Medical Marijuana Stats and Facts by State

22. Total sales from legal marijuana in 2020 were nearly $20 billion.


Researchers are unanimous in their assumption on the projected revenue from medical marijuana in the coming years based on 2020 sales. According to data, the US reached almost $20 billion in total sales from medical and recreational marijuana.

More than the number of consumers, the growth in sales is in how many dispensaries are present in the United States in 2020. For example, Oregon, which is the fastest-growing market, has 16.5 dispensaries per 100,000 people.

23. Colorado’s cannabis sales grew by 26%.


There’s little question that the pandemic caused massive disruptions in different businesses and industries. For some, it was disastrous; for others, it was beneficial. The cannabis market was one of those that saw an exponential gain in its total sales.

Proof of this is the medical marijuana statistics in Colorado. Based on the latest records, the state grew its sales by 26%, equivalent to $2.2 billion in revenue in the past year.

24. California’s cannabis revenue grew by 57% from the previous year’s sales.

Medical Marijuana Fun Facts

25. Only 9% of marijuana users will develop and meet all criteria for addiction.

(Brain Facts)

Many people believe marijuana is not addictive. Unfortunately, this is one of those medical marijuana facts and myths that leaves plenty of people confused. Studies show that 9% of people who use marijuana become addicted to the substance.

This figure might seem negligible, but the number goes up to 17% if they were using marijuana in their adolescence. This is because, during this period, the human brain is still developing, which makes it more susceptible to psychoactive substances.

26. Marijuana is less harmful than alcohol.


It’s not one of the most widely known medical marijuana facts, but marijuana is less harmful than alcohol. In fact, researchers found that moderate use of marijuana is less dangerous than any other substance.

Records show that alcohol-induced deaths in the US reached more than 35,000, while no marijuana-induced deaths were on paper.

27. Men and women react differently to marijuana.

(Addiction Center)

There are several facts about medical marijuana circulating the internet, which people can expect because of the legalization issues of marijuana. One of these facts involves the varying physical and mental reactions of men and women to marijuana consumption.

Apparently, men are three times more likely to develop an addiction to marijuana and smoke the substance daily. Further, women may experience spatial memory impairment more than men, while men can display more marijuana-induced euphoria.


Medical marijuana has become increasingly popular in the US because of recent studies that show that cannabinoids have fewer adverse effects than other substances.

Whether these benefits and facts on medical marijuana are universal remains inconclusive because federal law still prohibits the distribution and consumption of marijuana.

These restrictions hinder further studies on the efficacy of the substance. However, the current data should be enough to spike curiosity to conduct studies that may shed additional light on marijuana’s properties and benefits.


Proponents of marijuana usage point out several reasons why the federal government should consider its legalization.

First, most patients who experience chronic pain and nausea have experienced relief from their symptoms because of marijuana.

Second, based on statistics, marijuana has fewer side effects than other substances like opioids.

Lastly, the legalization of marijuana helps decrease prison overcrowding because marijuana possession has a high arrest rate.

Medical marijuana contains chemical compounds that researchers call cannabinoids. THC and CBD are two cannabinoids that appear to respond to the brain’s receptors.

These compounds can block signaling systems within the brain, which may help in epileptic seizures. Despite these promising findings, researchers think the effects and benefits are still inconclusive and that further research is necessary.

However, because marijuana is still illegal on a federal level, conducting studies on the substance is extremely difficult.

Medical marijuana can help patients suffering from several diseases and ailments. It can help people suffering from diseases with symptoms like sleep problems, nausea, vomiting, and loss of appetite.

Despite these many benefits, marijuana is mostly known for its ability to provide relief to patients suffering from chronic pain. In fact, almost three-quarters of medical marijuana patients use the substance to have comfort from chronic pain.

Although marijuana consumption for whatever purpose is still illegal per federal law, despite this restriction, the most recent records show that the US has millions of medical marijuana patients.

To be more accurate, the country has over 4.3 million state-legal medical marijuana patients from 40 different states and US territories. Researchers expect this number to continue to rise because of the increasing number of Americans who suffer from chronic pain.

Every state that legalized marijuana has its own set of laws and policies that define which illnesses qualify for medical marijuana. However, most states approve medical marijuana for cancer, glaucoma, HIV, Crohn’s disease, epilepsy, and multiple sclerosis.

Usually, these illnesses cause patients to experience chronic pain, nausea, vomiting, and loss of appetite. While marijuana doesn’t heal patients from these illnesses, it helps provide relief to patients. 

The income from medical marijuana varies from state to state because of several elements that affect sales. Consequently, these factors, such as the number of consumers and the dispensaries, affect the state’s income from medical marijuana.

Based on the most recent data from states that legalized marijuana, California had the highest sales amounting to $4.4 billion, with total tax revenue of $1.03 billion.

Individuals who consume medical marijuana exhibit side effects. Primarily, biological and sociological differences explain the different side effects. Therefore, it makes sense for researchers to consider other possible effects and benefits of medical marijuana based on sex.

According to available data, women benefit more from medical marijuana in general because men are three times more likely to become addicted to the substance. This is because, unlike women, men exhibit more extraordinary cannabis-induced euphoria. 

Most dispensaries and researchers categorize marijuana into three different types – cannabis sativa, cannabis indica, and hybrid. The cannabis sativa has a low CBD and high THC count, which produces psychoactive effects.

This kind of medical marijuana is best for countering anxiety and depression. On the other hand, cannabis indica possesses a high CBD and low THC count. Usually, it doesn’t produce any psychoactive effects.

The cannabis indica is best for people struggling with mental and muscle relaxation, nausea, and sleep. On the other hand, the hybrid type has three categories – sativa dominant, indica dominant, and even hybrids.

While the effects of medical marijuana depend on the levels of CBD and THC present in the product, medical marijuana statistics show that some people experience mellowing effects after taking cannabis sativa.

This shouldn’t be a cause for alarm since the impact of medical marijuana varies from person to person.
