of cannabis use. Continuing to use cannabis, even in small amounts, almost always leads to a relapse of symptoms, restarting the cycle of nausea, vomiting, and abdominal pain. For individuals struggling to quit cannabis, professional support in the form of drug rehabilitation programs, cognitive behavioral therapy, or counseling can provide the tools needed to achieve abstinence and maintain recovery.
If left untreated, CHS can lead to serious health complications that extend beyond the initial symptoms. Chronic vomiting causes severe dehydration and electrolyte imbalances, which can impact kidney function and, in rare cases, lead to acute kidney injury. Repeated vomiting also contributes to erosion of tooth enamel and damage to the esophagus, increasing the risk of long-term gastrointestinal problems. Severe dehydration, if not addressed, can result in complications such as brain swelling, which poses life-threatening risks. These potential outcomes emphasize the importance of identifying and treating CHS as early as possible.
The only proven way to prevent CHS is to completely avoid cannabis use, particularly for individuals who have experienced symptoms in the past. After successful recovery, many people notice significant improvements in their overall health, including better cognitive function, improved sleep quality, and enhanced mental well-being.
For those at risk of developing CHS or struggling with cannabis dependency, seeking professional help is essential. Rehabilitation programs, therapy, and structured support systems can provide the guidance needed to quit cannabis and prevent relapse. Building a healthier lifestyle through improved nutrition, regular exercise, and stress management techniques can also help support long-term recovery and reduce the chances of developing other health concerns.
Recovering from Cannabinoid Hyperemesis Syndrome is entirely possible with complete abstinence from cannabis use. While the recovery process may take time—ranging from a few weeks to several months—most individuals find that symptoms gradually diminish and their overall health improves. For those struggling to stop cannabis use, professional support is available to guide you through the process and ensure long-term success.
If you or someone you know is experiencing symptoms of CHS, seeking medical attention is the first step toward relief and recovery. Remember, CHS can be effectively managed, and a healthier, symptom-free life is within reach.

We firmly believe that the internet should be available and accessible to anyone, and are committed to providing a website that is accessible to the widest possible audience, regardless of circumstance and ability.
To fulfill this, we aim to adhere as strictly as possible to the World Wide Web Consortium’s (W3C) Web Content Accessibility Guidelines 2.1 (WCAG 2.1) at the AA level. These guidelines explain how to make web content accessible to people with a wide array of disabilities. Complying with those guidelines helps us ensure that the website is accessible to all people: blind people, people with motor impairments, visual impairment, cognitive disabilities, and more.
This website utilizes various technologies that are meant to make it as accessible as possible at all times. We utilize an accessibility interface that allows persons with specific disabilities to adjust the website’s UI (user interface) and design it to their personal needs.
Additionally, the website utilizes an AI-based application that runs in the background and optimizes its accessibility level constantly. This application remediates the website’s HTML, adapts Its functionality and behavior for screen-readers used by the blind users, and for keyboard functions used by individuals with motor impairments.
If you’ve found a malfunction or have ideas for improvement, we’ll be happy to hear from you. You can reach out to the website’s operators by using the following email
Our website implements the ARIA attributes (Accessible Rich Internet Applications) technique, alongside various different behavioral changes, to ensure blind users visiting with screen-readers are able to read, comprehend, and enjoy the website’s functions. As soon as a user with a screen-reader enters your site, they immediately receive a prompt to enter the Screen-Reader Profile so they can browse and operate your site effectively. Here’s how our website covers some of the most important screen-reader requirements, alongside console screenshots of code examples:
Screen-reader optimization: we run a background process that learns the website’s components from top to bottom, to ensure ongoing compliance even when updating the website. In this process, we provide screen-readers with meaningful data using the ARIA set of attributes. For example, we provide accurate form labels; descriptions for actionable icons (social media icons, search icons, cart icons, etc.); validation guidance for form inputs; element roles such as buttons, menus, modal dialogues (popups), and others. Additionally, the background process scans all the website’s images and provides an accurate and meaningful image-object-recognition-based description as an ALT (alternate text) tag for images that are not described. It will also extract texts that are embedded within the image, using an OCR (optical character recognition) technology. To turn on screen-reader adjustments at any time, users need only to press the Alt+1 keyboard combination. Screen-reader users also get automatic announcements to turn the Screen-reader mode on as soon as they enter the website.
These adjustments are compatible with all popular screen readers, including JAWS and NVDA.
Keyboard navigation optimization: The background process also adjusts the website’s HTML, and adds various behaviors using JavaScript code to make the website operable by the keyboard. This includes the ability to navigate the website using the Tab and Shift+Tab keys, operate dropdowns with the arrow keys, close them with Esc, trigger buttons and links using the Enter key, navigate between radio and checkbox elements using the arrow keys, and fill them in with the Spacebar or Enter key.Additionally, keyboard users will find quick-navigation and content-skip menus, available at any time by clicking Alt+1, or as the first elements of the site while navigating with the keyboard. The background process also handles triggered popups by moving the keyboard focus towards them as soon as they appear, and not allow the focus drift outside it.
Users can also use shortcuts such as “M” (menus), “H” (headings), “F” (forms), “B” (buttons), and “G” (graphics) to jump to specific elements.
We aim to support the widest array of browsers and assistive technologies as possible, so our users can choose the best fitting tools for them, with as few limitations as possible. Therefore, we have worked very hard to be able to support all major systems that comprise over 95% of the user market share including Google Chrome, Mozilla Firefox, Apple Safari, Opera and Microsoft Edge, JAWS and NVDA (screen readers).
Despite our very best efforts to allow anybody to adjust the website to their needs. There may still be pages or sections that are not fully accessible, are in the process of becoming accessible, or are lacking an adequate technological solution to make them accessible. Still, we are continually improving our accessibility, adding, updating and improving its options and features, and developing and adopting new technologies. All this is meant to reach the optimal level of accessibility, following technological advancements. For any assistance, please reach out to
