An “8th of weed” is a common cannabis weight: it means one‑eighth of an ounce, which is about 3.5 grams of cannabis flower.

What an 8th of weed means

  • An eighth is shorthand for one‑eighth of an ounce of cannabis.
  • In metric terms, that’s typically 3.5 grams of weed.
  • It’s one of the most popular purchase sizes at dispensaries because it’s enough for multiple sessions without committing to a large amount.

How much actual weed that looks like

  • Depending on bud density, an 8th might look like roughly 2–4 medium‑sized nugs.
  • For many people, 3.5 grams can last anywhere from a couple of days to a week or more, depending on how often and how much they use.

Quick measurement cheat sheet

Here’s how an 8th fits into other common weed measurements.

  • 1 gram ≈ small personal amount
  • 1 eighth = 3.5 grams = ⅛ ounce
  • 1 quarter = 7 grams = ¼ ounce
  • 1 half = 14 grams = ½ ounce
  • 1 ounce = 28 grams

Small safety note

  • Effects and risks depend on THC strength, your tolerance, and how you consume it; starting with small amounts and going slow is generally safer, especially for newer users.
  • Always follow your local laws and age restrictions around cannabis use and possession.
