Understanding CBD Hemp Flower Dosage

Like any herb, CBD users are often curious about how much CBD they can take in a sitting. Another way to express the statement is by exploring the optimal dosage per sitting. It is an important question and one that needs to be answered often. After all, even with CBD products, too much is too much.

But understanding CBD hemp flower dosage is more than testing your limits. The right dosage of the right strain can produce the desired effect and give you a positive experience every time. Below, we look at the mathematics of CBD and understanding CBD hep flower dosage.

How to Calculate CBD Dosage

The easiest way to figure out your dosage is by using this formula:

Flower weight x percentage of CBD = CBD dosage.

Remember that every CBD strain (flower) is different and contains different levels of CBD. So make sure you know your product before calculating the dosage. Here’s an example of calculating CBD dosage when smoking the product.

Flower Strain CBD Percentage: 20 percent

+ Smoking Amount: 1 gram (1,000mg)

= 200 milligrams of CBD

Remember: when you smoke CBD hemp flower, your body does not absorb 100% of the CBD. Some of the CBD goes up with the smoke. So, you’ll need to adjust your dosage accordingly.

How Much CBD Can I Take?

How much CBD you should take depends on four main factors, including

1. Body Weight

Your body comprises muscle, fat, organs, and systems. The larger your body structure, the more of these body parts you have. That means it takes more to absorb the CBD. As a result, you’ll need a larger dosage to feel the effects of the drug.

2. Medical Condition You Are Treating

You can use CBD oil to lessen the symptoms of a variety of mental and physical medical conditions. How much CBD you use depends on the condition. For instance, you may not need the same dose for anxiety as for chronic pain.

3. Body Chemistry

Earlier, we discussed body weight. While weight can factor into your body chemistry, other things to consider, such as digestion, metabolism, nervous system, and overall health. Your body chemistry can determine how much CBD you need for the desired effect.

4. CBD Concentration

Some CBD hemp flower strains have a high concentration of CBD. Others have a small concentration. When you combine concentration with your body weight and body chemistry, it has a unique effect on your body.

You may want to consult your doctor or a CBD specialist to determine the right dosage for your body. Or you can start with a small CBD dosage, such as 20 to 40 mg per day. You can gradually increase the dosage to 40 to 50 mg per day. Wherever you start, make sure you know and respect your body’s threshold.

CBD Bioavailability

What is CBD bioavailability?

CBD's bioavailability tracks how much of the compound has successfully been absorbed into the body, depending on how it has been taken. This data is useful to manufacturers, who can use it as a jumping-off point for adapting their products to increase CBD bioavailability in the future.

Below is the bioavailability of 4 different delivery methods:

  • CBD topicals: <1%
  • CBD capsules and edibles: 5-15%
  • CBD Oil drops: 20-30%
  • CBD vapes: ~56%

For example, if you consume 15 mg of CBD in oral drops, you’re going to end up with 4–6 times the amount of CBD in your body than you would with a capsule containing the same concentration.

The bioavailability of CBD topicals is measured at 0% because none of the CBD applied to the skin makes it to the bloodstream. Instead, CBD reaches the cannabinoid receptors in the skin and muscles.
