What this means

  • The listed THC is not out of line with similar products, and nothing we hold contradicts it.

What it does not mean

  • This is not a lab test by GLASS. We only read what stores and their menu platforms publish.
  • A listing can differ for many reasons: a new batch since we recorded it, THCA shown as THC, a typing error, or a platform quirk.
  • It says nothing about the store, the brand or why the number differs.
