CBD Inhaler

What is a MDI?

A metered-dose inhaler (MDI) is a device that delivers a measured amount of medication in a mist to the lungs. The mist is in the form of a short burst of aerosolized medicine that is usually self-administered by the patient via inhalation.

What are the benefits of using a MDI?

WBRx assures you are getting a true inhaler, not a sublingual, that delivers a single dose directly to your lungs. Non-patented and/or full-spectrum imitations deposit a spray on the back of your throat, which taste bad and may burn. In addition, WBRx’s product does not have to be burned, heated, swallowed or rubbed on the skin. It comes in a compact, tamper-proof, waterproof package. There are no waxes, tars, fillers, coloring, contaminants, toxins, sugar or other adulterants. 

What are the benefit of delivery of CBD directly to the lungs?

Immediate effect! The only delivery method as fast or effective is an I.V. You do not have to wait to see if you need an additional dose for your desired effect. The effect is felt in less than 5 minutes versus a pen that can take up to 30 minutes or an edible that can take an hour – our inhaler is 98% bioavailable.

Is WBRx's MDI approved by the FDA?

WBRx’s cans, valves, actuators and filling equipment are all on file with the FDA. We comply with all cGMP requirements followed by the manufacturers of our consumables and equipment except for the active pharmaceutical ingredient (API). Our API is pure CBD isolate containing no THC. While WBRx’s API is NOT approved by the FDA, we believe our formulation, which is limited to pure CBD isolate, is not toxic to humans.

Is WBRx’s MDI safe?
Our medical propellant and CBD isolate is considered non-toxic by the FDA. We use a small amount of medical inhalation grade ethanol and terpenes for flavor. CBD is not yet approved for use by the FDA except in limited circumstances. As with any substance, if you have any concerns consult your physician.
Is there any THC (the stuff that gets you high) in our inhaler?
No. Not any! Our CBD isolates are absolutely pure pharmaceutical grade. WBRx tests its CBD twice, just to make sure.
Is there an odor?
There is no smell. Our inhaler can be used anywhere without any smell whatsoever.
Is the device waterproof?
Our inhaler keeps working even if submerged in water (clothes washer, swimming pool, or beach).
Do I need to clean my MDI?
Generally, no.
What if my MDI gets dirty?
Do NOT disassemble. Clean with warm water and/or mild soap and rinse. Air dry.
Can I share my MDI?
Sharing an MDI can cause the spread of infectious diseases. Sharing is not recommended.
What does CBD do for your health or medical condition?
We make absolutely no claims whatsoever about what CBD may do for any consumer. All human bodies work differently for all types of medications. However, there is a vast amount of anecdotal evidence online regarding the benefits of CBD.
How much should I take?
Our MDI delivers exactly 5mg per actuation. There is no established recommended dosage of CBD isolate. Our experience leads us to believe a normal amount when used regularly is up to 20mg per day on an individual basis. Your results may vary. If you experience any adverse reaction whatsoever immediately discontinue use, contact your physician or emergency room.
Will the ethanol in the MDI affect my blood alcohol level (BAC)?
No. However, WBRx uses 200 proof inhalation approved ethanol for formulation stabilization purposes. If used immediately prior to an alcohol breathalyzer test, a false positive test for alcohol may result. We suggest all users who are subject to testing wait at least 10-15 minutes between use and a test as with any prescription inhaler.
How do I know the API is working?
We make no claims whatsoever our product will achieve any type of medical results. There is no legitimate testing that shows how much CBD an individual should use for any purpose. All humans are affected differently by chemical compounds of any nature. As such, what affects one person may not affect another.
How soon should I take a second dose?
We recommend you take a maximum of four (4) doses a day at least four (4) hours apart. Particularly if you are just using CBD for the first time as some individuals may experience mild irritation or slight discomfort for the first three or four days of use until they adjust to the MDI.
What is bioavailability?

Bioavailability is defined by Harvard University School of Pharmacy as, “the percent of dose entering the systemic circulation after administration of a given dosage form.”

For more information on bioavailability and its importance, visit the links below:

Why is bioavailability important?

A consumer wants to achieve a certain effect from taking any medication. To achieve the effect in the body a quantity of the substance needs to be available in the bloodstream. As bioavailability decreases a consumer must consume more of the substance to achieve the desired amount in the bloodstream. Lower bioavailability means more of the substance is lost and therefore more must be purchased and consumed. In short, this relates directly to the efficacy of the substance relative to its cost. Another way to look at this is a consumer has to use less of a higher bioavailable compound to achieve the same effect. Our bioavailability exceeds any other method on the CBD market.

What are the different types of bioavailability for CBD?

CBD 101

What is CBD?

CBD is short for cannabidiol, a compound found in hemp plants. It is a popular supplement because it interacts with receptors in your endocannabinoid system that keep the body balanced and running normally in homeostasis, the tendency toward a relatively stable equilibrium between interdependent elements. CBD is one of 80+ naturally occurring endocannabinoids found in all cannabis plant strains (including hemp).

What is the endocannabinoid system?

The endocannabinoid system (ECS) is a complex network of lipids comprising the endogenous ligands, their cannabinoid receptors, and the enzymes catalyzing the formation and degradation of endocannabinoids. Two primary endocannabinoid receptors have been identified: CB1 and CB2. First discovered in the late 1980’s, the endocannabinoid system regulates the body’s homeostasis, or general state of balance, impacting such functions as mood, sleep, appetite, hormone regulation, and pain and immune response.

Where does CBD come from?

There are over 113 known compounds (also called cannabinoids) found in the Cannabis Sativa plant—CBD, which is short for cannabidiol, is one of them along with others such as CBDA, CBG, CBN, CBC, phenolics, and terpenes—CBD accounts for about 40% of the extracts found in the Cannabis plant.

Is CBD the same as marijuana?

No. The active compound responsible for the “high” associated with cannabis is THC, which is very high in the marijuana species and extremely low (less than 0.3%) in the hemp species.

Medical marijuana is derived from the whole cannabis plant and relies on the heavy concentration of delta-9-tetrahydrocannabinol (THC) in the marijuana species, along with the full-spectrum cannabinoids, for its medicinal applications.

Hemp-derived CBD, (what WBRx uses) relies exclusively on the hemp species. To be considered hemp-derived CBD, the extract must contain less than 0.3% THC.

What is the difference between CBD isolate and full spectrum?

Isolate: The purest form of CBD is found in isolates. Isolates contain no trace amounts of other cannabinoids, terpenes, or THC. This is the THC-free alternative to the full spectrum products.

Full Spectrum: Full spectrum CBD uses the whole plant and offers the full range of cannabinoids and terpenes. This full range also includes trace amounts (less than 0.3%) of THC and, along with the other cannabinoids and terpenes, may well enhance the overall CBD effect on the body. This is referred to as the Entourage Effect.


Can you overdose on CBD?

CBD is not toxic and has very few side-effects. CBD and CBD oil have been known to produce incredible benefits and help many people who are searching for recovery or relief. So, can you overdose on CBD oil? According to the National Cancer Institute, “Because cannabinoid receptors, unlike opioid receptors, are not located in the brainstem areas controlling respiration, lethal overdoses from Cannabis and cannabinoids do not occur.”

Is CBD legal?

The 2018 Farm Bill was signed into law in December 2018, effectively legalizing hemp at the federal level by removing it from the federal list of controlled substances and classifying it as an agricultural commodity. As a result, CBD from hemp is legal nationwide at the federal level. The Hemp Farming Act, included in the 2018 Farm Bill, is considered the most important victory in the history of the hemp industry in the United States. Because WBRx’s CBD hemp oil contains less than 0.3% THC by weight, it is exempt from the Federal Controlled Substances Act prohibition on marijuana.

As of April 2019, there are only three states with restrictions on all cannabis and cannabis-derived products. These are Idaho, Nebraska, and South Dakota.

Can I travel with CBD in the U.S.?

Yes. The TSA allows CBD products, meeting the Federal Standards, to be taken on flights with you in a carry-on bag or in your checked luggage.


Both Carnival Cruise Lines and Disney Cruise Lines prohibit CBD oil on their ships.

If you’re traveling overseas, it’s generally not recommended to bring CBD oil. Both hemp and marijuana may be more heavily regulated at your destination and this can result in greater penalties.

Should I take CBD if my job tests for THC or Marijuana?

The federal government considers cannabis with less than 0.3% THC by dry weight to be hemp, and therefore legal under hemp guidelines. While unlikely; there is always a small risk of testing positive when subjecting oneself to employment tests while ingesting full spectrum CBD products immediately before a test or over long periods of time in relatively significant doses. Employment tests vary in the threshold they use to determine a positive test. We encourage all our customers to decide for themselves the likelihood that they will be tested and what that test’s parameters are before taking our full-spectrum products. Consult your physician for more information.

All WBRx products have been third-party tested and have a certificate of authenticity and are posted HERE.


How do I take CBD?

The most common ways to take CBD are through consumables, either soft gels or tinctures. Tinctures contain potent liquid that delivers the effects of the cannabinoid molecules without any smoking or other form of combustion.

In the growing consumer market, producers will often add carrier oils and other complementary ingredients, such as an orange oil to improve the taste of a tincture. Because a CBD tincture is concentrated, it’s designed to be taken in small doses. Therefore, most tinctures come with a built-in dropper that allows users to take small, carefully measured quantities. Tinctures can also be taken sublingually, or by applying them underneath the tongue.

Other potential ways of using CBD are balms, lotions, vaping, gummies, infused drinks, and others.

Are all CBD products the same?

No. As the market expands and more products hit the market, it’s more important than ever that you find a trusted source for high-quality CBD. With CBD being classified as a natural product and dietary supplement, rigorous testing practices are not required by regulators.

The methods used to manufacture CBD directly affect the safety and quality of products you might buy. That’s why it’s important that you purchase CBD products from manufacturers that you can trust.

There are numerous global sources of hemp and each variety has its own set of characteristics, including its CBD content. High-quality CBD oil products are derived from hemp that is naturally abundant in CBD and cultivated using strict safety standards.

WBRx’s researchers tested over 3,000 cultivars of hemp to find the one that would produce the optimal potency of CBD for our products.

Our non-GMO hemp is currently grown in Kentucky. While some hemp oil producers may spray toxic chemicals on their crops to control pests, our hemp is produced without the use of pesticides, herbicides, or chemical fertilizers. This ensures the health and viability of our hemp crops used for our CBD.

Third-Party Lab Testing: WBRx hemp oil undergoes our rigorous third-party lab testing process. Independent testing laboratories inspect our oil to make sure it has the ideal concentration of cannabinoids, including CBD. We also inspect for any presence of the following unwanted elements:

  • Mold
  • Mildew
  • Fungus
  • Yeast
  • E.coli
  • Salmonella
  • Mycotoxins
  • Heavy Metals
  • Residual Solvents

Because the CBD industry is still young, it’s important to do your homework and find products that are truly pure. Price is often a marker of purity; if you find a CBD oil claiming 100-milligram potency for under $40 at a gas station, for example, chances are that the CBD is not pure and cannot be sold throughout the country.

To find a product you can trust from a company with high standards for production, Use the following checklist:


  1. Make sure the manufacturer controls the process from seed to shelf and uses raw materials to start with.
  2. Ask if they do their own extracting.
  3. If they don’t do their own extracting, find out how it is done and what solvents are used for extracting.
  4. Request batch testing to make sure there are no traces of contaminants, toxins, heavy metals, etc.
  5. Finally, do your research. Find out what’s working for other people. Google. Ask friends and neighbors.
Can you purchase CBD on Amazon?

No. Amazon does not allow the sale of CBD. When you search for CBD products, you will find that the results will come back for Hemp Oil. See below for the difference in Hemp Oil and CBD Oil.

CBD Hemp Oil vs. Hemp Seed Oil?

You may have seen hemp-based oils and products at your supermarket or health food stores, but these products are different than CBD hemp oil products. The hemp products you find at these stores are likely made by cold pressing hemp seeds, which contain only trace amounts of CBD. Hemp seed oil can be a great source of nutrition, as it contains essential fatty acids, essential amino acids, and an array of vitamins and minerals. However, hemp seed products contain extremely low levels of CBD, which means they’re not a viable option for those looking to supplement with CBD.
