If you’re using cannabidiol (CBD) to treat a medical condition such as anxiety, inflammation, insomnia, or chronic pain, it might not be clear how much CBD oil you should take to help relieve your symptoms. CBD, one of many cannabinoids derived from hemp and its cousin marijuana, has seen a massive surge in popularity since the Hemp Farming Act of 2018 removed the legal hurdles holding it back.
As a result, you can now find everything from CBD candy to capsules and everything in between—but how much CBD can you consume safely? The right dosage for you depends on several factors:
Let’s have a look at the medical aspects of CBD dosage, brand dosage recommendations, biomedical, and other factors, as well as microdosing.
The US Food and Drug Administration (FDA) doesn’t regulate or provide dosage recommendations for CBD as it’s classified as a supplement. This leaves those without a prescribing doctor in the dark. If you’re not taking an adequate dose, you likely realize you may not achieve the intended results, but can you overdose on CBD oil? Is it addictive?
According to the US National Library of Medicine, cannabidiol oil is safe in daily dosage amounts (by mouth) up to 300mg for up to six months. Daily doses from 1,200 to 1,500 mg are safe for up to four weeks. Keep in mind that these time frames are just based on how long actual studies have been done on the subject. There is nothing thus far to suggest that using CBD beyond four to six months is harmful.
Higher doses (over 1,500mg) will likely make you very sleepy, but that’s typically the extent of CBD’s primary side effects. Some users may also experience:
In short, you can’t overdose on CBD.
Research by the National Institute of Drug Abuse found that CBD is not an addictive substance like alcohol or opiates. They concluded there was no physical evidence of withdrawal symptoms for CBD users.
However, this did not hold true for heavy marijuana users, who can become behaviorally addicted to the high produced by THC. Hemp-derived CBD, even the full-spectrum variety, does not contain enough THC to produce a euphoric effect, but behavioral addiction may be a concern if you are opting for marijuana-based CBD.
While CBD use has no serious side effects, doesn’t pose an overdose risk, and isn’t addictive, it can interact with certain medications, potentially reducing their effectiveness or duration of effectiveness.
Some individuals may also require special precautions. For instance, insufficient testing has been done to establish the safety of CBD use in pregnant and nursing mothers as well as children under the age of 2. Those with liver disease may also have to stick to lower doses to prevent complicating their condition. Given this, even if you aren’t taking other medications, it’s best to discuss taking CBD with your care provider before beginning use.
Likewise, if you are already being treated for the condition that you aim to take CBD for, your care provider should be made aware of your intent to try cannabidiol. They may also be able to suggest the best dosage to start with or suggest trusted brands.
In most US states where CBD is legally available, the upper limit of THC allowed in commercially produced CBD products is 0.3 percent, according to the 2018 Farm Bill. So in most places, you don’t have to worry about consuming a higher concentration of THC in your full-spectrum CBD products purchased from legal sources.
However, in states where cannabis is legal, it’s possible to purchase CBD products with higher concentrations of THC. Some evidence suggests the entourage effect of combining CBD with THC improves its efficacy for pain relief. As with all supplementation, it’s best to start with a low dose, increasing it gradually until achieving the intended effect. Consult with your doctor or healthcare provider for medical advice.
CBD products are available in various forms:
The dosage you should consume varies by product format, concentration, individual body weight, desired effects, and tolerance. While there is no FDA recommended dosage for CBD, the factors noted are the basis of most dosage recommendations for CBD-infused products.
Lakeview Pharmacy recommends 10mg CBD oil or a 15 mg capsule taken once or twice daily for their CBD oil products.
The Greener Good has dosage recommendations based on the desired effect. Mild: 9-22.5 mg, medium: 12-30 mg, or high: 15-45mg.
CBD Oil Review cites Mayo Clinic dosage recommendations suggesting various daily dosage amounts, some with time limits.
Most manufacturers recommend starting with a low dose and increasing gradually to achieve the intended effects. Consult with a physician for medical advice or if you have any questions about using CBD products. See our dosage charts below for more information.
As previously mentioned, several determinants apply when calculating your ideal CBD dosage. Personal makeup, the condition you’re treating, and the form in which you’re consuming CBD all influence how much you should take to achieve the intended effect.
Your genetic makeup, weight, age, and metabolism can all influence the recommended CBD dosage most effective for what you’re treating. Dosage amounts vary widely, with weight often being a primary determinant for calculating the correct dose, followed by the condition you’re managing. CBD’s interaction with your endocannabinoid system and its reciprocal effect on physiology can also influence your recommended dosage amount. Always begin by following the manufacturer’s recommendations for the CBD product you’re using.
How much CBD you take might also depend on what you are treating. Some citations attributed to the Mayo Clinic suggest specific dosage amounts for particular conditions. Some examples include:
The concentration of CBD in the product you’re taking will also influence your dose.
Your ingestion method, the area of the body targeted for relief, and how much time you have (or require) for relief from symptoms can all influence your CBD dosage amount as well.
If you have questions about CBD dosage for your specific condition, consult with your healthcare provider for medical advice. Here is a brief overview of the various ingestion methods, you read more in-depth about the best way to take CBD oil by clicking here.
Oral Ingestion: CBD oil, tinctures, edibles, and capsules pass through your digestive tract for absorption in the bloodstream. Typically, ingestion is a slower transmission method as a result, but it has the longest-lasting effect. It is best to consume CBD after eating to achieve the full effect.
Sublingual Ingestion: Tinctures and oil can also be taken under the tongue (sublingual), where absorption occurs through capillary transmission. This method takes effect a lot faster than oral ingestion, despite that part of the dose is swallowed.
Inhalation (Vaping): Inhalation using a vape device transmits CBD directly into the bloodstream via the lungs. It is the fastest CBD absorption method, but its efficacy has the shortest duration.
Topical Application: CBD-infused creams and lotions are absorbed directly through the skin to affected areas, such as muscles and nerve endings. Time to relief varies by the affected area of the body, dose amount, and CBD concentration.
Determining how much CBD to consume depends on factors noted earlier—body weight, the condition you’re trying to relieve, your metabolism, and the CBD concentration in the product you’re using. Before using CBD, consult with your doctor about dosage recommendations and any possible side effects or interactions with other drugs.
If you are unable to get a doctor’s recommendation, the best option is to start with a smaller dose and gradually increase the dosage until you achieve the desired result. Be sure to keep track of how much you are taking over time and note when you began to feel relief from the symptoms you’re treating.
For example, if taking 20 mg for chronic pain provides little or no relief, increase your dosage by 5 mg for a week and monitor your pain levels. If your pain becomes tolerable or is relieved entirely by a 25 mg dose, then maintain that dosage and adjust up or down as needed.
Ingesting CBD orally is the easiest way to absorb CBD into your bloodstream. There are several formats available for consuming CBD orally:
Some dispensaries and other retailers also carry baked goods, candies, and lozenges containing CBD. Consuming products like gummies, sweets, or soft gels can make dosing easy since each serving contains a pre-measured dose using a specific concentration.
Liquids like CBD oil and tinctures require measuring out your dose with a dropper. The concentration of CBD in your oil or tincture will also determine the dosage amount per drop. CBD tinctures and oil can be added to food, as well. Be sure to consult the product instructions for dosage recommendations.
Once you’ve calculated the correct dose for your weight and intended result, you can take the corresponding amount using whichever solid or liquid CBD product you prefer. Please see the CBD dosage guide below for notes and details for converting fluid measures to weights (in mg), as well as dosage recommendations by weight.
Typically, sublingual (under the tongue) application of CBD involves an oil or tincture. The amount you place under your tongue is similar to oral ingestion. CBD tinctures and oils usually come in 15 ml or 30 ml bottles. CBD concentration can vary from 25 to 1,500 mg per bottle (15 ml or 30 ml). A single 1 ml dose from a dropper will contain a different amount of CBD depending on the concentration of the product you selected.
Always read the instructions that accompany your CBD product for dosage information. Your weight and the intended effect are the other main factors in calculating your dose. The dosage charts below can help you determine how many drops of oil or tincture correspond to the amount you want in milligrams by CBD concentration, and how much to take for the intended effect.
Inhaling CBD by vaping, smoking concentrates, or high-CBD cannabis is the least precise way of measuring CBD intake. While a vape cartridge or refillable tank may have a specific capacity (e.g., 200 mg), there is no way to precisely measure the CBD contained in a single puff. Nor is there a way to know how many puffs are required to achieve the intended result.
Factors that influence the amount you take include weight, the area of the body or symptoms you’re targeting, and the bio-availability or amount of CBD absorbed by the body when vaping. Vaping has the highest bio-availability of all the absorption methods discussed. You can do the math and calculate how many puffs it takes to consume 50 mg (half) of a 100 mg cartridge, determining milligrams of CBD per puff, or count the number of puffs required to achieve the intended effect.
Note: reports as recently as December of lung distress due to vaping were caused by contaminated nicotine and cannabis vaping fluids. Make sure your CBD for vaping comes from a reputable source and contains no additives.
Similar to inhaling CBD, topical applications are challenging to calculate since the “dose” depends entirely on how much product you apply to your skin. Topical product CBD concentrations can range from 250 to 1,500 mg. Those with severe or chronic pain may prefer using higher concentration products.
It is equally challenging to recommend a topical CBD dosage since:
Discuss topical CBD treatment with your healthcare provider for safe usage and dosage guidelines. Also, be sure to use topical CBD products as directed. Most topical formulations are not intended for oral consumption (including massage oils).

Microdosing is a growing trend among CBD users for boosting athletic performance, enabling CBD consumers to reap the maximum benefit throughout their day, and for using full-spectrum CBD derived from cannabis to minimize the amount of THC consumed.
Microdosing is breaking up your daily CBD dose into smaller doses taken incrementally throughout the day. It allows you to enjoy the health benefits of CBD and to customize your daily dosage for your needs, lifestyle, and the condition you’re treating.
The intention is to help you reap the most wellness benefit from your CBD by maintaining a consistent level in your bloodstream throughout the day. It also allows those using cannabis-derived CBD to enjoy its effects without intoxication.
You can microdose using any number of widely available edible CBD products.
Other factors, such as time, convenience, and discretion, may influence your choice of edible format. There may be times or occasions when using an oil or tincture is not appropriate, but a gummy works just fine. You can also opt for multiple delivery methods. For example, you may use a tincture at home and a capsule at work.
If using a small amount throughout the day and staying within limits recommended for your weight and treatment level, any risks are minimal. However, consult with your health care provider if you have any questions about microdosing or using CBD.
Determining how much CBD you should take is not a straightforward question to answer. CBD is a non-addictive, non-intoxicating substance praised for its health and wellness benefits. The recent legal status of hemp has resulted in an explosion of CBD products on the market in a lot of forms—edibles, topicals, oils, tinctures, and capsules. With such a vast proliferation of cannabidiol products out there, it can be hard to pinpoint the correct dosage amount.
Each product should come with dosage recommendations, which should be your first point of reference. However, depending on the format of your CBD product, how you ingest it, your weight, and the area of the body or condition you’re treating, your dose amount may vary.
No single answer or formula can tell you how much CBD to take. However, options like microdosing allow you to start small and ramp up your dosage amounts incrementally. Also, practitioners believe microdosing provides the wellness and benefits of CBD usage more evenly through the day than a single daily dose.
As with any dietary or wellness product not regulated by the FDA, it’s best to consult with your healthcare provider to ensure there are no known side effects or other drug interactions in your case that would result in an adverse reaction from using CBD products.
Your health and wellness are your number one priorities. Use CBD with caution until you have established a dose that relieves the medical condition you’re seeking to address.
