CBD, THC and THCA are three well‑known cannabinoids that appear on product labels and lab reports. They are related but not identical, and they are treated differently in many legal systems.
This guide compares CBD, THC and THCA at a high level. It is not medical, dosing or legal advice. Laws change often, and only local regulators and qualified professionals can tell you what is allowed where you live.
CBD in brief
CBD is generally described as non‑intoxicating and is widely used in hemp‑derived oils, gummies and topicals. Many products highlight CBD content in milligrams per serving and share third‑party lab reports.
Some regions allow CBD products under specific rules; others treat them differently. Always check labels and local guidance if you are unsure what is permitted.
THC & THCA in brief
- THC is usually associated with feeling “high”.
- THCA is a precursor that can turn into THC when heated.
- Lab reports may show both THC and THCA separately.
- Some laws calculate “total potential THC” using both values.
- Age limits and possession rules can be strict in many areas.
