Is an Eighth Enough for Brownies? A Complete Guide

Cannabis brownies are one of the most popular ways to consume edibles, but a common question is: Is an eighth enough for brownies? In this guide, we’ll break down how to use an eighth of cannabis in brownies, calculate potency, and provide tips to make sure you’re getting the right strength for your batch.


What Is an Eighth?

An eighth refers to 3.5 grams of cannabis, a common measurement used in both smoking and making edibles. While 3.5 grams might seem small, it can be potent when making edibles. Proper decarboxylation is key to activating the THC. Without this process, your brownies won’t have the psychoactive effects you’re looking for. You can read more about proper decarbing in our guide on how to make edibles.


The Science of Cannabis Edibles

When you consume cannabis through edibles, it’s metabolized differently than when you smoke it. This results in a much stronger, longer-lasting effect. An eighth of cannabis is often enough for a small to medium batch of brownies, but if you’re unsure how to adjust for strength, check out our guide to measuring cannabis dosage for edibles.

Calculating Potency

To figure out if an eighth is enough for your brownies, you’ll need to calculate the THC content:

  • An eighth = 3.5 grams of cannabis.
  • With a THC content of 15-20%, this translates to around 525-700 mg of THC.
  • Divided into 12 brownies, you’re looking at about 40-60 mg of THC per serving.

For most users, 10-20 mg of THC per serving is considered moderate. If you’re new to making brownies, explore more tips on how to make the perfect batch for adjusting dosage and texture.


How to Make Brownies with an Eighth

Here’s a simplified version of how to make potent brownies using an eighth:

1. Decarboxylation

Start by decarbing your cannabis. Learn more about the decarbing process in our article on decarboxylating cannabis for edibles.

2. Infusing Cannabis into Butter or Oil

Melt butter or heat oil and infuse it with the decarbed cannabis. Strain out the plant material, leaving behind the infused butter or oil. Get more detailed instructions on infusing cannabis in our guide here.

3. Baking the Brownies

Once your butter or oil is ready, use it in your brownie recipe. For more ideas, check out our favorite cannabis brownie recipes.
