Ganja Grams

A gram is a gram, but Canada's thirty-gram limit is not thirty grams of everything. What each quantity term means, and how the law converts between dried flower, edibles, concentrates and the rest.

What the quantity terms mean

1 g

Gram

a "dime", a single
3.5 g

Eighth

an eighth of an ounce
7 g

Quarter

a "quad"
14 g

Half

a half ounce
28 g

Ounce

an "O", a "zip"
112 g

Quarter pound

a "QP"

An ounce is 28.35 g, universally sold as 28. Anything advertised as an ounce that weighs meaningfully under 28 g is short, and scales are cheap — weigh it.

These figures are set out in Schedule 3 of the federal Cannabis Act, and the 30 g public possession limit applies to adults. Provinces add their own rules on home storage, public consumption and minimum age, and they differ substantially. This is general information, not legal advice — check your province.

How we write

Legal figures here come from the federal Cannabis Act as it currently stands; legislation changes and provinces vary, so verify anything you intend to rely on. Where a shop we link to is one we have a relationship with, that is disclosed. General information, not legal advice.
