What Is Medical Marijuana?

Medical marijuana, derived from the Cannabis sativa plant, contains over 100 unique chemical compounds known as cannabinoids, which include tetrahydrocannabinol (THC) and cannabidiol (CBD). THC is responsible for the psychoactive effects, while CBD provides therapeutic benefits without a "high". The use of marijuana as medicine dates back to 2900 B.C., and modern research has found numerous medical applications for it. The distinction between "regular" and medical marijuana primarily lies in its usage and legal definitions, with medical marijuana being used for symptom alleviation and dispensed to qualified patients from treatment centers.

If you’re new to the cannabis community, medical marijuana can seem a little confusing. But not to worry! CannaMD is committed to fostering patient education and making treatment as easy to understand as possible! So let’s start at the beginning, with some medical marijuana basics…

What is marijuana?

Marijuana (also known as cannabis) is a variety of the Cannabis sativa plant, which is part of the Cannabaceae family. While researchers are still trying to pinpoint an exact number, recent studies suggest marijuana contains over 100 unique chemical compounds called cannabinoids.

Cannabinoids are what make marijuana “work”. (More on that in a later post…)

For now, all you need to know is that different cannabinoids do different things. For instance, tetrahydrocannabinol (THC) gives marijuana its psychoactive effect. Cannabidiol (CBD), on the other hand, exerts its influence without any type of “high.”

Is marijuana really medicine?

Marijuana as medicine dates back to 2900 B.C., with the Shennong Ben Cao Jing (an ancient Chinese text) recording prescribed uses for rheumatic pain, malaria, and other common ailments. Archaeological and historical accounts also suggest cannabis was used, in combination with wine, to anesthetize patients during surgery.

While Western medicine didn’t pick up on the treatment until the early 19th century, researchers were quick to hop on board; by the end of the century, there were over 100 publications on medical cannabis in Europe and the United States.

In 1976, the United States Controlled Substances Act classified cannabis as a Schedule I drug, abruptly halting most marijuana research and making access to critical resources for future studies difficult to achieve.

Fortunately, recent social, political, and legislative changes have turned the tide.

In 2017, the National Academy of Sciences released a report that reviewed 10,000 scientific abstracts and reached nearly 100 conclusions that found countless medical uses for marijuana and cannabis-derived products.

“Regular” versus medical marijuana

Wondering what’s the difference between “regular” marijuana and medical marijuana? (You’re not alone! We get that question a lot!)

The short answer? It depends on where you are and what you’re using it for.

Marijuana is marijuana. So the distinction really comes down to legal definitions (currently decided by each state) and how the plant is being used.

In a nutshell, “regular” or recreational marijuana is used without any medical justification.

As Harvard researchers explain:

Although products used by recreational marijuana consumers and medical marijuana patients are derived from the same plant species, they are generally utilized for different purposes (i.e., to get high/alter one’s current state of being vs. symptom alleviation). Accordingly, recreational and medical users often seek different marijuana products with various constituent compositions based on the desired effect. Recreational marijuana users often seek products high in THC, the main psychoactive constituent of the cannabis plant, and while medical patients may also choose products with high THC levels they often seek products high in other potentially therapeutic cannabinoids.

So what does Florida legislation say?

According to Senate Bill 8A, all parts of any Cannabis plant count; however, marijuana is only considered “medical” if it’s dispensed from a medical marijuana treatment center to a state-qualified patient.

What about hemp?

Everybody gets so confused about hemp!

True story: Even the United States government can’t keep it straight! (For more on that mix-up, check out our blog post: What is Hemp? And Why Does It Matter?.)

Hemp is another variety of the Cannabis sativa plant. However, while hemp shares a lot of common properties with marijuana, there’s one big difference:

Hemp can’t get you high.

According to the Ministry of Hemp:

Your lungs will fail before your brain attains any high from smoking industrial hemp.

Yep, it might not sound exciting, but hemp seeds are primarily used in food products (such as bread, milk, and cereal) and/or made into oil (including fuel, paint, and ink). Fiber from the plant’s stalk is often used in clothing and construction.

Fun fact: Hemp is more sustainable and 60 times faster to market than lumber.

Still confused? Think about marijuana and hemp as siblings. They share much of the same genetic makeup, but they’re two unique individuals.

Tell me more about cannabinoids

No problem! Here’s a little cannabinoid trivia:

  • Cannabinoids are sometimes called plant cannabinoids or phytocannabinoids
  • THC is the only plant cannabinoid (that we know of) that has clear psychoactive effects on its own
  • We’ve already reviewed THC and CBD; CBN (cannibinol) is another big player (known for making people relax)
