What Is an 8th of Weed? Cannabis Measurements Explained

If you are new to buying cannabis, the vocabulary can be the confusing part. An eighth is the quantity you will see quoted most often. Here is what it means and how it sits against the other measurements.

What an 8th actually is

An eighth is one eighth of an ounce. An ounce is roughly 28 grams, so an eighth is about 3,5 grammes. That is where the name comes from — nothing more complicated than the fraction.

Cannabis measurements side by side

• Gram: the smallest unit normally sold, roughly a twenty-eighth of an ounce.
• Eighth: one eighth of an ounce, about 3.5 grams.
• Quarter: one quarter of an ounce, about 7 grams.
• Half ounce: about 14 grams.
• Ounce: about 28 grams, the largest of the standard retail quantities.

Why the eighth became the standard

It sits at a useful point on the scale: enough to try a souche properly across several sessions without committing to a larger quantity. That makes it the natural unit for comparing one product against another, which is why prices are so often quoted per eighth.

Comparing prices sensibly

Because the eighth is a fixed weight, it is the cleanest basis for comparison. Work out the price per gram and the picture usually gets clearer still — larger quantities normally carry a lower per-gram price, so an ounce is rarely eight times the price of an eighth.

What to check before you buy

• The listing itself: strain, format and the options available.
• Cannabinoid figures: THC and CBD content vary between batches, so read the numbers given for the specific lot.
• Price per gram: the fairest way to compare two products of different sizes.
• Storage: once it arrives, keep it sealed, cool and out of direct sunlight.
