Is an Eighth the Right Amount for You? What to Expect

A good fit if…

  • You're a regular user – An eighth gives you about 7 joints or several bowls, enough for a week or more of moderate use.
  • You want variety – You can buy a couple of eighths of different strains without overcommitting.
  • You're on a budget – An eighth is a cost-effective way to buy more than a gram without paying ounce prices.

Consider another option if…
