Cannabidiol (CBD), a naturally occurring cannabinoid found in cannabis, has gained widespread popularity for its potential health benefits.
Thanks to the 2018 Farm Bill, hemp-derived CBD products, which contain less than 0.3% THC, are federally legal in the United States, meaning a medical card is not required for these products.
However, things can get a bit more complicated, as state-specific laws can impact the legality of CBD, especially when derived from marijuana or containing higher THC levels.
While hemp-derived CBD is generally accessible, marijuana-derived CBD often requires you to be part of a state-run medical or recreational cannabis program. Keep in mind that each state has its own rules, and the distinction between hemp and marijuana CBD can affect whether or not you need a medical card.
Why CBD Legality Isn’t Black and White
The legality of CBD is complicated. At the federal level, CBD products that are derived from hemp (containing less than 0.3% THC) are legal in most states, but the picture changes at the state level. While some states have embraced CBD use in all its forms, others impose strict regulations or ban certain types of CBD products altogether.
In some cases, a medical card might be required for certain forms of CBD, but in other states, no card is necessary. Therefore, before purchasing CBD, it’s essential to check your state’s specific regulations.

Hemp-Derived CBD vs. Marijuana-Derived CBD: The Key Distinction
Hemp vs. Marijuana
CBD can be extracted from two main sources: hemp and marijuana. While both come from the cannabis plant, they are legally distinct based on their THC content.
- Hemp refers to cannabis plants that contain less than 0.3% THC, as defined by the 2018 Farm Bill. Hemp-derived CBD is widely available and is generally legal at the federal level across the United States
- Marijuana, on the other hand, contains higher levels of THC, typically above 0.3%. Marijuana-derived CBD is often subject to stricter legal restrictions and is only available in states with medical or recreational cannabis programs.
Do You Need a Medical Card for Hemp-Derived CBD?
In most cases, no medical card is required for hemp-derived CBD. Since hemp is federally legal, CBD products derived from hemp can be sold over-the-counter in many states.
However, there are exceptions. Some states have additional restrictions on the sale of CBD products, including age limits, the form of CBD (e.g., oils, tinctures, edibles), or where it can be purchased.
If you’re considering purchasing CBD gummies or other edible CBD products, you may still need to verify if your state has any specific regulations regarding their sale.
Do You Need a Medical Card for Marijuana-Derived CBD?
Yes, you do need a medical card for marijuana-derived CBD. These products are regulated by state medical cannabis programs, and access typically requires registration with a state program.
This process often involves a physician’s certification, proving that you have a qualifying condition for medical cannabis. Additionally, some states may require you to get a medical cannabis card or other form of identification to legally purchase marijuana-derived CBD.
How State Laws Impact CBD Card Requirements
The Importance of Location
The legal landscape for CBD varies significantly from state to state. While hemp-derived CBD may be widely available across the country, marijuana-derived CBD can be subject to different regulations depending on where you live. Let’s look at a few examples of state laws to understand the nuances.
Examples from Top-Ranking States
- Oklahoma: In Oklahoma, a medical card is required only for cannabis-derived CBD. While hemp-derived CBD is legal without a medical card, marijuana-derived CBD can only be accessed through the state’s medical cannabis program. Patients must undergo a physician evaluation and meet the state’s qualifying conditions before applying for a medical card.
- Virginia: In Virginia, medical cannabis products require physician certification but the state card is optional for purchase. This means that while a doctor’s recommendation is necessary to legally purchase medical cannabis, residents do not need a state-issued medical card to buy CBD products. However, those with a card may have access to additional benefits, such as discounted prices or more product options.
- Georgia: Georgia has a Low-THC Oil Patient Registry Card for individuals using specific CBD products that contain low THC (less than 5%). This registry is required for the purchase of any products on the state’s medical cannabis program. This is an example of how states can create unique systems for cannabis access, even for specific forms of CBD.
- Texas: Texas does not require a physical medical card, but doctor certification and registry entry are mandatory for accessing certain CBD products under the state’s medical cannabis program. This means that even though a patient won’t have a card, they must still be registered in the state’s registry to legally purchase marijuana-derived CBD.
Beyond the Card: Other Important Factors
THC Content Levels
Beyond just the hemp vs. marijuana distinction, THC content plays a significant role in determining whether you need a medical card for CBD. States vary in how much THC is allowed in CBD products, which can affect both the need for a medical card and the legality of the product. For example:
- Some states, such as California, allow higher THC content in CBD products without the need for a medical card.
- Other states, like Florida, may have stricter THC limits, requiring a card for products that exceed certain THC thresholds.
It’s important to check the THC content of the CBD product you’re considering, especially when purchasing items like CBD gummies, to ensure it complies with the state laws where you reside.
Where You Buy Your CBD Matters
It’s not just about having a medical card or not – it also matters where you buy your CBD products. In states where CBD is legal, you may still face risks if you purchase from unregulated retailers.
These retailers may sell products that aren’t properly tested for quality, potency, or safety. Buying from a licensed dispensary ensures that the product has been tested and meets the state’s standards for quality and compliance.
Potential Legal Risks
One of the biggest concerns for CBD users is the legal risks associated with traveling or purchasing from unregulated sources.
For instance, transporting cannabis products across state lines is illegal under federal law, even if both states have legal cannabis programs. Additionally, products bought from unregulated sources may be mis-labeled or non-compliant with local laws, putting consumers at risk for legal issues.
How to Ensure You’re Complying with the Law
Always Check Your State’s Current Laws
Given the complexity of CBD laws, it’s essential to always check your state’s current laws before purchasing CBD. Laws can change frequently, and what’s legal in one state may not be legal in another. Each state has its own cannabis program, and the rules around CBD can vary widely.
Check with your official state resources or government websites to get the most accurate and up-to-date information on medical card requirements, CBD products, and any restrictions that may apply.
Understand Your Product
Understanding your CBD product is just as important as understanding the law. You should always check the source of the CBD (whether it’s hemp-derived or marijuana-derived) and the THC content to ensure it complies with your state’s regulations.
Look for a Certificate of Analysis (COA) or third-party testing results to verify that the product contains the amount of THC it claims and is free of harmful contaminants.
The Bottom Line
If you’re considering CBD products, especially hemp-derived CBD with less than 0.3% THC, a medical card is not required in most states. However, state laws vary, and some states may have restrictions or may require a medical card for CBD derived from cannabis or containing higher THC levels.
Always verify your state’s regulations before purchasing, and consider speaking with a healthcare professional, especially if you’re thinking of adding CBD or cannabis products to your health routine.
By staying informed and doing your due diligence, you can make confident choices about CBD and its legal standing in your area.
