A Decade of Change: Cannabis Legalization Then and Now

The last ten years have seen a big change in the United States. The topic of cannabis being legal went from being a taboo to a normal thing1. Back in 2012, Colorado and Washington were the first ones to say it's okay to use marijuana just for fun. This made other states think, and now 23 states allow people to use marijuana for fun. And 38 states let people use it as a medicine1. This is a big change from before, when the government saw cannabis as bad as heroin and LSD1.


This change has brought a really big business in Colorado. The cannabis industry there is worth about $2 billion every year2. Also, people in states where cannabis is allowed use it more. They use it 24% more often than those in places where it's not allowed2. But, even though more and more people agree with using cannabis, the government at the very top hasn't said it's okay all over. So, there's a mix of different laws across the states, and these laws are always changing.

Key Takeaways

  • Recreational marijuana use is now legal in 23 states, and medical use is allowed in 38 states.

  • Colorado's cannabis industry is valued at $2 billion per year, and residents of legal states use marijuana 24% more frequently.

  • The federal government still classifies cannabis as a Schedule I drug, despite growing public support for legalization.

  • Lawmakers face ongoing challenges in regulating the cannabis industry and addressing social equity concerns.

  • The next five years may see further progress in federal cannabis reform, though the timeline remains uncertain.


Introduction to Cannabis Legalization

Cannabis, also known as marijuana, has faced many challenges through history3. It was illegal in many places for a long time, including the U.S. Yet, in recent times, approaches have changed. A movement for cannabis reform has made it legal in more areas for medical and/or recreational use.


History of Cannabis Prohibition and Reform Movements

3 By the mid-1930s, every U.S. state had laws against cannabis under the Uniform State Narcotic Drug Act3. The Marihuana Tax Act of 1937 was a big step in national regulation3. Then, in 1970, the U.S. declared cannabis illegal for all uses with the Controlled Substances Act3.


The change began in 1996 when California allowed medical cannabis despite federal laws3. By 2016, many states had followed, legalizing medical use3. In 2012, Colorado and Washington became the first to legalize it for fun. Since then, more places have joined them, even if U.S. federal laws still say no.


Rationale and Objectives Behind Cannabis Legalization

The goals of letting cannabis be used legally include keeping it away from kids, cutting off money to illegal groups, and ensuring safety through controlled access for adults4. Research has shown more older adults in the U.S. are using cannabis lately, which argues for legal, controlled access4. In Canada, studies from 1985 to 2015 suggested changes in how cannabis is used. And in Ontario, Canada, studies from 2012 to 2017 looked at cannabis use during pregnancy.


4 In California, researchers looked into driving while under the influence of cannabis. They found that from 2005 to 2017, people with depression changed how they view the risks of cannabis4. And in 2002, 2008, and 2009, they checked on the cases of cannabis addiction in veterans. This valuable research helps shape the reasons for making cannabis legal. The goal is to keep the public safe while giving adults controlled access to the drug.

"The goal of cannabis legalization is to prevent youth access, cut illegal profit, and ensure safety through controlled access for adults."

Global Landscape of Cannabis Legalization

The world is changing fast when it comes to cannabis. Many countries and areas are now allowing the drug for medicine or fun5. In the US, 38 states and Washington, D.C. let people use cannabis for medical reasons. And 23 states and D.C. allow its recreational use6. Places like Canada, Uruguay, and some parts of Europe and South America have opened up to cannabis too, each with its own rules6.


Countries and Regions that Have Legalized Cannabis

Canada made cannabis legal for adults to buy, carry, and use for enjoyment in 20187. Many Canadians have tried it, about half, actually7. In the US, California set the trend by letting people use it for medicine in 1996. Washington State and Colorado then made it legal for fun in 20126.


Variations in Legalization Approaches and Policies

Each place has its own way of doing this. They have different rules on how much you can grow, sell, and use. Canada aimed to protect young people, reduce crime, and keep the public safe7. In the US, more and more people support legal cannabis. This change in attitude shows in national surveys6.


Even though many places are making cannabis legal, we're still not sure about its medical benefits. We need more studies to find out if it's really helpful6. Also, making cannabis legal might cause some people to use it too much. This could become a problem over time6.

"The global landscape of cannabis legalization is rapidly evolving, with a growing number of countries and regions around the world moving to legalize the drug for medical and/or recreational use."

With more and more places embracing cannabis, officials need to handle a lot of important issues. These involve regulations, health impacts, and how it affects society. They must make careful decisions to have a positive result576.


Impact on Consumption and Use Patterns

The legalization of cannabis has changed how much it's used in places that allowed it8. People in these areas now use cannabis 24% more often than in places where it's still illegal8. But, using more cannabis hasn't caused more problems or bad behaviors8.


Changes in Cannabis Use Prevalence Before and After Legalization

Looking at national surveys, we see how cannabis use has varied over time9. Use went down in periods from 1979–1992 and 2001–2006. But, it went up in 1992–2001 and 2006–20169.


This research also found that laws allowing medical marijuana were linked to how much people used it. But, laws for just having fun with marijuana didn’t show this connection.


The study also discovered that the year you were born can affect if and how much you use marijuana. For example, those born between 1954 and 1972 used less over time. But those born between 1972 and 1984 used it more, before it dropped again for those born between 1984 and 20039. This shows how laws and rules really matter, especially for young people.


After Canada made cannabis legal in 2018, there was a change in where people got it from10. Legal places to buy cannabis have become more popular than illegal ones10. Now, from 2018 to 2020, the number of people getting cannabis legally has jumped from 23% to 68%10.


But, Canada's different areas have their own rules on where you can buy it, use it in public, and how you can grow it at home. These rules lead to some places using cannabis more than others10.

"The historical trends of marijuana use were shaped by state laws and regulations, with implications for attitudes and behaviors, particularly among adolescents and emerging adults."

The evidence we have shows that making cannabis legal has had big, varied effects on how much it's used. There's been an overall increase, but why and what this means for health and public well-being is still being studied and debated9810.

Regulatory Frameworks and Market Dynamics

The legalization of cannabis has led to new rules and ways to handle its sale and distribution. As this new industry grows, people making the rules and those involved are figuring out how to make everything work well. They are working on the best ways to grow and sell cannabis, deliver it to people, and set fair taxes.


Legal Cannabis Supply Chains and Distribution Models

Moving from selling cannabis illegally to doing it legally requires careful planning. In places like Colorado, the legal cannabis business is now worth $2 billion each year11. To make sure products are always safe and available, they have set up strict rules for who can grow, process, and sell cannabis. They also use technology to track where each item comes from until it's sold11.


How cannabis is sold can be different from one place to another. Some areas let the government control everything, like selling liquor. Others let businesses compete, offering more choice to people. For example, in Canada, both government-run and private cannabis stores are allowed, giving customers many options12.


Taxation and Revenue Generation from Legal Cannabis Sales

Legalizing cannabis lets governments raise a lot of tax money from its sales. In the U.S., states with legal cannabis use different types of taxes and fees11. The money from these taxes goes to different state needs, like schools or better roads11.


Taxing cannabis at the right level is crucial. Governments want to make sure they earn enough without making legal prices too high. This way, they can fight illegal selling by making the legal market a better choice for buyers11.

The boxes move along the conveyor belts through different rooms, where they are sorted by strain and quality and packaged into smaller containers. In the final room, workers carry the finished products to a display area where customers can see and purchase them.
"The regulation of cannabis was described as touching every aspect of society, with a focus on balancing appropriate restrictions to minimize harm with providing adult access to a regulated supply to reduce the illicit market's social harms."11

Cannabis Legalization Then and Now

A decade ago, Colorado and Washington led the way by making cannabis legal for adults to use. This was a big deal for the U.S. and the rest of the world. Over the years, more places have followed, deciding to allow the use of cannabis for medical reasons or by adults13. This has led to the growth of a legal cannabis industry and fueled many debates about how to manage these new laws.


The U.S. has seen big changes in cannabis laws. California started it by approving medical cannabis in 1996. By 2016, most states had done the same13. In 2012, Washington and Colorado set a new benchmark by allowing adults to use cannabis for fun. This move led many other states to head in the same direction13. Now, 37 states let people use cannabis for medical reasons, and 21 states plus D.C. permit it for recreational use14. And more Americans than ever, 52%, support making cannabis legal, compared to only 12% in 196914.


Across the globe, more and more countries are legalizing cannabis15. Canada, for instance, has seen a growing number of people using cannabis since the time it became legal in 2018. The Canadian cannabis industry has grown a lot too, earning over $10 billion by 202315.


The journey to legalizing cannabis has not been easy. Policymakers are trying to figure out how to protect public health and ensure fairness as the industry grows14. These efforts are influencing not just local laws but also how countries work together in areas like trade and tourism14. The story of cannabis legalization is far from over. It will remain a big topic for countries around the world as they navigate these changes.

"The legalization of cannabis has been a complex and often contentious process, but one that has the potential to bring about significant social, economic, and public health benefits if implemented thoughtfully and responsibly."

Public Health Implications

The legalization of cannabis has stirred up major concerns in public health. These mainly focus on the effects on young people. Some studies show that overall cannabis use goes up when it's legalized. But this doesn't always mean there's more misuse or other negative outcomes1617.


Effects on Youth and Adolescent Usage

Adolescents' use of cannabis is still a big issue. In 2021, about 7.1% of 8th graders, 17.3% of 10th graders, and 30.5% of 12th graders admitted to using marijuana in the past year16. Plus, most 12th graders who used it, chose to vape as their way of taking it16. Though usage rates differ among states, the risk to young people's health is a key worry16.


Potential Benefits and Risks to Public Health

The debate around legal cannabis points out possible good and bad effects. For example, using it for medical reasons shows some positive results17. However, allowing its recreational use seems to have led to more bad events. States like Colorado saw more ER visits, car accidents, and deaths. In Canada, severe intoxication cases among kids climbed since it became legal in 201816.


Children under six are facing more cannabis exposures, with most cases in states that have legalized it. This shows the clear need for wider health protection measures16.


As more areas consider cannabis legalization, health concerns will keep being studied and discussed18. Both policymakers and health experts have to weigh the pros and cons to make sure everyone's health is protected. They especially have to watch out for young people.

Show the impact of cannabis legalization on youth by depicting two contrasting scenes - one of a group of young people engaging in healthy activities like sports and academic pursuits, and another of the same group engaging in potentially harmful behavior like smoking marijuana or being arrested for drug-related offenses. Use color and composition to highlight the differences between the two scenes and convey a message about the importance of responsible cannabis use among young people.
"The legalization of cannabis has raised significant public health concerns, particularly regarding its impact on youth and adolescent usage."

Social and Criminal Justice Impact

The legalization of cannabis has changed how the law handles drug crimes. This has happened mainly in places where cannabis is now legal. For example, over 30 states in the U.S. allow it for medical use. Eleven states and Washington D.C. also permit it for fun19. Colorado and Washington State acted first to make recreational cannabis legal. This was in late 2012. Oregon joined them in late 201419.


There are mixed views on how cannabis legalization affects crime. Some research claims that areas with cannabis shops see more crime. But, there are also studies that show no real change in crime or even lower crime rates19. After recreational cannabis was allowed in Oregon, some crimes went up a lot. These include thefts from cars and homes. The evidence also points to more serious crimes in Oregon compared to states where cannabis is not yet legal19.


Changes in Cannabis-Related Arrests and Incarceration Rates

Not arresting people for cannabis has been a big win since it became legal. In 2018 in the U.S., there were over 663,000 arrests linked to marijuana. Most of these cases involved only possessing marijuana, over 608,00020. The cost of each of these arrests could go as high as $5,000. And it costs around $30,000 to $35,000 a year to keep someone in jail. So, not making these arrests could save a lot of money for the legal system20.


Social Equity and Restorative Justice Initiatives

The move to legalize cannabis has also highlighted how harsh drug laws have hit some groups harder. In the U.S., Black people are about four times more likely than Whites to be arrested for marijuana. In some areas, this difference is even starker, with Black people up to eight times more likely to be arrested20. To make things right, some places are working on programs that help those who were unfairly hurt by past drug laws.


When Canada made cannabis legal in 2018, youth crime related to the drug went down a bit. But, to see the bigger picture on how legalizing cannabis affects all society, more information is needed. Across the U.S., more and more people are okay with the idea of legalizing marijuana. In 2019, about 66% of Americans thought it was a good idea. This includes a majority of Democrats and Independents, and even half of Republicans20.


These steps toward legalizing marijuana suggest it could help correct old wrongs and improve how we deal with drug issues. But, there is still a lot to discuss and figure out about how to do this well192021.


Economic and Industrial Developments

The rise of the legal cannabis market is making big waves economically22. This sector has grown so much that it now provides about 250,000 jobs. This is more than four times what the coal industry offers22. Experts say that if the US fully legalizes cannabis, it could bring in huge tax money and create 1.6 million new jobs22.


Growth of the Legal Cannabis Industry

Legal cannabis sales are booming, especially in places like Colorado. There, it's a $2 billion per year affair22. In Oregon, sales hit $89 million in a single month, up by 45% from the previous year22. Even during the pandemic, Illinois had its second-best month selling cannabis in April, topping $37 million22.

In Canada, cannabis companies are valued much higher than US firms22. This shows the US market has room to grow. For instance, Canopy Growth has a plan to buy Acreage Holdings for $3.4 billion once cannabis is legal nationwide22.


Job Creation and Entrepreneurial Opportunities

Thanks to legal cannabis, there are many new jobs and business chances. Everything from growing to selling weed is now a major employment sector22. It's especially significant because now more Americans work in cannabis than coal22.


The weed business is not just about jobs; it's a chance for new companies, too23. By 2030, it could make over $65 billion, offering many chances for growth23. As more states approve cannabis for medical and fun use, more jobs and businesses will pop up24.

"The cannabis industry has become a significant source of employment, now employing nearly 250,000 full-time jobs, more than four times the number of coal industry workers in the country."

Cannabis Research and Innovation

The legalization of cannabis has sparked a big increase in research and new ideas, especially in medical cannabis15. Places like the University of Colorado Boulder are studying how cannabis might help with pain, anxiety, and fighting cancer15. The legal change has also pushed forward on new ways to use cannabis and new cannabis-infused products.


Advancements in Medical Cannabis Research

Before, getting cannabis for research was tough because only the University of Mississippi could grow it for science25. But, things changed in August 2021. The DEA now lets any qualified group grow cannabis for study25. This move came from a big demand to learn more about cannabis and its potential health benefits25.


Government-backed research had mainly looked into marijuana's bad effects. But lately, some studies show there might be good sides too, like easing inflammation, helping with epilepsy, and mental health issues25. This change in focus might speed up medical cannabis approval by showing its benefits and safety through more detailed studies25.


Product Development and Emerging Cannabis Technologies

The legal cannabis market is creating new products and ways to use them. Now, people can choose from a variety of cannabis-infused products, from foods and creams to high-tech inhaling devices and skin patches15. This broad choice meets different needs and tastes, offering more than just the usual ways to use cannabis.


Additionally, the cannabis industry is seeing new farming methods for better quality and quantity and smart tools to understand what customers like and trends in the market15. These new developments in technology and product offerings are making the cannabis market better in terms of quality and options, and they help the market grow overall.

"The policy change could help remove obstacles to marijuana legalization by facilitating more thorough clinical studies, potentially leading to more widespread approval of medical marijuana."25

The cannabis field is evolving fast. The mix of research, new ideas, and better products is key to its future success. This mix aims to show the full value of cannabis for fun and health152526.


Policy Challenges and Debates

The issue of cannabis legalization brings many hurdles, especially in making and applying laws. Areas struggle with keeping cannabis products safe, stopping them from going to illegal sellers, and dealing with driving under its influence27. There are also big discussions about how much to legalize. Some suggest only for health reasons, not for fun.


Ongoing Challenges in Cannabis Regulation and Enforcement

How much marijuana costs and the taxes on it are big talks in Canada27. Lessons from dealing with alcohol and tobacco help set rules for marijuana use27. In Maine, sales of medical marijuana and its items were tracked in 201627. Oregon and other states started special taxes on marijuana27. The strength and cost of cannabis products change in new markets, like in Washington state. This affects how many people enter drug treatment for the first time27.


Debates on Recreational vs. Medical Use

From 2001-2002 to 2012-2013, more people in the U.S. developed problems with marijuana use27. A big study looked at the link between bad car accidents and using cannabis27. Since the U.S. allowed cannabis, more young people are using vaping and edible products27. There's also talk about making marijuana weaker to lower risks27.


What people think about making marijuana legal has changed a lot in ten years. Now, 53% support it while 44% don't, up from just 32% supporting it in 200628. Many want it legal for health reasons (41%) or because they think it's no worse than other drugs (36%)28. But, 43% of those against it worry it's harmful for society and individuals, and 30% think it's just too risky28.


Research shows that taxing alcohol more can cut down on its abuse and problems27. Making alcohol pricing not too low is seen as the best way to prevent cancer27. Policy changes on drugs in California also affected crime rates27. Looking into how marijuana laws deal with someone's past drug issues is also important27.


Learning about the health effects of cannabis affects the rules we make27. We know using cannabis for fun can have bad health results27. There's a link between how well someone does in school and how they can get marijuana27. The number of people having problems from using marijuana has changed in the U.S. over time27. We've also looked into how the marijuana market in the U.S. was before it was totally legal27.

"Marijuana is a complex issue, with valid concerns on both sides of the debate. Policymakers must carefully weigh the potential benefits and risks to public health and safety as they navigate the path forward."

International Perspectives and Trends

In recent years, countries around the world are making big changes in their cannabis laws. More places are choosing to make the drug legal29. Legalizing cannabis used to be quite uncommon. But now, many places are opening up to the idea. They are creating rules that let people grow, sell, and use cannabis products.


Global Shifts in Attitudes and Policies Toward Cannabis

Today, a lot of adults in different countries think it's okay to use cannabis either for fun or because it helps with health issues30. This change in thinking has led to new laws in places like Canada, Uruguay, and some U.S. states. These places are the first to allow adults to use cannabis for fun without a strict medical reason31.


As more places join in, the whole world's view on cannabis is changing. It's becoming more common and accepted.


Implications for International Trade and Tourism

The move to legalize cannabis is changing how countries do business and attract tourists. Some places aim to be leaders in the cannabis market. They are building complex systems to grow, sell, and create new cannabis products29. This is also affecting where people choose to travel. Some areas are now more popular because of the chance to try cannabis legally, which helps the cannabis industry to grow even more.


The way the world sees and deals with cannabis is changing a lot. As this trend continues, it will affect not only new laws but also trade and travel. The future of the cannabis industry worldwide is taking shape293130.


Future Outlook and Emerging Issues

The cannabis landscape is changing, offering both chances and challenges. More places are looking into making cannabis legal for medical or fun use. This trend towards cannabis legalization is likely to keep growing32.


The cannabis industry is facing new issues that will affect the way we legalize it. These issues include making sure the products are safe, preventing driving when impaired, and finding the right balance between fun and medical use33.


Potential for Further Policy Reforms and Legalization

The path to future cannabis legalization will be shaped by debates, changes in the market, and how society thinks. The support for legal cannabis has grown a lot, especially in the U.S. where 64% were in favor in 2017, up from just 12% in 196933.


Cannabis for medicine is becoming more accepted too. About 17% of users see themselves as needing it for medical reasons. So, the push for legal access to cannabis is only getting stronger33.


Emerging Trends and Challenges in the Cannabis Landscape

New trends and problems are arising in the cannabis industry. For example, Cannabis Use Disorder (CUD) is a concern, affecting 1.5-2.5% of adults and 3.0% of teens in the U.S33..


Another issue is the risk of driving high. It's been found that more cannabis users are involved in serious accidents. This needs serious attention from regulators33.


The cannabis landscape is evolving. Everyone, from policymakers to the public, has a role to play. We must address the new trends and challenges wisely. This way, we can achieve a future where cannabis use is safe, legal, and meets the growing demand3332.

"The future of cannabis legalization will likely be shaped by ongoing policy debates, market dynamics, and societal shifts."

Conclusion

The past decade has seen a big change in how we view drug policy and health thanks to legal cannabis35. Around 55 million Americans have used marijuana in the last ten years. Eleven states took away the charges for having small amounts for personal use35. While the national law still bans marijuana, many places have made it okay for fun and medical use36.


Legal marijuana has brought in a lot of money for states. In 2023, those places made $4.2 billion from taxes36. The weed business is booming. The top marijuana fund, AdvisorShares Pure US Cannabis ETF (MSOS), has over $1 billion in investments36. But, legalizing cannabis is still tricky. There are many issues with how to control and make sure the laws work. Plus, people are still talking about whether it's best for fun or health reasons35.


As time goes on, we're figuring out what legal weed means for us. There are good points and bad points to think about37. Most grown-ups in the U.S. think weed should be legal37. What happens next will depend on what the public wants, rules made, and what we keep learning about weed. In the end, the talk about making weed legal is a very important, changing topic we will keep talking about for a long time.
