Long-Term Study of Twins Finds No Link Between Legalization, Drug Abuse

Published

on

No significant causal links between cannabis legalization and substance-use disorders were found in this study on twins.

Once again the gateway theory—the belief that cannabis use leads to other drugs, popularized about 40 years ago—is being crushed by new evidence, this time finding no evidence of worsened drug abuse in legal states, using twins as controls. 

A new long-term study examined sets of twins, over 4,000 individuals, and found that state legalization status wasn’t associated with a rise in substance-use disorders of other drugs, and other psychological problems and vulnerabilities. Researchers also noted that legalization led to an increase in cannabis use but decrease in alcohol use disorder (AUD). 

The study, “Recreational cannabis legalization has had limited effects on a wide range of adult psychiatric and psychosocial outcomes,” was published online by Cambridge University Press on Jan. 5. In it, researchers sought to “quantify possible causal effects of recreational cannabis legalization on substance use, substance use disorder, and psychosocial functioning, and whether vulnerable individuals are more susceptible to the effects of cannabis legalization than others.”

Addiction usually goes well beyond the substances involved: The Colorado Sun reports that researchers measured general psychological dysfunction, going beyond substance-use disorders but also measuring financial problems, mental health, community disengagement, and relationship issues that are sometimes believed to be linked to pot use.

After noting that twins consumed cannabis about 20% more in legal states than non-green states in a previous study, the same team of researchers set out again to see if this impacts addiction of other substances, and other psychiatric disorders.

Researchers gathered data from longitudinal studies of twins in two opposing states, one with legal pot and one without: Colorado or Minnesota. The states provided near-perfect controls to examine the full effects of legalization versus a state that prohibits most forms of cannabis. Researchers in both states observed the twins over long periods of time. By using twins there are more automatic controls over socioeconomic status or genetic differences.

Researchers gathered data from 4,078 individuals, first assessed in adolescence and now ages 24-49, and currently residing in states with different cannabis policies (Colorado or Minnesota). Study participants were recruited as teens via birth records from the years 1972–1994, beginning before 2014, when adult-use cannabis stores opened in Colorado. Parents provided informed consent when the study participants were minors.

Living in a legal state was “not associated” with substance abuse disorders, although they found it led to higher pot use but lower alcohol use. Living in a legal state was associated, in fact, with lower AUD rates.

“In the co-twin control design accounting for earlier cannabis frequency and alcohol use disorder (AUD) symptoms respectively, the twin living in a recreational state used cannabis on average more often, and had fewer AUD symptoms than their co-twin living in an non-recreational state. Cannabis legalization was associated with no other adverse outcome in the co-twin design, including cannabis use disorder. No risk factor significantly interacted with legalization status to predict any outcome.”

This led researchers to come to several conclusions.

“Recreational legalization was associated with increased cannabis use and decreased AUD symptoms but was not associated with other maladaptations,” wrote researchers. “These effects were maintained within twin pairs discordant for residence. Moreover, vulnerabilities to cannabis use were not exacerbated by the legal cannabis environment. Future research may investigate causal links between cannabis consumption and outcomes.”

While living in a legal state was associated with higher pot use, it didn’t impact drug abuse and other psychological problems. “At least from the psychological point of view,” Stephanie Zellers, one of the researchers, told The Colorado Sun. “We really didn’t find that the policies (on cannabis legalization) have a lot of negative influence, which I think is important.”

“That twin component really allows us to rule out a lot of possible alternatives—maybe there were just cultural differences, family differences, things like that,” Zellers said, explaining the need to observe twins.

Zellers also led the earlier study looking at the impact of legalization. The team has funded much of the research based on grants from the National Institutes of Health. 

Researchers stipulate that more data is needed to determine the effects of cannabis legalization regarding psychiatric disorders and addiction.

Jio’s 1,600-Satellite LEO Constellation Gets Technical Green Light

Published

on

By

Reliance Jio has crossed a significant milestone in its space connectivity ambitions after its proposal to deploy a Low Earth Orbit (LEO) satellite constellation of around 1,600 satellites received a positive technical assessment from the Indian National Space Promotion and Authorisation Centre (IN-SPACe).

The evaluation, conducted jointly by IN-SPACe, the Indian Space Research Organisation (ISRO), and the Wireless Planning and Coordination (WPC) wing of the Department of Telecommunications, reportedly concluded that Jio’s proposed system meets the required technical standards and is comparable to leading global satellite broadband networks.

India’s Indigenous LEO Satellite Vision

Under the proposal, Reliance Jio plans to deploy between 1,600 and 1,650 satellites in Low Earth Orbit at an altitude of around 650 kilometres.

The planned constellation is expected to provide high-speed satellite connectivity across India, with approximately 32 satellites visible from any location at a given time. The company aims to roll out the network within the next two to three years, subject to regulatory approvals.

According to industry estimates, the satellite system could deliver 4.5 to 5 terabits per second (Tbps) of total data capacity, making it one of the largest satellite broadband projects proposed in India.

The project is expected to require an investment of $10–15 billion (approximately ₹95,000 crore to ₹1.42 lakh crore), reflecting the scale of infrastructure needed for satellite manufacturing, launches, ground stations, and user terminals.

Regulatory Process Moves Forward

Following the successful technical review, the proposal is expected to move into the next phase of regulatory approvals.

The government may now assist Jio in securing orbital slots, coordinating spectrum usage, and filing applications with the International Telecommunication Union (ITU), the global body responsible for managing satellite orbit and frequency allocations.

Obtaining orbital rights remains a critical step, as Low Earth Orbit has become increasingly competitive due to the growing number of satellite broadband projects being planned worldwide.

Officials also indicated that the proposed satellite architecture has been designed to coexist with future Indian LEO constellations, allowing multiple domestic operators to share orbital resources efficiently.

Broadband, Mobile Connectivity, and Strategic Applications

Jio plans to use the satellite network to provide a range of communication services, including satellite broadband, mobile backhaul, enterprise connectivity, and direct-to-device (D2D) satellite communication, particularly in remote and underserved regions where conventional telecom infrastructure is limited.

The company also intends to establish 20 to 22 ground stations across India to support network operations.

Apart from commercial telecommunications, officials have highlighted the project’s potential strategic importance. A domestically developed satellite constellation could strengthen India’s communication infrastructure, reduce dependence on foreign satellite operators, and support national security requirements.

Reports suggest preliminary discussions are underway regarding the possibility of integrating defence-related payloads into some satellites, enabling both civilian and strategic use.

Major Step for India’s Space and Telecom Sectors

Industry analysts view the technical clearance as an important milestone in India’s expanding private space ecosystem. If Jio secures the remaining regulatory approvals and international orbital clearances, the project could become the country’s first large-scale indigenous LEO satellite broadband network.

The initiative also aligns with India’s broader efforts to expand digital connectivity while strengthening its presence in the global satellite communications market.

Alleged Crores Pharma Scam Mastermind Arrested from Surat

Published

on

By

After evading law enforcement for nearly 13 years, an accused linked to a large-scale pharmaceutical fraud case has been arrested by Delhi Police from Surat, Gujarat. The suspect is alleged to have orchestrated a series of financial scams involving fake identities, forged documents, and dishonoured cheques used to procure high-value pharmaceutical raw materials.

Authorities say the accused, identified as Himmat Singh Lodha, is believed to have defrauded multiple pharmaceutical companies in Delhi of goods worth approximately ₹98 lakh before disappearing and remaining underground for years.

Fake Business Deals and Dishonoured Cheques Used in Fraud

Investigators claim the accused posed as a legitimate pharmaceutical trader and placed bulk orders for expensive drug ingredients, offering post-dated cheques as payment security.

In one documented case from 2013, he allegedly obtained around 550 kilograms of Gliclazide, a diabetes-related pharmaceutical ingredient, valued at over ₹26 lakh. When suppliers attempted to encash the cheques, they were reportedly returned with the remark “account closed.”

Following the transaction, the accused allegedly vacated his office and rented residence and disappeared without settling payments. He was later declared a proclaimed offender in 2016 after repeatedly failing to appear before court proceedings. Authorities had also issued a reward for information leading to his arrest.

Multiple Identities and Repeated Fraud Pattern

Police investigations further link the accused to another cheating case dating back to 2012, where he allegedly used a fake identity, “Kailash Jain,” to obtain a large consignment of Ambroxol HCL, a pharmaceutical compound used in cough medications. The value of that consignment was estimated at around ₹72 lakh.

Officials believe the accused followed a consistent modus operandi—posing as a credible businessman, securing high-value goods on deferred payment terms, and then disappearing after delivery while shutting down business operations.

Investigators suspect that forged business records, fake company credentials, and fabricated financial histories were used to build trust with suppliers and gain access to expensive raw materials.

Multi-State Surveillance Leads to Arrest in Surat

A special Crime Branch team tracked the accused through coordinated surveillance efforts across multiple cities, including Mumbai, Ahmedabad, and Surat. After nearly a month of technical monitoring and intelligence gathering, officials located and arrested him from a residential area in Surat.

Authorities also revealed that the accused had been involved in property-related activities while staying under the radar to avoid detection.

Growing Threat of Corporate Identity Fraud

The case highlights a rising trend of organised financial fraud targeting industries that rely heavily on trust-based transactions and deferred payments. Experts note that criminals increasingly exploit gaps in corporate verification systems by using fake GST registrations, temporary offices, and forged documentation to appear legitimate.

Cybercrime and financial fraud specialists warn that such schemes are becoming more complex with the widespread availability of digital business tools, making it easier to create convincing but fraudulent corporate identities.

Experts Urge Stronger Due Diligence in High-Value Transactions

Experts, including former IPS officer and cybercrime specialist Prof. Triveni Singh, emphasize the need for stricter verification procedures in commercial dealings. He noted that relying solely on paperwork or digital business profiles can expose companies to significant financial risk.

Authorities and industry experts recommend physical verification of business operations, bank account validation, and detailed background checks before engaging in high-value or deferred-payment transactions—particularly in sectors like pharmaceuticals, where single consignments can involve transactions worth crores.

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.
