What Climate Produces the Strongest Weed with the Highest THC and CBD Content?

Published

What region grows the the weed with the highest THC and CBD Content?

The cannabis plant contains about 450 chemical components, including terpenes, phenols, fatty acids, amino acids, hydrocarbons, carbohydrates, etc. The two main classes of these are terpenoids and cannabinoids. Numerous cannabis plant strains contain more than 104 cannabinoids. However, the most notable examples are plants used as drugs, specifically 9-THC and 9-tetrahydrocannabinolic acid (9-THCA). Conversely, fiber-type plants are known to contain cannabinoid acids primarily, like cannabigerolic acid (CBGA) and cannabidiol acid (CBDA) and their decarboxylated forms, like canna (CBG) and cannabidiol (CBD).

The popular cannabinoids CBD and THC are the decarboxylation end products of CBDA and THCA, respectively. These cannabinoids have become quite popular thanks to their psychoactive effects and medicinal benefits. To better understand these cannabinoids, Turkish researchers looked into the cannabinoid content of various cannabis strains grown in different climatic zones under various supercritical extraction conditions.

To identify the variations, they examined plants from four distinct geographical areas in Turkey and conducted extractions at two distinct pressures and temperatures. According to the Turkish researchers, the new study results are the first to demonstrate how diverse climatic conditions affect the yield of CBD and THC in distinct cannabis strains.

About the Study

Before planting, the researchers collected four different cannabis seeds. Three of them are fairly popular, but the last one is the first national and domestic seed strain known as “Narl.” Two seeds are from Konya: Papatya and Elnur. The others; are Gökçeaaç from Ankara and Narl from Samsun. As of the end of 2019, Narl was formally registered.

The seedlings were cultivated in four different climate regions in Konya, Turkey. The seeds were planted in the Konya regions of Umra (June 18, 2019), Altnekin (June 13, 2019), Beyşehir (June 14, 2019), and Meram (June 18, 2019) on the designated days.

The central area is Meram. As a result of the higher prevalence of urbanization, this region experiences the highest average yearly temperature. Due to urbanization, humidity is also lower compared to other places. Beyşehir has high humidity and low temperatures since it features one of Turkey’s biggest lakes. The district experiences the most annual precipitation because of the lake.

The areas with the most significant agricultural lands are far away from the city in the regions of Altnekin and Umra, which have moderate temperatures but considerable humidity. In general, each region experiences a different impact of humidity and temperature on local conditions.

Harvesting took place 93 days after planting plants in the Altnekin region, 96 days after growing in both the Beyşehir region and the Meram region, and 104 days after planting in the Umra region. According to the locale, the harvested plants were maintained in a greenhouse without direct sunlight. The plants’ upper and bottom sections were switched at intervals while drying to avoid burning the plant, and they were constantly aired to inhibit mold growth.

The researchers hand-picked the cannabis plants to ensure the careful separation of leaves from their stems. Until the samples reached the grinding conditions, the leaves’ water content was determined using the Karl Fischer method. Using the Supercritical Fluid Extraction (SFE) method, the flow rate of CO2 was maintained at 100 g/min. At the same time, various extraction parameters (temperature, pressure, and co-solvent impact) were examined for their effects on extraction yield and composition.

Result of the Study

The Papatya species grown in the Altnekin region had the highest THC content (90.82%) among the several cannabis strains grown in the various areas and extracted under SFE-verified conditions. This strain produces 3.71% CBD. The Papatya species grown in Altnekin has the second-highest THC output in the dry cannabis plant (5.41%), trailing only the Papatya strain cultivated in Beyşehir (6.14%).

Compared to other strains, the Elnur strain grown in Beyşehir has the second-highest THC ratio (58.22%). This strain has a CBD concentration of 3.29%. This species’ dry cannabis plant extract yield is 4.14%. The Elnur strain, also grown in the Altnekin region, has a THC content of 53.76 percent, and its CBD content is 2.59%. The Papatya species grown in the Beyşehir region (CBD 2.25% and THC 52.16%) was the fourth-ranked strain as regards yield from the strains extracted using SFE after HPLC analysis. With a yield of 6.14%, the Papatya species of the dry cannabis plant, grown in the Beyşehir area, has the most significant output.

When ranked according to yield, the top four strains are two papatya strains and two elnur strains. Beyşehir and Altnekin are the top two cultivating regions, coming in the first four regions. When the locations are compared in terms of their meteorological conditions, the researchers noted that Beyşehir had the most rainfall (1690 mm) during the planting season of 2019 and that the Altnekin region came in second (1070 mm). These two places are also the most humid region when measured by the humidity metric (59.11% and 59.93%, respectively). They are among the less dry locations regarding temperature (13.49 °C and 13.42 °C).

Cannabis can adapt to a wide range of climate conditions. It is a plant that has spread from a warm temperature zone to a subtropical climate zone. While the cannabis plant requires a high need for pre-planting rains, It can grow quickly in humid and arid climates if watered. High humidity and drought also both hasten the growth of cannabis plants. From this vantage point, the two regions (Altnekin and Beyşehir) with the highest yield among those cultivated meet this criterion the best. In terms of the association between climate and the results, the research is consistent.

Conclusion

This study involved the SFE of four cannabis plant strains cultivated in four distinct climate zones. The highest yields of CBD and THC were obtained at 2 hours of conditions of 33 MPa,40 °C, and 2.0 wt% ethanol co-solvent. The characteristic that seemed to affect the extraction yield the most was pressure.

Additionally, it was discovered that the cannabis grown in areas with higher relative humidity, lower temperatures, and more rain had higher yields. Although this work emphasizes the subject to some extent, more research with cannabis strains grown in diverse geographic locations under varied pressure and temperature values is needed to understand and perfect the extraction yield for SFE fully.

EU Pressure Builds on Google as Regulators Face Calls for Massive Fine Over Search Practices

Published

on

By

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

Published

on

By

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?

Published

on

By

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.
