What You Need to Know Before You Purchase CBD Oil: Ultimate CBDfx 2019 Guide

So, you’ve decided that you want to purchase CBD for the first time — or maybe you’re ready to move on from a CBD brand that’s let you down. Either way, now’s the time to firm up your facts on CBD, its effects, and how to use it. Here at CBDfx, we figured we’d make things nice and easy with this comprehensive 2019 CBD purchasing guide. Find out the 10 questions you should be asking before you buy CBD oil, and brush up on the basic facts of cannabidiol to make sure you get the most out of your purchase.


10 Things You Need to Know Before You Buy CBD Oil

First, let’s cover 10 of the most important things you should know to maximize the value you derive from your CBD purchase. We’ve hand-picked the following questions to give you a leg up on your CBD quest, and let us know if you have any burning questions we didn’t answer:

1. What Effect Does CBD Have?

First thing’s first: let’s be very clear about the fact that the FDA has not yet approved the use of CBD to self-treat any specific condition or symptom, and CBDfx doesn’t make any claims regarding the use of our products to that end. That’s why learning more about the documented and anecdotal effects of CBD is the first thing you should do if you’ve decided to use CBD cream for acne, CBD gummies for depression, or any type of CBD product for a condition that’s bothering you. Before we answer your questions regarding CBD drops effects, CBD tincture benefits, or any other pressing CBD topics that might be on your mind, it’s crucial to provide a brief overview of the current state of the CBD industry.

The most recent major landmark in the history of CBD was the passage of the Agriculture Improvement Act of 2018 (2018 Farm Bill) last December. Congress puts together a Farm Bill every year, but what made this 2018 piece of legislature different was its inclusion of new hemp and CBD provisions.

Up until the most recent Farm Bill, the DEA had classified CBD as a constituent of “marijuana,” which remains a Schedule I drug. This technicality stymied CBD production in the country, and it was out-of-sync with other laws and regulations surrounding cannabidiol, not to mention the established science surrounding the cannabis plant. Since 2014, for instance, it’s been legal to cultivate CBD-rich hemp under special research programs, but CBD producers and investors remained majorly apprehensive about the future of the industry until the passage of the 2018 Farm Bill.

This piece of legislation removes CBD from the DEA’s definition of marijuana, which means that CBD is now legal on the federal level. But what does “legal” mean? CBD is no longer considered to be analogous with street or recreational marijuana (due to its non-intoxicating properties), but does that mean its okay to sell CBD any way you please?

According to the FDA, the answer is still “no.” Even before the passage of the act of Congress that reclassified CBD from being an illegal drug, the FDA had already approved CBD as a prescription drug treatment for certain forms of epilepsy. In all other contexts, however, this federal regulatory agency considers CBD to be a new, unregulated substance — which means that its effects and potential benefits have not yet been definitively established.

“But wait,” you say, “haven’t hundreds of studies been done into the potential benefits of CBD?” You’re right. At the same time, however, the FDA has not yet ruled that these studies provide sufficient clinical data to merit CBD’s categorization as a drug (for conditions other than epilepsy) or supplement. Despite the fact that almost half of Americans think CBD should be an over-the-counter drug, it isn’t yet clear whether the FDA will rule that CBD is a supplement or classify it as a drug, which means that, as a CBD company, we’re restricted from making any direct or indirect claims about the potential benefits that CBD might provide.

On the other hand, we can tell you all about what CBD doesn’t do. For instance, CBD is non-intoxicating, which means that it does not cause the impairment-causing “high” effect of its infamous cousin, THC. Additionally, CBD is non-toxic and does not appear to have any serious side effects, which makes this cannabinoid very different from pain-fighting opioid drugs and anti-anxiety drugs like Xanax.

Even THC-containing marijuana, which is commonly advertised as being safer than opioids, has its own share of side effects that make you think twice about whether weed is as “worry-free” as some people like to think. In addition to commonly causing temporary side effects like paranoia, the evidence is mounting that THC might even contribute to the development of psychosis. Rest assured that CBD does not have any of these effects, despite its cannabis plant-based origin.

At the most, some CBD users experience mild sleepiness, gastrointestinal distress, or dry mouth. These mild side effects haven’t stopped millions of people around the world from trying CBD, and thousands of people just like you use CBD every day.

The FDA has indicated that it intends to speed up the regulatory process surrounding CBD, so we might see meaningful change in this cannabinoid’s status in the near future. While you’re freer to use CBD than you ever have been before, we’re paradoxically now more restricted from telling you about the potential benefits of CBD due to the scrutiny that the rapidly-growing cannabidiol industry has brought upon itself with its success. Of course, at the end of the day, we’re OK with this — since there should always be a solid scientific basis for any claims that are made, and until the FDA makes its determination, you should be wary of any CBD companies who try to “sell you the moon” regarding the benefits of CBD oil.

2. Does CBD Oil Calm the Nervous System?

Since the discovery of CBD, researchers have been keenly interested in how the cannabidiol molecule interacts with the nervous system. One of the first major CBD discoveries, for instance, was that this cannabinoid does not appear to have any major affinity for the CB1 and CB2 receptors, which are the primary components of the endocannabinoid system and the neurological mechanisms that make you feel high when you ingest THC.

While this discovery clued researchers into why CBD doesn’t get you high, it opened up a whole host of new questions regarding exactly how CBD exerts its observed effects. As the result of painstaking research, scientists were finally able to discover a few mechanisms by which the cannabidiol molecule appears to affect the nervous system, and research into the mechanisms of action of CBD is ongoing.

The main tools that researchers used to determine the so-far-discovered mechanisms of action of CBD were special chemicals that block the activity of certain neuroreceptors in the brain. WAY100635, for instance, is a chemical that blocks the activity of the 5-HT1A neuroreceptors, which are the brain’s most abundant serotonin receptors. If a substance stops exerting an observed 5-HT1A-related psychological or physiological effect after WAY100635 is administered, it’s highly likely that the observed effect is caused by the activity of that substance at the 5-HT1A receptors.

The nervous system is extraordinarily complex, and decades of research are necessary to fully understand the effects that a particular substance exerts on your brain and peripheral nervous system. Published research suggests, however, that any substance that acts as an agonist at the 5-HT1A receptors possibly reduces the symptoms of psychiatric conditions like anxiety and depression while simultaneously exerting beneficial cardiovascular and digestive effects. 

Similarly, agonists at the TRPV1 receptors have been conclusively shown to reduce pain. We’ll understandably need to wait for the FDA’s go-ahead before we make any definitive statements on any potential neurological or physiological effects of CBD, but we strongly urge you to take a look at the studies that have already been conducted into CBD and the nervous system to get a better idea of the information we’re working with.

3. Can CBD Help Acne?

For most people, acne is a common annoyance that ranges from mildly discomforting to occasionally painful. Others, however, experience acne so severe that it’s disfiguring, and currently available acne treatments make sufferers wonder if the cure is worse than the disease.

While scientists initially believed that the trigger for acne was the presence of a certain species of bacteria, there’s growing backing in the scientific community of the idea that acne is an inherently inflammatory condition. If true, we’ve been barking up the wrong tree with acne treatments for the last 70 years. While knocking out all traces of C. acnes in your system certainly eliminates your symptoms, it’s starting to seem that patients with severe acne might have been able to skip all the possible liver scarring that powerful bacteria-targeting acne treatments cause by simply fighting inflammation with safe, natural substances instead.

The FDA has made it clear that it’s too soon to say whether a CBD salve for acne or another type of CBD product might help with your condition, but what we can say is that thousands of people across the world have chosen to try CBD alongside (or instead of) their existing over-the-counter products. That just goes to show how broken our system of dealing with acne is; if conventional treatments worked as they were intended and without side effects, then trying CBD for acne wouldn’t have become as popular as it is.

Regardless, you should consult with your doctor about your choice to use CBD for acne. While many doctors didn’t even know what CBD was a few years ago, this cannabinoid is now a household name — and an increasing number of GPs and dermatologists are becoming open to the idea of their patients using this substance. It’s always good to consult with your doctor before you try something new, and by sharing your experience with using CBD for acne, you might be able to help someone in a similar situation by contributing to the body anecdotal evidence on CBD available within the medical community. Keep in mind that CBD has been shown to interact with some prescription medications, so it really is important that you chat with your physician before giving CBD a try… especially if you already take certain meds.

4. Where Can I Find a Reliable CBD Oil Benefits List?

Given the current regulatory climate surrounding CBD, it can be hard to find definitive information on hemp oil tincture benefits — or any of the other benefits that CBD may (or may not) have. There are, however, a few simple approaches you can take if you want to learn more about how CBD might operate in your particular circumstances:

CBD Advocacy Sites

Since we’re engaged in the act of selling CBD-infused products here at CBDfx, we’re understandably restricted from making claims about our products. Non-profit CBD advocacy sites, however, aren’t subject to these types of restrictions. Since they don’t sell CBD products, they are freer to take a close look at the current studies and evidence surrounding CBD’s potential efficacy for certain conditions. We suggest you check out some CBD advocate sites if you’re looking for detailed information on cannabidiol studies and new developments on the potential applications of CBD for various conditions.

CBD Product Reviews

In the world of medical research, the reviews that CBD users provide are considered “anecdotal evidence.” This type of evidence doesn’t quite rise to the caliber of clinical research in terms of shaping regulation and public opinion, but anecdotal evidence is a key type of information that researchers and regulatory agencies gather to determine the potential benefits of a substance. Even the FDA made public comments a crucial part of their evidence gathering process when making some of their initial determinations about cannabidiol.

That said, take each CBD capsules review, CBD vape shot review, or other CBD product review you check out with a grain of salt. Just as you wouldn’t necessarily trust the opinion of a random person who walks up to you on the street, it’s wise to carefully examine each CBD user’s claims without passing judgment either way. After you’ve sorted through a dozen or a hundred reviews for a certain CBD product or that regard a certain CBD application, however, you’ll be able to get a better sense of the general experience, and find the information you’re looking for.

CBD Studies

As you learn more about CBD, you’ll find that the National Center for Biotechnology Information (NCBI) is your best friend. This federal institution compiles and publishes tons of studies into CBD that would otherwise only be accessible with paid journal subscriptions. While you can’t find all the CBD studies that have ever been conducted by poring over the NCBI database, this agency provides enough information to get a detailed grasp of how scientists think that CBD does or doesn’t work in terms of the effects you’re hoping for.

There are tons of other places where you can find CBD studies on the internet, and here’s a pro tip: To find the information that will help you the best in your particular situation, type “CBD for (X) studies” into your favorite search engine. Simply substitute “X” for whichever condition you want to know more about. Remember that you should primarily be looking for peer-reviewed research published in legitimate scientific journals — not just blogs and product reviews.

5. Is There A Best CBD Oil for ADHD?


By now, you’ve learned that CBDfx will not be making any claims regarding the use of CBD to treat any specific product or condition, including ADHD. That said, there are lots of different ways that you can use CBD. For instance, you can take CBD in capsules, swallow it in tinctures, or even vaporize it with a disposable CBD vape pen. Whichever way you decide to take CBD, however, you’ll need to experiment to find the solution that works best for you.

Any substance that you inhale into your lungs will provide potent and practically instant effects that generally last about half an hour. Called pulmonary administration, this ingestion method is popular when you want to experience the benefits of a substance immediately and you aren’t looking for long-term effects.

Ingesting substances orally, however, provides long-term effects that persist the entire time that the substance moved through your digestive tract. These effects aren’t as potent as those offered by pulmonary administration in part due to the fact that the liver filters out a large portion of the active ingredients you ingest.

At the same time, oral administration might be the right choice if you want the effects of the substance you’re ingesting to last all day. Sublingual and topical administration also have their own beneficial qualities no matter which substance you’re using, so make sure to try each administration method before you decide which is best for you. You may even want to try multiple administration methods at the same time!

6. The Effects of CBD: Does This Cannabinoid Have Side Effects?

In almost every clinical study that’s been done on CBD to date, scientists have been astonished to note that CBD has practically no side effects. Rare cases of hemp allergy do sometimes occur, but for the most part, people who use CBD only experience mild side effects or no side effects at all.

It’s important to point out, however, that CBD might contraindicate some of the prescription drugs you’re taking. If you’re currently using a drug that lowers your blood pressure, for instance, CBD might lower your blood pressure even further to potentially dangerous levels. That’s not the only situation in which CBD’s interaction with a drug might cause serious detrimental effects, which is why it’s so important to talk with a doctor who knows your medical history and which drugs you’re taking before you use CBD for the first time — particularly if you’re already on medication.

7. What Can I Learn from CBDfx Reviews?

You can learn just how much CBD users love our brand, for one! We have tons and tons of five-star product reviews for the items we offer at, and reading these reviews can give you insight into how our products work in a multitude of different ways.

Many of our reviews contain compelling testimonials from people who have tried our products in the hopes of a positive effect on various symptoms they experience. Other reviews, however, focus more on the attributes of the various products we sell, which provides you with confirmation of the details we list in our product description. All across the board, reading CBDfx reviews can give you a detailed grasp of which CBDfx products are right for you.

8. Does CBDfx Have THC?

Some of the products we offer at contain full-spectrum CBD oil, which does contain trace amounts of THC at concentrations of less than 0.3%. That’s far too low to make you feel “high” or even test positive on a drug test in the vast majority of cases. For every full-spectrum CBD product we offer, however, we provide another option with broad-spectrum or isolate CBD, which contain no THC whatsoever. The type of CBD we use in each product is included in the ingredients list or product description, but reach out to us if you have any questions about which type of CBD is present in the product you’re considering. If 0.3% THC is still too much THC for your specific needs, stick to isolate CBD or broad-spectrum CBD products.

9. Where to Buy CBDfx?

Right here at is the best place in the world to buy our products. We routinely offer sales and other discounts, and new CBDfx products are available here before you can find them anywhere else. Plus, the CBDfx blog is considered to be one of the most definitive sources of CBD information on the internet.

10. Can I Save Money with CBD Bundles?

Of course! We offer a wide variety of CBD discount bundles here at, and you can use these bundles to save while getting more out of your shopping experience. If you want to try both CBD capsules and disposable CBD vape pens at the same time, for instance, there’s a bundle for that, and if you can’t decide between our four epic CBD balms, there’s a bundle for that too. If you have any favorite products that you’d like to see bundled, we always love to hear suggestions from our customers.

Buying CBD Online: Basic Overview

Now that we’ve covered the top 10 CBD questions you should ask, there are a few more points we should cover to ensure you have everything you need at your disposal to make an informed purchase. Whether you’re entirely new to CBD or you’ve used this cannabinoid before, make sure you brush up on these basic facts and helpful tips before you proceed:

Types of CBD

One of the first things you’ll learn as you research CBD is that not all types of CBD are the same. For starters, it’s rare for any two brands to extract their CBD from the same hemp crop, and there are tons of different ways to raise, nurture, and harvest CBD-rich hemp. That’s why it’s so important to only work with brands that offer organic, non-GMO CBD.

From there, it’s also important to familiarize yourself with the different types of CBD extract on the market. When CBD is initially extracted from CBD-rich hemp, it is in a form called “full-spectrum CBD oil.” This type of extract gets this name because it’s in a viscous, oily form and because it contains the “full spectrum” of natural cannabinoids and terpenes present in hemp. While full-spectrum hemp oil contains a small amount of THC, hemp plants used for CBD production are required to contain less than 0.3% THC on a dry weight basis, which is generally considered to be too small of concentration to get you high or show up on a drug test.

With new extraction technologies, it’s now possible to remove the trace amounts of THC from full-spectrum hemp oil, and the resulting substance is called “broad-spectrum hemp oil.” This name indicates that this type of extract contains more than just the CBD molecule — but that it doesn’t offer the full spectrum of cannabinoids because THC has been removed.

Broad-spectrum cannabidiol oil is the newest type of CBD on the market, and before this product was developed, consumers who wanted to avoid THC when they used CBD resorted to isolate cannabidiol. However, this type of CBD contains nothing but the cannabidiol molecule, which some who want the full nutritive value of the hemp plant might consider “throwing the baby out with the bathwater.” Isolate CBD certainly has its purposes, however, and like broad-spectrum CBD, this type of cannabidiol extract doesn’t contain any THC whatsoever.

Finding a Trustworthy Brand

In the last year or so, CBD brands have begun spreading across the internet like wildfire. Every aspect of the CBD market has thrived due to the 2018 Farm Bill, but unfortunately, the amount of money that’s now pouring into the CBD sector has also incentivized everyone and their mother to start their own CBD brands.

Amid this glut of brand diversity, established players in the industry continue to get the most attention. While it’s easier to start a CBD brand now that this cannabinoid is so legal and so popular, things didn’t used to be this way. CBD companies that were started in 2015, 2016, or 2017, for instance, had to fight an uphill battle just to get their products noticed, and they were concerned every day about the industry’s lasting potential. Older brands have proved their mettle many times over, which means that the age of a CBD brand is a big determiner of its trustworthiness.

Even some brands that have been around forever, however, aren’t any good, which means that you’ll have to look beyond a company’s age if you want to get the full picture. One great place to start is by calculating the price-per-milligram (PPMG) for a product you’re considering and comparing it to another option on the market. It’s easy: Simply take the price of the CBD product and divide it by the number of milligrams of CBD present in the product.

Some variation in price per milligram is to be expected based on product quality and a variety of other factors. If you find that a CBD company is charging nearly twice the amount for what’s essentially the same product as another brand is offering, then it doesn’t matter how established that company may be. Price is price, so pick the established CBD brand that offers the best balance of low PPMG and high product quality.

How to Read CBD Reviews

First, it’s important to point out that there are a few different types of CBD reviews out there. CBD product reviews, which are usually left by average consumers without any specialist CBD knowledge, are plentiful but short. You can’t get a comprehensive grasp of the quality of a CBD product or how CBD might work for you without sorting through dozens of CBD product reviews left by different consumers.

CBD testimonials, on the other hand, focus more on the overall experience a consumer has with CBD or with a brand in general. Instead of providing a quick take on the benefits or detractors of a product, a CBD testimonial delivers a narrative-based snapshot into the life of someone who has used cannabidiol for a condition like yours. Keep in mind, however, that testimonials are usually provided by people with no specialized knowledge of CBD.

CBD blog reviews, on the other hand, are usually provided by people with expertise in the CBD industry or the natural health world in general. These long-form reviews are written by consumers or CBD advocates who want to get their entire points across as they extoll the virtues (or bemoan the bad points) of a CBD product they’ve tried. While cannabidiol blog reviews may still only constitute a single person’s perspective, they contain a lot more information than testimonials or short product reviews you can find on an e-commerce website can provide.

What You Should Know Before Buying CBD: The Bottom Line

The CBD market is evolving at a faster pace than anyone could have imagined. Many leaders in the CBD industry seriously wondered whether this highly promising market would even survive at all, but ever since the passage of the 2018 Farm Bill, the CBD market has been soaring to ever-greater heights.

At this point, analysts are expecting the CBD industry to exceed $20 billion per year by 2024, and this rapid expansion has been an incredible windfall to American farmers that have been negatively impacted by the current administration’s tariffs on China. CBD is a boon to the American economy, and tons of major brands are now jumping on the CBD bandwagon. It simply remains to be seen how the FDA will end up coming down on an industry that has rapidly grown out of its existing regulatory framework.
