A hazy legal landscape means people can get high on hemp products, even where pot is prohibited

In Texas, where I live, marijuana has long been illegal. Yet on a busy street in my Houston neighborhood, at least five stores within a half-mile of each other sell cannabis products that promise a strong high.

Texas isn’t alone. Due to a mix of recent legal changes and an uncertain policy landscape, residents in roughly half of American states have easy access to impairing hemp products that bear a strong resemblance to marijuana and are far less regulated.

As hemp sales soar – reaching nearly US$3 billion in 2023 – a number of states are tightening their restrictions, while experts are analyzing the public health implications. That’s why I analyzed hemp policies in all 50 states with some of my colleagues at Rice University’s Baker Institute, where I’m a drug policy fellow.

Marijuana and hemp: Same plant, different policies

Marijuana and hemp are both varieties of cannabis sativa, a plant with many uses that produces thousands of compounds. Among them is the popular intoxicant delta-9 tetrahydrocannabinol, or delta-9 THC.

Hemp is widely valued as an industrial crop, and for most of American history, farmers freely cultivated it. But by the mid-20th century, lawmakers had grown increasingly opposed to marijuana and were concerned by hemp’s similarity to its impairment-causing cousin.

In an effort to permit hemp cultivation while prohibiting production of a psychoactive plant, the Agricultural Marketing Act of 1946 defined hemp as all parts of the cannabis plant with less than 0.3 percent concentration of delta-9 THC by dry weight. Cannabis that exceeded this threshold was considered marijuana.

The 1970 Controlled Substances Act ushered in the modern era of prohibition of marijuana and other drugs. Hemp remained technically legal, but because of its similarity to marijuana, it was listed as a Schedule I drug, alongside heroin and other substances deemed to have a high potential for abuse and no medical value.

Because of hemp’s Schedule I status, the Drug Enforcement Administration tightly regulated its production. But hemp farmers have long argued that these regulations were excessive – and in 2018, Congress agreed. That year, lawmakers passed a farm bill that removed hemp from the Controlled Substances Act and legalized the manufacture and sale of hemp and its derivatives.

The ABC News affiliate in San Diego reports on the 2018 farm bill from a local perspective.

Crucially, the 2018 bill still defines hemp as all parts of the plant and its derivatives that have less than 0.3 percent delta-9 THC. But it left a loophole: While delta-9 is the most well-known form of THC, it’s not the only one. Other forms of THC, known as THC isomers, have similar effects. These isomers, like delta-8 and delta-10 THC, can be derived from the hemp plant, and like delta-9 THC, they can cause impairment. The 2018 Farm Bill legalized all of them.

In 2023, sales of hemp-derived cannabinoids reached US$2.8 billion. Market growth has been accompanied by a rise in adverse health events. Chemists have expressed alarm at how some hemp products are made, and analyses of commercially available products have found them to contain heavy metals, residual solvents and pesticides.

Given the lax regulatory environment, many public officials now question the lack of guardrails on this burgeoning hemp industry. As a result, officials and governments across the country are now enacting or considering policy changes.

Some states are imposing age and advertising restrictions

In 2023, 11.4% of 12th graders said they had used hemp-derived delta-8 THC in the past year. Easy access to any substance can encourage use, and THC can have negative impacts on the adolescent brain.

While federal law prohibits the sale of tobacco and alcohol to individuals under 21, there is no similar national requirement for hemp. But at least 27 states that permit the sale of hemp-derived products now have minimum age requirements, and several others have pending legislation.

Lessons from the tobacco market also demonstrate that advertising restrictions can reduce the use of legal but potentially harmful products. Most efforts to curtail hemp advertising focus on youth. Sixteen states restrict the use of packaging and marketing materials that may appeal to minors. Meanwhile, federal regulations also limit youth-targeted marketing.

There are fewer restrictions on advertising to adults. The Food and Drug Administration does prohibit using unverified health claims to sell hemp products, but this standard gives the industry plenty of leeway. Hemp ads often tout their purported physical benefits, like reducing pain or improving sleep, or portray them as mood-boosters that can make one feel euphoric and aroused, with few downsides.

Other states are establishing potency limits

The use of products high in THC has been linked to greater risk of cannabis dependence and adverse mental health outcomes. Concerns about product potency have led all states with recreational marijuana markets to limit the amount of delta-9 THC in edible products. This threshold is typically around 10 milligrams, a dose that’s strong enough to affect most people.

Hemp is a different story. To satisfy federal requirements, hemp just has to have less than 0.3% delta-9 THC by weight. This limit sounds low, but the weight-based metric does not account for heavier products, like food and drinks.

For example, a 50-gram candy bar – roughly the size of a Snickers bar – with 150 milligrams of hemp-derived delta-9 THC is legal in the 34 states that don’t have milligram caps on hemp products. This is a dose 15 times higher than what any recreational marijuana market allows. Meanwhile, states that only restrict hemp’s delta-9 content also leave the door open to products with high amounts of other forms of THC.

At least 13 states have responded to potency concerns by adding milligram caps on the total THC permitted in a single serving of a hemp product. Some of these limits are so low – 1 milligram or less in Connecticut, New York, Montana and Rhode Island – that one serving is unlikely to cause impairment.

Enforcement is a wild card

Only regulations that are enforced are effective, and states differ in the level of energy they devote to industry oversight.

In Virginia, the Office of Hemp Enforcement has issued over $12 million in fines to noncompliant hemp retailers since its creation in 2023. On the other end of the spectrum, Massachusetts considers hemp-derived THC products illegal, but it has not provided local jurisdictions with funding for enforcement, resulting in continued availability of prohibited products.

Some states with legal hemp markets have added additional sales taxes to help fund enforcement. In Nebraska, Missouri and Connecticut, attorneys general have sued hemp retailers for selling illegal items, marketing to minors and engaging in deceptive trade practices.

As the hemp industry expands, so will concerns about how to protect public health. The demand for THC, and the market to supply it, continues to grow. If lawmakers want to develop industrywide safety standards or deal with the challenges of online marketplaces that sell hemp products to minors, it will take action from Washington. In the meantime, many states and policymakers are exploring an expansive middle ground between unfettered access and blanket bans.The Conversation

AI is transforming weather forecasting − and that could be a game changer for farmers around the world

Climate change intensifies weather risks for farmers, affecting crop yields and incomes, especially in low- and middle-income countries lacking accurate forecasts due to costly traditional models. AI-powered weather forecasting offers a breakthrough by delivering accurate, localized predictions rapidly and inexpensively, using far less computational power than physics-based systems. Advanced AI models like Pangu-Weather and GraphCast now match or surpass traditional forecasts, enabling timely, high-resolution weather guidance on standard computers. To be effective, AI forecasts must be tailored to local agricultural needs and disseminated through accessible channels. Supported by organizations such as AIM for Scale, AI forecasting can empower developing countries to adapt farming practices and improve resilience amid climate change.

For farmers, every planting decision carries risks, and many of those risks are increasing with climate change. One of the most consequential is weather, which can damage crop yields and livelihoods. A delayed monsoon, for example, can force a rice farmer in South Asia to replant or switch crops altogether, losing both time and income.

Access to reliable, timely weather forecasts can help farmers prepare for the weeks ahead, find the best time to plant or determine how much fertilizer will be needed, resulting in better crop yields and lower costs.

Yet, in many low- and middle-income countries, accurate weather forecasts remain out of reach, limited by the high technology costs and infrastructure demands of traditional forecasting models.

A new wave of AI-powered weather forecasting models has the potential to change that.

By using artificial intelligence, these models can deliver accurate, localized predictions at a fraction of the computational cost of conventional physics-based models. This makes it possible for national meteorological agencies in developing countries to provide farmers with the timely, localized information about changing rainfall patterns that the farmers need.

The challenge is getting this technology where it’s needed.

Why AI forecasting matters now

The physics-based weather prediction models used by major meteorological centers around the world are powerful but costly. They simulate atmospheric physics to forecast weather conditions ahead, but they require expensive computing infrastructure. The cost puts them out of reach for most developing countries.

Moreover, these models have mainly been developed by and optimized for northern countries. They tend to focus on temperate, high-income regions and pay less attention to the tropics, where many low- and middle-income countries are located.

A major shift in weather models began in 2022 as industry and university researchers developed deep learning models that could generate accurate short- and medium-range forecasts for locations around the globe up to two weeks ahead.

These models worked at speeds several orders of magnitude faster than physics-based models, and they could run on laptops instead of supercomputers. Newer models, such as Pangu-Weather and GraphCast, have matched or even outperformed leading physics-based systems for some predictions, such as temperature.

AI-driven models require dramatically less computing power than the traditional systems.

While physics-based systems may need thousands of CPU hours to run a single forecast cycle, modern AI models can do so using a single GPU in minutes once the model has been trained. This is because the intensive part of the AI model training, which learns relationships in the climate from data, can use those learned relationships to produce a forecast without further extensive computation – that’s a major shortcut. In contrast, the physics-based models need to calculate the physics for each variable in each place and time for every forecast produced.

While training these models from physics-based model data does require significant upfront investment, once the AI is trained, the model can generate large ensemble forecasts — sets of multiple forecast runs — at a fraction of the computational cost of physics-based models.

Even the expensive step of training an AI weather model shows considerable computational savings. One study found the early model FourCastNet could be trained in about an hour on a supercomputer. That made its time to presenting a forecast thousands of times faster than state-of-the-art, physics-based models.

The result of all these advances: high-resolution forecasts globally within seconds on a single laptop or desktop computer.

Research is also rapidly advancing to expand the use of AI for forecasts weeks to months ahead, which helps farmers in making planting choices. AI models are already being tested for improving extreme weather prediction, such as for extratropical cyclones and abnormal rainfall.

Tailoring forecasts for real-world decisions

While AI weather models offer impressive technical capabilities, they are not plug-and-play solutions. Their impact depends on how well they are calibrated to local weather, benchmarked against real-world agricultural conditions, and aligned with the actual decisions farmers need to make, such as what and when to plant, or when drought is likely.

To unlock its full potential, AI forecasting must be connected to the people whose decisions it’s meant to guide.

That’s why groups such as AIM for Scale, a collaboration we work with as researchers in public policy and sustainability, are helping governments to develop AI tools that meet real-world needs, including training users and tailoring forecasts to farmers’ needs. International development institutions and the World Meteorological Organization are also working to expand access to AI forecasting models in low- and middle-income countries.

AI forecasts can be tailored to context-specific agricultural needs, such as identifying optimal planting windows, predicting dry spells or planning pest management. Disseminating those forecasts through text messages, radio, extension agents or mobile apps can then help reach farmers who can benefit. This is especially true when the messages themselves are constantly tested and improved to ensure they meet the farmers’ needs.

A recent study in India found that when farmers there received more accurate monsoon forecasts, they made more informed decisions about what and how much to plant – or whether to plant at all – resulting in better investment outcomes and reduced risk.

A new era in climate adaptation

AI weather forecasting has reached a pivotal moment. Tools that were experimental just five years ago are now being integrated into government weather forecasting systems. But technology alone won’t change lives.

With support, low- and middle-income countries can build the capacity to generate, evaluate and act on their own forecasts, providing valuable information to farmers that has long been missing in weather services.The Conversation

What is AI slop? A technologist explains this new and largely unwelcome form of online content

AI slop refers to low- to mid-quality content—images, videos, audio, text—generated quickly and cheaply by AI tools, often without accuracy. It floods social media and platforms like YouTube, Spotify, and Wikipedia, displacing higher-quality, human-created content. Examples include AI-generated bands, viral images, and videos that exploit internet attention economies for profit. AI slop harms artists by reducing job opportunities and spreads misinformation, as seen during Hurricane Helene with fake images used politically. Platforms struggle to moderate this content, threatening information reliability. Users can report or flag harmful AI slop, but it increasingly degrades the online media environment.

You’ve probably encountered images in your social media feeds that look like a cross between photographs and computer-generated graphics. Some are fantastical – think Shrimp Jesus – and some are believable at a quick glance – remember the little girl clutching a puppy in a boat during a flood?

These are examples of AI slop, low- to mid-quality content – video, images, audio, text or a mix – created with AI tools, often with little regard for accuracy. It’s fast, easy and inexpensive to make this content. AI slop producers typically place it on social media to exploit the economics of attention on the internet, displacing higher-quality material that could be more helpful.

AI slop has been increasing over the past few years. As the term “slop” indicates, that’s generally not good for people using the internet.

AI slop’s many forms

The Guardian published an analysis in July 2025 examining how AI slop is taking over YouTube’s fastest-growing channels. The journalists found that nine out of the top 100 fastest-growing channels feature AI-generated content like zombie football and cat soap operas.

This song, allegedly recorded by a band called The Velvet Sundown, was AI-generated.

Listening to Spotify? Be skeptical of that new band, The Velvet Sundown, that appeared on the streaming service with a creative backstory and derivative tracks. It’s AI-generated.

In many cases, people submit AI slop that’s just good enough to attract and keep users’ attention, allowing the submitter to profit from platforms that monetize streaming and view-based content.

The ease of generating content with AI enables people to submit low-quality articles to publications. Clarkesworld, an online science fiction magazine that accepts user submissions and pays contributors, stopped taking new submissions in 2024 because of the flood of AI-generated writing it was getting.

These aren’t the only places where this happens — even Wikipedia is dealing with AI-generated low-quality content that strains its entire community moderation system. If the organization is not successful in removing it, a key information resource people depend on is at risk.

Harms of AI slop

AI-driven slop is making its way upstream into people’s media diets as well. During Hurricane Helene, opponents of President Joe Biden cited AI-generated images of a displaced child clutching a puppy as evidence of the administration’s purported mishandling of the disaster response. Even when it’s apparent that content is AI-generated, it can still be used to spread misinformation by fooling some people who briefly glance at it.

AI slop also harms artists by causing job and financial losses and crowding out content made by real creators. The placement of this lower-quality AI-generated content is often not distinguished by the algorithms that drive social media consumption, and it displace entire classes of creators who previously made their livelihood from online content.

Wherever it’s enabled, you can flag content that’s harmful or problematic. On some platforms, you can add community notes to the content to provide context. For harmful content, you can try to report it.

Along with forcing us to be on guard for deepfakes and “inauthentic” social media accounts, AI is now leading to piles of dreck degrading our media environment. At least there’s a catchy name for it.The Conversation

Adding more green space to a campus is a simple, cheap and healthy way to help millions of stressed and depressed college students

College students face significant stress from academics, social pressures, and finances, contributing to rising anxiety, depression, and suicide rates. The 2024 National College Health Assessment found 30% of students report anxiety harming academics, with 20% at risk of severe distress. While counseling services have expanded, creating healthier campus environments by increasing green spaces offers another solution. Research, including a Texas A&M study, shows access to greenery, nature views, and walkable paths reduces stress, improves mood, and fosters belonging. Outdoor areas like Aggie Park provide mental health benefits and encourage physical activity, which lowers anxiety and depression. Smaller schools and those with religious affiliations also report better student mental health. Enhancing campus green spaces is a cost-effective way to support student well-being and academic success.

Stress on college students can be palpable, and it hits them from every direction: academic challenges, social pressures and financial burdens, all intermingled with their first taste of independence. It’s part of the reason why anxiety and depression are common among the 19 million students now enrolled in U.S. colleges and universities, and why incidents of suicide and suicidal ideation are rising.

In the 2024 National College Health Assessment Report, 30% of the 30,000 students surveyed said anxiety negatively affected their academic performance, with 20% at risk for symptoms that suggest severe psychological distress, such as feelings of sadness, nervousness and hopelessness. No wonder the demand for mental health services has been increasing for about a decade.

Many schools have rightfully responded to this demand by offering students more counseling. That is important, of course, but there’s another approach that could help alleviate the need for counseling: Creating a campus environment that promotes health. Simply put, add more green space.

We are scholars who study the impact that the natural environment has on students, particularly in the place where they spend much of their time – the college campus. Decades of research show that access to green spaces can lower stress and foster a stronger sense of belonging – benefits that are particularly critical for students navigating the pressures of higher education.

Making campuses green

In 2020, our research team at Texas A&M University launched a Green Campus Initiative to promote a healthier campus environment. Our goal was to find ways to design, plan and manage such an environment by developing evidence-based strategies.

Our survey of more than 400 Texas A&M students showed that abundant greenery, nature views and quality walking paths can help with mental health issues.

More than 80% of the students we surveyed said they already have their favorite outdoor places on campus. One of them is Aggie Park, 20 acres of green space with exercise trails, walking and bike paths and rocking chairs by a lake. Many students noted that such green spaces are a break from daily routines, a positive distraction from negative thoughts and a place to exercise.

Our survey confirms other research that shows students who spend time outdoors – particularly in places with mature trees, open fields, parks, gardens and water – report better moods and lower stress. More students are physically active when on a campus with good walkability and plenty of sidewalks, trails and paths. Just the physical activity itself is linked to many mental health benefits, including reduced anxiety and depression.

Outdoor seating, whether rocking chairs or park benches, also has numerous benefits. More time spent talking to others is one of them, but what might be surprising is that enhanced reading performance is another. More trees and plants mean more shaded areas, particularly during hot summers, and that too encourages students to spend more time outside and be active.

Less anxiety, better academic performance

In short, the surrounding environment matters, but not just for college students or those living or working on a campus. Across different groups and settings, research shows that being near green spaces reduces stress, anxiety and depression.

Even a garden or tree-lined street helps.

In Philadelphia, researchers transformed 110 vacant lot clusters into green spaces. That led to improvements in mental health for residents living nearby. Those using the green spaces reported lower levels of stress and anxiety, but just viewing nature from a window was helpful too.

Our colleagues discovered similar findings when conducting a randomized trial with high school students who took a test before and after break periods in classrooms with different window views: no window, a window facing a building or parking lot, or a window overlooking green landscapes. Students with views of greenery recovered faster from mental fatigue and performed significantly better on attention tasks.

It’s still unclear exactly why green spaces are good places to go when experiencing stress and anxiety; nevertheless, it is clear that spending time in nature is beneficial for mental well-being.

Small can be better

It’s critical to note that enhancing your surroundings isn’t just about green space. Other factors play a role. After analyzing data from 13 U.S. universities, our research shows that school size, locale, region and religious affiliation all make a difference and are significant predictors of mental health.

Specifically, we found that students at schools with smaller populations, schools in smaller communities, schools in the southern U.S. or schools with religious affiliations generally had better mental health than students at other schools. Those students had less stress, anxiety and depression, and a lower risk of suicide when compared with peers at larger universities with more than 5,000 students, schools in urban areas, institutions in the Midwest and West or those without religious ties.

No one can change their genes or demographics, but an environment can always be modified – and for the better. For a relatively cheap investment, more green space at a school offers long-term benefits to generations of students. After all, a campus is more than just buildings. No doubt, the learning that takes place inside them educates the mind. But what’s on the outside, research shows, nurtures the soul.The Conversation
