Cannabinoid Hyperemesis Syndrome: What Causes It And How To Treat It
When the syndrome develops, which takes a few years, the consumer will experience various problems such as nausea, vomiting, weight loss, and disturbed eating patterns.
Daily and long-term use of cannabis can cause a rare condition known as cannabinoid hyperemesis syndrome (CHS). Symptoms include nausea and an unsettled stomach, to name just a few.
Many researchers tried to give more details on CHS and its causes, but it requires more studies as it is a fairly new condition. The first cases were reported in 2004 in South Australia, where doctors started treating cannabis users for vomiting, stomach pain, and more. The people who experienced these issues were long-term cannabis users.
Diagnosing the condition is often tricky, considering that many users go for treatment without mentioning using marijuana. In most cases, the symptoms disappear entirely once the user stops consuming cannabis. However, as legalization is still in progress, the number of people using marijuana is increasing, and so is the number of those with CHS.
CHS is a rare phenomenon. In most cases, it occurs in people who use marijuana for years (usually 1-5), a few times per day (3-5 times).
Main Causes of Cannabis Hyperemesis Syndrome
Some research suggests that cannabis hyperemesis syndrome is caused by the daily and long-term use of marijuana. The number of people diagnosed with CHS is increasing due to more states in the US legalizing marijuana. However, the number of regular users who develop weed sickness is not high. Some studies suggest that genetics plays a part. There is a lack of evidence that would fully support the current theories around CHS, which is why further research is necessary.
Cannabis has several active components, and since it is very complex, it affects every user differently. One of its main ingredients is THC that features anti-nausea effects. But what has been noted is that if someone uses cannabis regularly for an extended period, the results could be the opposite. Some theories suggest that THC can make cannabinoid receptors act contrary to how they should behave. As a result, the consumer may experience cramps, vomiting, stomach pain, and other issues.
CHS Symptoms and Phases
The symptoms of CHS are divided into three main phases. The first is called the prodromal phase, the second is hyperemetic, and the third is the recovery phase.

Prodromal Phase
The prodromal phase is the first one, and the symptoms in this stage are usually abdominal pain, morning nausea, and urge to vomit. Other symptoms can be skin flushing, body temperature changes, and sweating. While this phase is on, most people will continue to eat normally. In addition, most users will continue to consume cannabis, thinking it will help them stop nausea and vomiting. The prodromal stage can last for a long time, in some cases for a couple of weeks, months, and even years.
Hyperemetic Phase
The second stage is called the hyperemetic phase, and during it, the vomiting is often pretty intense. To ease nausea, people will mostly use hot showers throughout the day. Some people take marijuana to ease nausea, but it only makes the situation worse.
The symptoms in this phase include feeling sick and nauseous, throwing up after smoking weed, dehydration, stomach pain, disturbance of eating patterns, reduced food intake, and weight loss. The syndrome represents a real medical issue. Extreme vomiting and intense tummy pain can plausibly lead to scromiting (the combination of screaming and vomiting). The phase lasts until the consumer stops with marijuana usage.
Recovery Stage
The last of three phases is the recovery stage. It starts the moment the user stops consuming cannabis. During this phase, all the symptoms will go away, and the person will go back to the standard eating patterns. In addition, people in the recovery phase generally feel better. The need for several hot showers or baths throughout the day will disappear as well. The stage can last from a couple of days to a few months. If an individual decides to turn back to marijuana by any chance, the symptoms will most likely return.
Diagnosis of the Sickness
Various health issues can cause repeated vomiting, and what needs to be pointed out is that CHS is a rare condition. The healthcare provider will ask the patient about the symptoms, and it will also ask about past health and issues if there were any. Then, a physical exam is necessary, including a stomach exam.

One of the things that can make the diagnosis faster and a lot simpler is admitting the consumption of marijuana to the doctor. For many health care providers, diagnosing the syndrome can be pretty challenging and can take a lot of time and effort. The main reason for that is that the patient does not report and mention their use of cannabis.
There are specific criteria to diagnose the syndrome. The first one is the patient has been consuming marijuana regularly for over a year. Some other things that can play a significant role are weekly cannabis usage, tummy pain, relief after taking a hot bath or shower, nausea, vomiting, etc. Other things that are considered are morning nausea, age (if the person is younger than 50), weight loss, and disturbed eating patterns.
Cannabinoid Hyperemesis Syndrome Treatment
If the health care provider diagnoses the CHS, it will be explained to the patient what is cannabinoid hyperemesis syndrome, and then it is the treatment time.
One of the first steps doctors suggest is to stop consuming marijuana. If a person experiences extreme vomiting and nausea, hospitalization that may last a few days could be necessary.

During the second phase, known as the hyperemesis phase, the patient might need treatment, such as:
- Medicines for pain relief and anti-sickness
- Constant hot showers or baths
- Intravenous fluid replacement
- Anti-nausea drugs
All of the above are short-term treatments. The only option to treat the condition long-term is to stop using marijuana.
In most cases, the symptoms of the syndrome will disappear pretty fast. The patient may feel much better in general within a few days, usually one or two. However, the symptoms can come back if the person starts consuming cannabis again.
Prevention and Consequences If Untreated
The only way to prevent cannabinoid hyperemesis syndrome is the complete absence of marijuana consumption. Unfortunately, people tend to consume cannabis for years and become chronic users before the CHS develops. That’s because the development of the syndrome takes a lot of time.
When a person has the symptoms, especially vomiting, it may cause additional issues such as dehydration. In addition, if the condition is not treated, some other complications may arise, such as weakness, muscle spasms, shock, to name a few. In the most severe cases, cannabinoid hyperemesis syndrome can lead to kidney failure that can cause death.
Conclusions
CHS is caused by regular marijuana consumption. When the syndrome develops, which takes a few years, the consumer will experience various problems such as nausea, vomiting, weight loss, disturbed eating patterns, etc. The symptoms take three phases, and they can be extremely severe, especially in phase two.
The diagnosis of the syndrome is one of the trickiest parts of the story because people often fail to report using marijuana to their health care providers. Once the syndrome is finally diagnosed, the patient gets familiar with the condition, learns what CHS is, and begins treatment. The most important part of the recovery process is the stopping of weed consumption. If the patient continues to consume, the symptoms will come back.
The condition is a rare phenomenon and it does not affect all smokers. Every marijuana user should know the right dose. When the marijuana consumer experiences extreme vomiting for one whole day or more, contacting a health care provider is the best possible option.

EU Pressure Builds on Google as Regulators Face Calls for Massive Fine Over Search Practices
A growing coalition of European industry groups is intensifying pressure on regulators to take decisive action against Google over allegations of unfair search practices that could reshape competition rules across the region’s digital economy.
Investigation Under Digital Markets Act Gains Momentum
The case is being examined by the European Commission under the European Union’s landmark Digital Markets Act (DMA), introduced to curb the dominance of major technology platforms and ensure fair competition.
Launched in March 2024, the investigation focuses on whether Google has been prioritising its own services in search results, potentially disadvantaging rival businesses that rely on online visibility to reach customers.
Industry Groups Demand Swift Action
Several prominent European organizations have jointly urged regulators to conclude the probe without further delay. They argue that prolonged investigations allow alleged anti-competitive practices to continue, putting European companies—especially startups—at a disadvantage.
Signatories include the European Publishers Council, the European Magazine Media Association, the European Tech Alliance, and EU Travel Tech.
In a joint statement, these groups warned that delays in enforcement are affecting innovation, profitability, and growth prospects for regional businesses competing in digital markets.
Google Denies Allegations
Google has rejected claims of bias, stating that its search algorithms are designed to deliver the most relevant and useful results to users. The company has also proposed adjustments to address regulatory concerns.
However, critics argue that these changes are insufficient and fail to address the core issue of market dominance.
Potential Billion-Euro Penalties
If found in violation of the DMA, Google could face significant financial penalties. Under EU rules, fines can reach a substantial percentage of a company’s global turnover, potentially amounting to billions of euros.
Regulators may also impose corrective measures requiring changes to business practices, which could have long-term implications for how digital platforms operate in Europe.
Wider Implications for Big Tech
The case highlights ongoing tensions between European regulators and major U.S. technology firms. In recent years, the EU has taken a more aggressive stance in enforcing competition laws, aiming to create a level playing field for local businesses.
A final ruling against Google could set a major precedent, influencing future enforcement actions and shaping the regulatory landscape for global tech companies operating within Europe.
As scrutiny intensifies, the outcome of the investigation is expected to play a critical role in defining the future of digital competition across the European Union.

Amazon Faces Potential Criminal Trial in Italy Over €1.2 Billion Tax Evasion Allegations
Milan: U.S. tech giant Amazon is facing the prospect of a major legal showdown in Italy, after prosecutors in Milan formally requested a court to move forward with criminal proceedings over alleged tax evasion totaling approximately ₹12,500 crore (€1.2 billion).
The case targets Amazon’s European division along with four senior executives, marking one of the most significant tax-related investigations involving a global e-commerce platform in Europe.
Trial Push Despite Multi-Million Euro Settlement
The move comes even after Amazon reached a financial settlement with Italian tax authorities in December, agreeing to pay around ₹5,500 crore (€527 million), including interest, to resolve part of the dispute.
Typically, such settlements lead to the closure of criminal investigations. However, Milan prosecutors have opted to proceed, signaling a tougher stance on alleged corporate tax violations.
A preliminary hearing is expected in the coming months, where a judge will decide whether to formally indict the company and its executives or dismiss the case.
Allegations of VAT Evasion Through Marketplace Sellers
At the center of the investigation are claims that Amazon’s platform enabled non-European Union sellers to avoid paying value-added tax (VAT) on goods sold to Italian consumers between 2019 and 2021.
Prosecutors allege that the company’s marketplace structure allowed thousands of foreign vendors—many reportedly based in China—to operate without fully disclosing their identities or tax obligations. This, authorities argue, led to substantial VAT losses for the Italian government.
Under Italian law, online platforms facilitating sales can be held partially liable if third-party sellers fail to comply with tax requirements, a key point in the prosecution’s case.
Italian Government Named as Affected Party
In their filing, prosecutors identified Italy’s Economy Ministry as the injured party, citing significant financial damage resulting from the alleged tax evasion.
Legal experts say the outcome of the case could have wide-ranging implications across the European Union, where VAT systems are harmonized and similar compliance rules apply to digital marketplaces.
Multiple Investigations Add to Pressure
The VAT probe is just one of several legal challenges facing Amazon in Italy. The European Public Prosecutor’s Office is reportedly examining additional tax-related issues covering more recent years.
Meanwhile, Milan authorities are pursuing separate investigations into alleged customs fraud linked to imports from China and whether Amazon maintained an undeclared “permanent establishment” in Italy—potentially exposing it to higher tax liabilities.
In a separate regulatory action, Italy’s data protection authority recently ordered an Amazon unit to stop using personal data from over 1,800 employees at a warehouse near Rome.
Amazon Denies Allegations
Amazon has consistently denied wrongdoing and indicated it will strongly contest the allegations in court if the case proceeds. The company has also warned that prolonged legal uncertainty could impact investor confidence and Italy’s appeal as a destination for international business.
Broader Impact on Europe’s Digital Economy
If the case moves to trial, it could become a landmark moment for the regulation of global e-commerce platforms in Europe. Governments across the region are increasingly scrutinizing how digital marketplaces handle tax compliance, especially in cross-border transactions.
With online retail continuing to expand, regulators are under mounting pressure to ensure that multinational platforms and third-party sellers adhere to the same tax rules as traditional businesses.

IndiGo Crisis Exposes Risks of Monopoly: What If Telecom or E-commerce Collapses Next?
Airports across India witnessed scenes of distress and confusion as thousands of passengers were stranded due to IndiGo’s massive flight disruptions. Families with medical emergencies, funerals, and personal crises were left helpless as the airline cancelled hundreds of flights without adequate communication or support.
Passengers described desperate situations — a mother pleading for sanitary pads for her daughter, a woman unable to transport her husband’s coffin, and others stranded while trying to reach family funerals or hospitals. “It was like a lockdown at the airport,” one passenger said, describing the panic that unfolded as IndiGo’s mismanagement crippled operations nationwide.
Root Cause: IndiGo’s Market Monopoly
The turmoil, industry experts argue, stems from IndiGo’s monopolistic control over India’s domestic aviation market. The airline operates nearly 2,100 flights daily and holds around 60% market share — meaning every second plane flying within India belongs to IndiGo.
This dominance has given the company unparalleled influence. When IndiGo falters, the entire aviation system suffers. Passengers are left with few alternatives, as other airlines lack capacity to absorb stranded travellers. The result: skyrocketing ticket prices, chaos at terminals, and total dependence on a single private operator.
Aviation pioneer Captain G.R. Gopinath, founder of Air Deccan, criticised the government’s inaction, noting that on some routes, IndiGo’s economy fares surged to ₹1 lakh. He compared the situation to a hostage crisis, writing that the airline “held the system ransom” and forced regulators to defer new safety rules meant to protect pilots and passengers.
Government Intervention and Regulatory Weakness
The crisis erupted after IndiGo failed to comply with the Flight Duty Time Limitations (FDTL) — rules introduced by the DGCA in January 2024 requiring adequate rest for pilots. Despite having nearly two years to adapt, IndiGo blamed the rule for operational disruptions, citing a shortage of pilots.
Under mounting public pressure, the government stepped in, temporarily relaxing FDTL norms and capping airfare hikes. Officials claimed the move was to protect passengers, but analysts say it exposed the state’s vulnerability to corporate monopolies. “The government had no option but to yield,” said one aviation policy expert, pointing out that ignoring safety regulations for short-term relief could have long-term consequences.
The crisis also rekindled memories of the June 2025 Air India crash near London, which claimed over 240 lives. Experts warn that compromising pilot rest and safety standards to maintain flight schedules could risk another tragedy.
If Telecom Giants Fail: A National Paralysis
The article raises a troubling question — what if a similar crisis struck the telecom sector, where Jio and Airtel together control nearly 80% of subscribers and serve over 780 million users?
If both networks failed simultaneously, the repercussions would be catastrophic. Internet shutdowns would halt UPI transactions, online banking, OTP verifications, video calls, OTT streaming, and emergency communications. Critical services such as airports, hospitals, stock exchanges, and small businesses — many of which rely on WhatsApp and digital payments — would come to a standstill.
In essence, a telecom breakdown could paralyse India’s digital economy, exposing the nation’s dependence on a duopoly.
E-commerce Monopoly: Another Fragile Ecosystem
The same risk looms over the e-commerce sector, where Amazon and Flipkart dominate nearly 80% of the market. A disruption similar to IndiGo’s could cripple daily life — halting delivery of groceries, medicines, and essential goods, freezing refunds and customer support, and leaving small sellers without platforms to trade.
Local retailers, freed from competition, might exploit shortages by inflating prices. Such a scenario underscores the perils of market centralisation in sectors critical to everyday living.
A Wake-Up Call for Regulators
The IndiGo crisis, analysts say, is a warning shot for policymakers and regulators. A single company’s operational failure exposed systemic weaknesses in India’s infrastructure and consumer protection mechanisms.
As the aviation regulator DGCA investigates and IndiGo works to restore normalcy, the broader lesson remains clear: unchecked monopoly power in any essential service — whether air travel, telecom, or e-commerce — poses a direct threat to economic stability and citizen welfare.
Without stronger competition laws, redundancy frameworks, and regulatory oversight, India risks repeating this crisis across multiple sectors — each time with millions of citizens paying the price.
