Cannabis Legalization Drives Innovation, Raises Health Concerns
Cannabis legalization is driving innovation, but much of it focuses on commercial products rather than patient health. New research highlights gaps between market growth and medical evidence.

Cannabis legalization
Innovation in health care saves lives. But not all health innovations have enough evidence to actually benefit patients.
Barriers to innovation are often higher in illicit or restricted markets, including cannabis, stem cells and cryptocurrencies. Researchers face higher costs, limited access to raw materials and data, and stricter regulations.
Cannabis illustrates a particularly confusing tension between regulatory restrictions on one hand and research and innovation on the other.
While the U.S. federal government still classifies cannabis as having “no accepted medical use,” many states have legalized it for medical or recreational use. Meanwhile, the Department of Health and Human Services obtained a cannabis-related patent in 2003 covering potential medical uses of cannabis compounds for protecting the brain from damage or degeneration. The patent was exclusively licensed for commercialization.
Research and innovation on cannabis can take many forms. Clinical trials may study cannabis products as medical treatments, the effects of cannabis on its users, or factors related to abuse and dependence. Meanwhile, cannabis-related patents can be filed for wide-ranging purposes, such as chemical formulations, methods for production or new consumer products like edibles, beverages or vaporizers.
But do these innovations actually benefit consumers and patients?
We are economists studying how institutional changes affect innovation in different markets. Our recently published research found that legalization of recreational cannabis use appears to spur innovation, but primarily in ways that expand commercial opportunities rather than scientific understanding or health benefits for patients.
Cannabis’ evolving legality in the US
Cannabis is a plant that contains chemical compounds called cannabinoids. One such compound, tetrahydrocannabinol, or THC, produces psychoactive effects, while another compound called cannabidiol, or CBD, is often used to relieve anxiety and pain. However, there has been insufficient evidence on how effective cannabis products are in treating medical conditions, as well as a lack of consistent medical and dosing guidance.
At the federal level in the U.S., cannabis has been classified as a Schedule I drug for over a half-century. This classification indicates that the federal government considers cannabis to have a high potential for abuse and no accepted medical use.
As a Schedule I drug, there are significant restrictions on cannabis research. Researchers who seek to conduct cannabis-related clinical trials must obtain approval from both the Food and Drug Administration and the Drug Enforcement Administration, a process that can take over a year. They are also limited to using select varieties of cannabis obtained from federally authorized cannabis suppliers, and are generally prohibited from studying products available in state-authorized markets.
There are ongoing pushes to relax these restrictions. Meanwhile, cannabis has been legalized to varying extents in many states. California became the first state to pass a medical cannabis law in 1996, allowing qualified patients to grow, possess and use cannabis for medical purposes. Many states followed suit in the late 1990s and early 2000s. As of June 2025, 40 states allow medical cannabis use.
A number of states also allow recreational or nonmedical cannabis use among adults, which is regulated in similar ways to alcohol. Colorado and Washington enacted the first recreational cannabis laws in 2012, and there are 24 states that permit adults to use cannabis recreationally as of January 2026.
Altogether, the legal landscape for cannabis in the U.S. has varied considerably across states and over time. States with more permissive laws can lower the costs of medical research and product development with cannabis, even if federal drug scheduling continues to restrict access. For instance, one group of Washington State University researchers asked participants to independently purchase and smoke cannabis from a legal dispensary before returning to their lab for study.
State legalization and cannabis innovation
To systematically examine how state legalization affects cannabis-related innovation, we compiled and analyzed datasets tracking cannabis-related clinical trials and patent applications.
We distinguished different types of cannabis-related innovation. Specifically, we categorized cannabis-related clinical trials based on whether they focused on its potential as a treatment, its usage and effects, or its role in drug abuse. Similarly, we categorized cannabis-related patents based on whether they focused on chemical compounds, medical uses, methods or products.
We also assessed public health concerns across three measures: patents explicitly involving THC; patents with a high risk of misuse; and patents targeting consumers directly, such as high-potency formulations, edibles or vaporizers.
Then, we compared changes in cannabis-related innovation over time in states that legalized cannabis earlier with those in states that did so later or not at all. We measured innovation by counting the number of cannabis-related clinical trials and patent filings. We distinguished between medical and recreational legalization to assess how different policies affect innovation.
Overall, we found that when states legalize cannabis for recreational use, cannabis-related patents increase – but mostly in commercial-oriented areas rather than health-focused ones. Patents were concentrated in market-oriented innovations like cultivation equipment and consumer products, rather than in clinical or science-based research. We also found some evidence that these innovations may raise public health concerns.
Legalization did not result in meaningful increases in clinical trials. This suggests that barriers to cannabis-related clinical research – such as limited access to research-grade cannabis, limited funding and stigma around working with a federally controlled substance – remain substantial.
Gaps between research and product
As 420 – signifying April 20, a day celebrating cannabis culture – approaches each year, public attention turns toward the legal status of cannabis.
The legal landscape has evolved rapidly over the past few decades, and further changes are in the pipeline. Both the Biden and second Trump administrations have made efforts to reclassify cannabis as a Schedule III substance, which would indicate that it has an accepted medical use and low-to-moderate potential for dependence.
These reevaluations of the legality of cannabis come at a critical time. There has been an explosion of recreational cannabis products in recent years, including increasingly potent strains and a wider variety of ways to use cannabis. Meanwhile, critical research on the health and safety of cannabis use has lagged due to heavy restrictions accompanying Schedule I status.
This gap between medical research and product innovation can have significant public health consequences. The 2019 to 2020 outbreak of lung injuries related to e-cigarette or vape use was linked partly to the use of unregulated or illicit cannabis vaping products. These harms highlight the risks of allowing product innovation for controlled substances to outpace scientific understanding.
Policies that significantly reduce obstacles to clinical research can in turn help close the widening gap between cannabis markets and addressing their public health implications.

How Invasive Pests Spread and How You Can Help Stop Them
(Feature Impact) Invasive pests can hide in places you’d never expect, and once they spread, they can destroy the trees, plants and food people rely on every day. These pests pose a serious threat to agriculture, forests, ecosystems and the food supply. Many invasive species cannot travel far on their own; instead people unknowingly move them from place to place.
According to the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service, invasive pests hitchhike on everyday items such as plants, produce, firewood, vehicles and outdoor equipment. That makes many common activities – from traveling and online shopping to camping and gardening – potential “pathways” for invasive pests to move and reach new areas. Understanding these pathways is the first step to stopping pests before they spread.
Traveling Abroad
When you travel abroad and return from another country, the agricultural items you bring back can introduce new invasive pests into the U.S. and threaten crops or trees that have no natural defenses against them. Even harmless-looking fruit, seed packets or souvenirs made with plant materials can carry pests such as fruit flies and diseases like citrus canker. That’s why it’s critical travelers declare food, plants and other agricultural products when entering the country from abroad.
Shopping Online
Just because you can order seeds and plants from sellers around the world, it doesn’t mean those items are legal or safe to import. In fact, some invasive snails and plant diseases have entered the U.S. this way. Many agricultural products from overseas require permits, inspections or special paperwork before they can enter the country. Buyers should check where an item ships from, learn the import requirements before purchasing and make sure sellers follow all labeling and shipping rules.
Partaking in Outdoor Activities
When you spend time outdoors hiking, camping, hunting or fishing, you could inadvertently spread invasive species. For example, transporting firewood from one location to another can spread tree-killing insects, such as the emerald ash borer, which can live inside the wood and emerge later in a new area. The safest choice is to buy or use firewood where you burn it. Additionally, clean all outdoor clothing, gear, equipment and vehicles before leaving an area.
Moving Outdoor Equipment
When you move to a new home, your move can create another opportunity for invasive insects to travel. Before relocating patio furniture, grills, trailers or lawn equipment, inspect and clean them carefully. Look for insects, plant debris and egg masses like spotted lanternfly egg masses, which can blend into outdoor surfaces and look like smears of mud or clumps of dirt. A few minutes of checking and cleaning before you move can help prevent pests from invading your new neighborhood.
Invasive pests cost the U.S. billions of dollars every year and damage forests, farms, parks and backyards. Stopping invasive pests starts with simple steps anyone can take: checking what you pack, clean, move and buy. When everyone does their part, fewer pests spread and communities stay healthier and more resilient.

Invasive Pest Protection Checklist
- Declare all food, plants and agricultural items when returning from another country.
- When ordering items online, check where the products ship from and verify U.S. import rules before buying.
- If you’re camping, buy firewood where you plan to burn it. Clean clothing, gear and vehicles before leaving.
- Before moving to a new home, inspect outdoor furniture and equipment, looking closely for egg masses or insects.

Get Your Kids Ready to Go Back-to-School with Affordable Health Coverage
Once school starts, life moves fast. There is homework, practices, permission slips, and early mornings. Before the calendar fills up, take a moment to make sure your child has affordable health coverage for the year ahead.
Get Your Kids Ready to Go Back-to-School with Affordable Health Coverage
(Feature Impact) Once school starts, life moves fast. There is homework, practices, permission slips, and early mornings. Before the calendar fills up, take a moment to make sure your child has health coverage for the year ahead.
Free or low-cost health coverage is available through the Children’s Health Insurance Program (CHIP) or Medicaid in your state for eligible individuals. With health coverage, your kids and teens can get the care they need to stay healthy and do well in school.
Think your family might not qualify? You might be surprised. Many families may qualify for coverage without realizing it! Eligibility varies by state and is based on family income and household size. In most states, children up to age 19 from a family of four earning up to $80,000 per year may be eligible. In some states, eligible children can still qualify if family income is even higher.
Getting your child covered helps you get them the health care they may need. When a child is sick, the right medicines help them get back to school. If a child has a tough time focusing, there are supports to help. If your child does not see as well as other children, these programs cover glasses. Healthy kids are confident kids, who are ready to participate in every opportunity inside and outside the classroom!
Why Health Coverage Belongs on Your Kids’ Back-to-School List
Having health coverage can help families, like yours, to send your kids and teens off to school ready to learn. Depending on the program and a child’s individual needs, Medicaid and CHIP can provide eligible kids up to age 18 (Medicaid) or 19 (CHIP) with a range of services to support their health all year long, such as:
- Annual checkups and school physicals to prepare children to learn, play, and participate.
- Preventive care to identify health needs early and keep children healthy throughout the year.
- Dental care to help prevent tooth aches, cavities, and missed school days.
- Vision and hearing services to support learning and classroom participation.
- Mental health care to support emotional well-being and school success.
- Prescription medications and treatment to help manage symptoms and stay on track.
- Specialized services for children with disabilities to support growth and learning.
How to Apply
You can apply for Medicaid and CHIP in many ways:
- By phone
- By mail
- In-person through your state’s Medicaid or CHIP office
- Or find your state’s information online at InsureKidsNow.gov/coverage.
Act now to get your child covered before they need health care. Enrollment for these programs is open year-round, meaning families do not have to wait for a specific time of year to get covered.
Once enrolled, coverage must be renewed every twelve months, so it is important to keep your address, email, and phone number up to date with your state Medicaid or CHIP office to avoid missing important renewal information. Visit InsureKidsNow.gov or call 1-877-KIDS-NOW (1-877-543-7669) for more information.

Strong at Every Age: How Women Can Help Combat Muscle Loss
Combat Muscle Loss: Aging is inevitable, but losing muscle and mobility doesn’t have to be. Consider these tips to help women protect their muscle health.
Strong at Every Age: How Women Can Help Combat Muscle Loss
(Feature Impact) Aging is inevitable, but losing muscle and mobility doesn’t have to be. For many women, maintaining strength, independence, energy and mobility are top priorities as they get older, particularly as they deal with the mental and physical responsibilities that come with working, caregiving, keeping up with friends, hobbies and enjoying an active lifestyle.
In fact, 58% of women in the United States are actively focused on staying healthy as they age, according to a recent survey commissioned by Viactiv, a line of award-winning supplements for women known for their unique formats and flavors. However, 73% of respondents weren’t aware of sarcopenia, or age-related muscle loss. According to the “International Journal of Women’s Health,” age-related muscle loss often begins between ages 30-35, with women losing 3-8% of their muscle mass per decade and increasing to 5-10% loss per decade after age 60.
Hormonal changes, decreased activity levels, stress, poor sleep and inadequate nutrition can all contribute to the decline in muscle, which can also negatively impact balance, bone health, metabolism, posture and everyday mobility.
Yet, despite 70% of women reporting some level of concern about muscle loss, 54% are unsure how to protect their muscle health.
“Women want to stay strong, active and independent as they age, but many are getting mixed messages about what actually supports long-term muscle health,” said Dr. Tania Elliott, a dual board-certified physician in internal medicine. “A lot of women are already making healthy choices like walking and staying active, which is a great start. However, maintaining muscle health really requires a more complete approach, and one that starts earlier than most women think, which is in your 30s.”
Prioritize Strength Training
Many women report barriers such as lack of time (15%), feeling overwhelmed (23%) or simply not enjoying exercise (23%). The key is finding realistic, sustainable habits. While walking and cardio exercise aid in heart health, which 58% of survey respondents report already engaging in, strength training is one of the most effective ways to preserve and build muscle as you age. Still, just 34% of women report doing strength or resistance training.
You don’t need an intense fitness regimen to support healthy aging. Aiming for at least two strength-focused workouts a week – lifting weights, using resistance bands, practicing weight-bearing yoga or doing bodyweight exercises like squats and pushups – that target major muscle groups can help maintain muscle health. The goal is to fatigue your muscles during sets so they build.
Fuel Muscles with Proper Nutrition
Exercise is only part of the equation. Muscles also need proper nutrition to recover and stay strong. Protein plays a critical role in maintaining muscle mass, especially as women age. Incorporating high-quality protein throughout the day, such as eggs, Greek yogurt, fish, lean meats, beans, lentils, nuts and seeds, may help support muscle repair and overall strength.
Support Healthy Aging with Supplements
In addition to a balanced diet and exercise, some women may consider supplements that support healthy aging and energy production, including CoQ10, which is a naturally occurring antioxidant that helps cells produce energy. According to research published in “The Journal of Nutrition, Health and Aging,” because muscles require significant energy to function, CoQ10 shows potential for managing sarcopenia by improving mitochondrial function and reducing oxidative stress.
An option like Viactiv CoQ10 Cardio Complete, available in a tasty fruit-flavored chew, can help support heart health, muscles, nerve function and daily energy. Enhanced with vitamins D3 and K2, it provides daily essential nutrition for women without the need to swallow a large pill.
Practice Healthy Habits
Muscle health is influenced by more than workouts. Sleep, stress management and daily movement all play important roles. Adopting some simple habits, including prioritizing quality sleep, stretching regularly, staying properly hydrated, reducing sedentary time throughout the day and practicing stress-management techniques, like yoga, meditation or deep breathing, can help aid in healthy aging, including maintaining muscle.
The earlier women begin prioritizing muscle health, the better positioned they may be to maintain strength and mobility as they age. Visit Viactiv.com for more information and resources to help combat muscle loss.
