Topicals vs. Gummies: The Milligrams Don't Tell the Same Story

One jar says 3,500 MG. Another package says 100 MG. It is tempting to assume the first must be thirty-five times stronger. Unfortunately for simple arithmetic, those products are not even making the same kind of claim.

A skin-applied cream and an edible gummy can both list cannabinoids in milligrams, but the number needs an ingredient, a unit, a container size and a route of administration before it tells you anything useful. The size of the typography on the front label does not provide that context.

A milligram is a mass unit, not an outcome

A milligram measures how much of a substance is present. It does not explain what that substance will do, how much reaches a particular tissue, or whether a product performs as marketed. A label that says 3,500 mg might refer to the total CBD content of a cream container. A gummy marked 100 mg might describe a single piece containing several cannabinoids combined.

Even if both numbers describe cannabinoids, we still need to ask: Which cannabinoids? Per piece or per jar? How concentrated is the ingredient? What else is in the formulation? Comparing the two numbers directly skips every question that matters.

The topical label describes a different format

A topical is applied to skin. A product might contain CBD in a cream, balm, lotion or gel together with ingredients that determine its texture and how it spreads. The ingredient list may include botanicals, fragrances or cooling agents that have their own distinct roles. The cannabinoid amount on the container is not a standard per-application dose unless the label explicitly defines one.

Take the Tall Trees Rooted Relief topical. Its current listing identifies a 3,500 mg cannabinoid-focused cream formulation with CBD, CBC and CBG plus non-cannabinoid ingredients. That figure should be read alongside the current product label, net quantity, cannabinoid breakdown and application instructions. It should not be compared directly with a gummy's per-piece amount.

The phrase topical also needs precision. Ordinary skin-applied products are not the same thing as delivery systems specifically designed to move compounds through the skin and into circulation. Research has found absorption from some cannabinoid skin formulations, with important variability among products. An absolute statement that no topical cannabinoid can ever enter the bloodstream would go beyond the evidence.

The edible label describes a swallowed product

An edible is ingested, so digestion, absorption and metabolism become part of the story. A gummy can be labeled with milligrams per piece, and a package may contain several pieces. If the formula includes multiple cannabinoids, the front number might be a combined total rather than an amount of Delta-9 THC alone.

Our Canopy Cruisers 100MG Hemp Gummies use a multi-cannabinoid formulation. The listing's 100 mg per piece does not make it equivalent to 100 mg of CBD in a cream, nor does it mean 100 mg of Delta-9 THC by itself. A product's ingredient breakdown is more informative than one headline number.

For a closer look at piece-versus-package math, see How Many Milligrams of THC?. That article explains the dosage labels; this one explains why the comparison falls apart across product formats.

Concentration is another missing variable

Imagine two creams with the same total milligrams but different jar sizes. The smaller one may have a greater concentration per gram of finished product. The larger one may spread the same total amount through much more cream. Without knowing the net contents, a total milligram claim alone does not resolve the difference.

There is a parallel issue with gummies. Two edible products with the same combined cannabinoid total could contain very different proportions of CBD, Delta-9 THC or other constituents. The chemistry on the label matters more than an apparent tie in arithmetic.

What do human studies actually tell us?

Published human research has evaluated several commercial hemp-derived topical CBD products. A 2024 study of 46 adults reported detectable transdermal CBD absorption with some of the studied formulations, not all of them. The investigators also emphasized the limited evidence and differences across product types. A separate exploratory study of a specially designed transdermal cannabinoid system showed systemic absorption, which is exactly why ordinary topical creams and engineered transdermal delivery systems should not be casually treated as identical.

Neither study lets someone predict the absorption or clinical performance of every product sold in a jar. Those would require product-specific evidence. The FDA also warns about unproven CBD treatment claims, potential drug interactions and gaps in safety data. Label education is useful; making a therapeutic promise from a milligram number is not.

A better way to compare the labels

Start with four questions. What cannabinoid is named? CBD, Delta-9 THC and a mixed blend are not synonyms. What is the unit? Per piece, per serving, per container or per gram of cream? What else is present? Look for supporting cannabinoids and other ingredients. What does the product's label actually direct? The route, intended application and warnings matter.

If one of those questions cannot be answered from the packaging and supporting documentation, the answer is not to guess. The answer is to look for better product information.

Frequently asked questions

Is 3,500 mg of topical CBD stronger than 100 mg in a gummy?

There is no valid direct comparison from those numbers alone. They may describe different cannabinoids, different units and different routes of use.

Are topicals absorbed into the bloodstream?

Some formulations have shown systemic absorption in human studies. The degree depends on the formulation and other conditions. It is not accurate to promise that every topical stays entirely on the skin or that every topical behaves like a transdermal patch.

Can I compare two topical containers by total milligrams?

Only partly. You should also look at container size, concentration, cannabinoid identities, ingredients and directions.
