Lisa Hamilton, a jeweler and doula in Brooklyn, NY, knows about the side effects. She recently tried CBD for the shoulder pain that plagued her five years after an accident. Her doctor certified that she was in chronic pain, which under New York State law allowed her to buy from a state dispensary. One Friday, she swallowed two 10-mg capsules, the amount recommended at the dispensary, then took another two on Saturday. “By Sunday, it felt like I’d gotten hit by a truck. Every muscle and joint ached,” Hamilton says. She cut back to one pill a day the following week, but still felt hungover. She stopped after that.
Weight plays a role in the effects of CBD oil, and bottle size should be selected based on how much you weigh. Let’s say you weigh less than 130 pounds and desire light CBD oil effects; this means that 11 mg or less will probably suffice per dose, giving roughly 40 doses from a 450-mg concentration. If you weigh more than 230 pounds and desire strong effects, then this same concentration will supply roughly 10 doses.

Hemp Bombs offers high-strength CBD in the following concentrations: 1000mg, 2000mg, and an *insane* 4000mg. This is in addition to their regular strength products (75mg, 250mg, 300mg). These high-strength CBD oils are available as either flavored e-liquid or a flavorless tank additive if you already have an e-juice flavor that you love. If you’re the type of person who needs a high strength product to feel the effects, the 4000mg bottle of e-liquid will be perfect for you. It costs a pretty penny but it lasts an incredibly long time.


Research on CBD and anxiety has generally looked at cannabis as a whole product, not as CBD as a standalone compound. Some studies suggest that it can help with anxiety: like this 2011 study that suggests CBDcan reduce social anxiety or this 2015 review that says CBD could be promising for many forms of anxiety. It’s also important to consider whether the CBD comes from the cannabis plant and therefore may include THC, a cannabinoid that for some, induces anxiety.

CBDPure has both strengths and weaknesses. We’ve seen worse, and we’ve seen better supplements. To minimize investment risks, we advise that you test the customer service first, by sending them an email, and only place the order after you’ve made sure they are responsive. They have an online chat option. However, considering that the website and the terms and conditions ask that you send emails, it is safer to stick to their recommendations.
Under federal law, cannabis (from which both CBD and marijuana are derived) is illegal everywhere, although the laws against it aren’t generally enforced in states that have legalized marijuana. Some manufacturers claim that CBD culled from legally imported industrial hemp, which has little to no THC, is fine to ship across the U.S., but many experts disagree, noting that because hemp comes from the same species as marijuana, cannabis sativa, all CBD falls under the DEA’s Schedule 1 designation. “This creative interpretation of the law runs afoul of reality,” says the Brookings Institution, a Washington, DC, think tank.
We’ve ranked every one of the high-strength CBD vape oils on this list according to a variety of attributes. We’ve graded them according to potency, quality, strength, flavor, shipping speed, customer service, and pricing; among other factors. Every one of the products on this list has been hand-selected by our editorial team. No matter which product you buy from this list, you can rest easy knowing that you’re buying one of the best high-concentration CBD oils on the planet today.
Tinctures – Typically tinctures are small glass or plastic “dropper” bottles that have cannabidiol oil mixed with a preserving solution such as alcohol. Tinctures were very a very common way to ingest botanical oils prior to the industrial revolution and are experiencing a resurgence in popularity as more people are looking for natural remedies. Tinctures with droppers allow you to put a few drops in your tea, under your tongue, or to bake the oil directly into your food.
Vaporizers – Many state-licensed cannabis dispensaries offer high CBD strains of cannabis flower. This allows for reduced risk of paranoia while allowing for a high medicinal dose of CBD. Vaporizers are used to heat up the flower and remove the properties or compounds of the plant that you are looking for without combustion or smoking. Vaporizers use convection much like a convection oven.
A major theme when reviewing the research on the best CBD for pain is the need for more large-scale clinical trials on CBD in isolation from other cannabinoids like THC. That’s not to say that THC is bad. It’s developed a stigma because it makes you high, which makes people think of hippies and the sixties and maybe your perennially stoned neighbor who clearly doesn’t have his stuff together. But THC also comes with a pretty respectable list of benefits. These range from antiemetic (anti-nausea) and anti-inflammatory effects to appetite stimulation.

But scientists have found that CBD doesn’t bind well with endocannabinoid receptors. Instead, CBD influences the system indirectly. This creates many benefits, which is why you’ll hear of CBD as a treatment for so many different medical conditions. And, unlike THC, it won’t make you high. When it comes to pain, we know that CBD has multiple functions. First, it influences neurotransmitters and receptors. One receptor known to be involved with pain and inflammation is called TRPV1 — also known as a vanilloid receptor. CBD binds to the TRPV1 receptor, influencing the way you perceive pain. CBD can also affect the production of neurotransmitters like serotonin and glutamate, which are related to pain sensation.
Our hemp oil tinctures offer the most accessible means to getting started with CBD hemp oil supplements. Registering our lowest price point among our products, our 1 oz tinctures contain the lowest concentration of CBD in our products. With around 1 mg of CBD per serving, our 1 oz tinctures are good for those looking to integrate the smallest amount of CBD into their daily routine. The tinctures in the 2 oz bottle add 2.5 times the potency, for a total of 500 mg per 2 oz bottle.
The science behind CBD is in the relatively early stages. As a cannabinoid, we know that CBD interacts with receptors in your endocannabinoid system. The endocannabinoid system is integrated throughout your body — and this widespread, whole-body interaction creates a broad range of effects. Hence, the long list of possible benefits.   We may still be in the early stages of discovery, but there’s plenty of scientific studies and anecdotal evidence that CBD provides relief for an array of ailments. Here’s a non-exhaustive list of some potential benefits of CBD oil:

Customer Service: We’ve always received fast, informative responses to our queries about products and practices, but there are definitely customers out there who have not. A quick perusal of reviews shows customers who had issues with unaddressed orders. It’s hard to know exactly what the problem is in these situations, but the company’s strict return policy (seven days for unopened products only) probably doesn’t help. It should be noted that the company has a solid base of very satisfied customers as well.
Featuring the same benefits as our pure RSHO™ hemp oil in a reduced potency, another of our midrange products, RSHO™ liquid, contains 31 mg of CBD per serving. Available in Green, Blue, and Gold Label oils, RSHO™ liquid combines our flagship RSHO™ with medium chain triglyceride (MCT) oil derived from wholesome coconut oil and sustainably sourced palm oil. Unlike RSHO™ pure hemp oils, RSHO™ liquid doesn’t need to be refrigerated, making it convenient to store wherever you need it most.
CBD Vape Oil is very popular and can be used with a suitable vaporizer. Since this oil is generally viscous, it needs a device that can work with it. Therefore, it cannot be used with all vaporizers. Make sure you have a suitable vaporizer before using a CBD vape oil. CBD Vape oils have different concentrations and flavors. Adding terpenes also contributes to the effect.
