About THC Detection Time: who writes the reference

THC Detection Time is a reference on one question: how long THC shows up on a drug test. Each figure comes from a published source (federal testing rules or peer-reviewed studies), carries a citation number, and lists the date it was last checked.

How a figure gets onto the site

1. An Editor reads the source itself, not a summary of it.
2. The figure is entered as a range, with the kind of user and the test it applies to.
3. The source, what part of it was read and the check date go into the numbered list under the page.
4. Where the research is thin, the table says “Not well studied” instead of guessing.

Guides are fact-checked against the cited sources. None is described as medically reviewed unless a named, credentialed reviewer has signed it off.

What we will never publish

No detox, flush, masking or dilution advice, no “how to pass” tips, no test-kit affiliate links, and no promise about any one person’s result. Time since last use is what studies show lowering a result.

The shop

A short shop sells hemp THCA flower by the half pound and the pound. Smoked, it produces THC and shows up on THC drug tests; every product page says so. The shop is reached from the header and never appears inside a guide. From December 11, 2026 it lists only flower that meets the federal total-THC hemp rule.
