Understanding THC Percentages on Cannabis Labels — Grams Brooklyn guide

A THC percentage is a concentration measurement. It is not a rating of quality, a recommended serving or a guarantee of how someone will feel.

Percentage and milligrams are different units

One percent by weight is equivalent to 10 milligrams per gram. This arithmetic describes composition, not the amount absorbed by a person.

Total THC is a calculated value

New York defines total THC using THC plus THCA multiplied by 0.877. A total THC figure is therefore different from the report’s THC result alone. Read the report’s definitions and measurement basis.

The label cannot predict an individual response

Amount consumed, product form, tolerance and other individual factors affect response. Terpene measurements do not turn potency into a reliable prediction of relaxation, focus or other effects.

Compare like measurements

Check whether figures are per serving, per package or a percentage, and compare the same product format. Use the COA matching the batch rather than a generic strain description.
