CBD is here to stay! The growth of the CBD industry since the passage of the 2018 Farm Bill is jaw-dropping, to say the least. In a 2020 Single Care study, one-third of Americans surveyed said that they had tried CBD products. While CBD has found its way into countless products, from coffee to dog treats, many Americans don’t know that the active ingredient, cannabidiol comes from CBD hemp flower— a nearly identical flower to marijuana.
Intrigued? We thought so! In this post, we’ll talk about
- What CBD hemp flower is
- Where it comes from
- And, how hemp is different from marijuana
What Is CBD Hemp Flower?
CBD hemp flower, sometimes called hemp buds, are the flowers of female hemp plants. As a female hemp plant enters the flowering stage of its lifecycle, it diverts energy away from growing taller to producing sticky, trichome-covered flowers to catch airborne hemp pollen.
Trichomes are like nature’s velcro— they catch pollen out of the air and deter would-be predators with their pungent smell and bitter taste. Trichomes are also where CBD and other phytocannabinoids are created and stored.
Hemp flowers that catch airborne pollen stop producing large amounts of cannabinoids and end up producing seeds. Female hemp plants that are never pollinated make more trichomes and end up creating more sought-after cannabinoids. The hemp flowers that we smoke and extract CBD from come from unpollinated female hemp plants.
How Is Hemp Flower Defined?
According to an official USDA memo, hemp is defined as cannabis that contains no more than 0.3% delta-9 THC and is no longer included on the DEA’s Schedule I controlled substance list.1 The Farm Bill also says that hemp and hemp derivatives as defined by the bill are considered to be agricultural commodities.
Some states, like Idaho and Texas, have since banned the sale of smokable hemp flower in-state. But that can’t stop you from buying hemp online and entities like the United States Postal Service from delivering hemp to residential addresses.2
What Is CBD?
CBD is short for cannabidiol, a phytocannabinoid produced by hemp plants. CBD is not psychoactive and won’t make you feel high when you smoke or ingest it.
As of this writing, there aren’t many FDA-backed studies on CBD’s effects on humans, though there is an FDA-approved drug, Epidiolex, that’s derived from CBD oil that’s used to manage rare forms of epilepsy. 3

Are CBD Hemp And Marijuana The Same?
Hemp flower and marijuana are not the same. While they are both flowers of the Cannabis Sativa plant and look, smell, and smoke the same; the effects you get from smoking each couldn’t be more different.
What Does Hemp Flower Do?
A lot of the physiological science about consuming hemp flower is still in the early stages— though that’s what happens when a substance is placed on the DEA’s Schedule I list for so long— we stunt research.
(This writer is a little salty about it)
There is a growing online community of hemp flower users, smokers, bakers, and extractors that are amassing a treasure trove of personal experience with hemp flower. Many of these users report that CBD hemp flower helps them manage a range of issues and symptoms like,
- Restlessness and sleep 4
- Appetite 6
- Feelings of anxiety 5
- Pain caused by arthritis or other joint issues 7
- Sore muscles caused by overuse
- Excessive stress
- Number and severity of seizures
- And more…
While the U.S. Food and Drug Administration has so far only approved Epidiolex to manage rare forms of epilepsy, they are hesitant to allow companies to make claims about CBD hemp flower because its effects are under-researched. 3
Does CBD Hemp Flower Get You High?
This is a great question. Hemp flower is supposed to only contain trace amounts of THC. The legal definition of hemp is that it “contains no more than 0.3% of delta-9 tetrahydrocannabinol by dry weight,” meaning that one gram of dried flower should contain no more than 3mg of delta-9 THC.
To put that in perspective, a standard king-sized one-gram joint of hemp shouldn’t contain more than 3mg of delta-9 THC. Some states have also further defined hemp as containing no more than 1% of total THC by dry weight— 10mg in our example— an important distinction we’ll break down shortly.
This Kind Of Hemp Flower Can Get You High
Some lawmakers have introduced total THC rules in a handful of states and there is currently a movement to change the federal definition to reflect that. That’s because the 2018 Farm Bill definition of hemp is written so specifically, that folks in the cannabis and hemp industry have found countless workarounds in order to sell higher-THC flowers online.
Delta-8 THC flower is one such example. It is not a cannabinoid that commonly appears in nature though it does induce the same psychoactive effects as delta-9 THC. Delta-8 hemp flower producers first must wash pure CBD isolate in an acetate acid bath to make delta-8 THC distillate which they then spray over hemp flower. Because delta-8 and delta-9 THC aren’t the same, it’s in a legal gray area.
Another high-THC flower you may find online is called THCa flower. THCa is short for delta-9 tetrahydrocannabinolic acid, is the acidic precursor molecule to delta-9 THC. When you buy recreational marijuana, you’re buying THCa-rich flower and converting the THCa into active THC when you decarboxylate it with heat via smoking it. By marketing THCa flower as a “hemp flower,” cultivators have found a very semantic work around the spirit of the 2018 Farm Bill.
If the total THC rule is put into effect, both delta-8 and THCa flower would be considered marijuana and banned from cross-state sales.
Is Hemp Flower Safe?
For the purpose of this section, hemp flower will refer to CBD-rich hemp flower that contains no more than 1% of total THC.
CBD has been found to be non-toxic to humans, even in cases of extreme dosing.8 No fatalities have been attributed to CBD ingestion. The World Health Organization in a 2017 memo, said that “CBD exhibits no effects indicative of abuse or dependence potential.”10 CBD is neither toxic nor is it habit-forming, though it does have some side effects.
What Are Hemp Flower’s Side Effects?
A 2017 issue of Cannabis and Cannabinoid Research discussed the side effects of CBD use.9 The most common include,
- Feelings of nausea
- Mood changes
- Feelings of anxiety
- Dry mouth
- Reddened eyes
Are There Benefits To Smoking Hemp Flower?
Let’s preface this section by saying that smoking anything, hemp or otherwise is inherently risky. That said, smoking hemp flower does present some key benefits.
Smoking hemp flower and inhaling the vaporized CBD will actually increase its bioavailability, a term that refers to a substance’s ability to be absorbed and used by the body. 
Faster Than Other Methods
One of the most noticeable effects of smoking hemp flower is the speed at which its CBD enters your bloodstream. When you inhale vaporized CBD it comes in contact with your lung’s network of capillaries almost immediately and can reach peak concentration in your bloodstream in just three minutes.12
Are There Other Ways To Use Hemp Flower?
In addition to smoking hemp flower or prerolls, there are plenty of other ways that you can use hemp flower and unlock the CBD inside.
Vaporize Your Hemp Flower
Vaporizing hemp flower is a lot like smoking hemp flower, but without the combustion and ash. A lot of people prefer vaping to smoking for a number of reasons like smell, ease, and health.
Bake Your Hemp Flower Into CBD Edibles
You can turn your CBD hemp flower into any number of tasty homemade treats that will be sure to help you relax and melt into the couch at the end of a long day. A number of people prefer edibles to smoking hemp flower because of the duration of effects, convenience, and taste— who doesn’t love sweets?
In fact, we have plenty of blogs to help you get started making edibles at home!

Extract The CBD From Your Hemp Flower
If you don’t want to smoke hemp flower and instead want to use the CBD inside for another project, you can do so using either ethanol or some form of fat, like coconut oil. Extracts can be used in tons of products like tinctures, topicals, and even candy!
Tumble Your Hemp Flower For Kief
Kief is the term for the collection of trichomes that can break off cannabis flower— hemp or marijuana. You can use kief to enhance your smoking or baking experience because it’s generally more potent than raw hemp flower.
Is CBD Hemp Flower Legal?
This blog post is not and should not be considered legal advice. We are publishing this in the state of Vermont for purely informational purposes. If you have any questions about your state and hemp, please contact a LOCAL attorney.
According to the 2018 Farm Bill, hemp is “cannabis that contains less than 0.3% THC.”13 and is no longer included on the DEA’s Schedule I controlled substances list. Hemp is now considered by the federal government to be an agricultural commodity and certain products, like CBD hemp flower and products derived from the hemp plant, are considered federally legal.
Aside from hemp flower cultivation, the processing, sale, and transportation of CBD hemp flower products are also legal. (Provided your vendor has the right paperwork!)
Can You Buy CBD Hemp Flower Online?
You can buy and have CBD-rich hemp flower online delivered directly to your door or P.O. box by the United States Postal Service. As of right now, states can’t interfere with legal interstate commerce. But before you buy any hemp flower online, you should equip yourself as a buyer. Because the world of online hemp is unregulated and there are some bad actors out there.

Before you buy any hemp flower online, you should look for that product’s corresponding test results. Sometimes called “batch tests” or “certificate of analysis,” these documents should tell you exactly what’s in your CBD hemp flower. That includes cannabinoids, terpenes, any heavy metals, and residual pesticides.
For your health and safety, you should only buy hemp flower grown in the United States. This license isn’t just for your benefit though. It can also be helpful if any United States Postal Inspection Service member decides to pull your package because it smells like cannabis.
