An eighth of weed is a measurement of cannabis weight, which is shorthand for one-eighth of an ounce, or 3.5 grams. Cannabis shops and dispensaries sell cannabis in a variety of different weights, the most common of which are grams, eighths, quarters, half-ounces, and ounces. An eighth of weed is the most popular measurement of cannabis, and it is enough to feel like you have plenty of weed at your disposal, but not so much that you feel like you have to rush and consume it before it ages. An eighth of cannabis will typically provide you with seven to ten bowls, depending on how big the bowl is on your pipe or bong. An eighth of weed can be anywhere from 2-4 nugs or buds of weed, and the only way to accurately measure an eighth of cannabis is by using a scale. An eighth of weed is a good amount to sample and perhaps share with a friend, and it is a great way to try out strains or share with a friend. The cost of an eighth of weed can range from $15-20 to $60 or over depending on the strain of cannabis.
