If you're new to cannabis or just have a hard time visualizing 20 grams of weed, we can help. Twenty grams is not quite an ounce (28 grams) but still a considerable amount of weed. Here's everything you need to know about buying and using 20 grams of weed.

Understanding the Metric System and Dispensary Weights

When buying weed, you will need a basic understanding of the metric system, also known as the International System of Units (SI). This is not the primary system of weight measurement in the United States. We usually use units of pounds, ounces, and tons to weigh things.

In the metric system, used by most people around the world, they use units of milligrams, grams, and kilograms to weigh things. Grams are used for weighing smaller objects, while kilograms are used for larger amounts.

At a cannabis dispensary, you'll commonly see cannabis flower sold in metric units:

  • One gram: One gram is the lowest amount sold at dispensaries. It can be enough for a medium-sized joint or a couple of bowls. Also known as a dime bag back in the day and in the illicit market, a single gram can cost between $10 and $20, depending on its quality.
  • One eighth: An eighth of weed is 3.5 grams, or sometimes 5 grams if the dispensary is running a special. An eighth can be good for about 3 to 6 joints. It can run you about $20 to $60. Buying in bulk is more cost effective than buying a single gram at a time. However, you can try out new strains by buying single grams of them at first.
  • Quarter ounce: A quarter ounce equals seven grams. It is also known as a quad or a quarter. A quarter ounce can fill about 14 joints, costing $60 to $90.
  • Half ounce: A half ounce, also known as a half or a half-o, is 14 grams and can fill about 28 to 30 joints and cost $100 to $150.
  • Ounce: A full ounce is 28 grams and can fill about 60 joints. An ounce costs anywhere from $150 to $350 and higher.

Dispensaries usually round down when measuring eighths, quarter ounces, half ounces, and ounces. For example, an ounce is technically 28.3495 grams. Dispensaries will round down their ounces to 28 grams.

The amount of weed you can buy at a time depends on your state’s medical or recreational cannabis program. For example, California adult residents can buy up to an ounce of weed. In Illinois, adults can buy up to 30 grams of weed.

Under Florida law, possessing 20 grams or more is a felony conviction punishable by a maximum $5,000 fine and five years in prison. Possession of 20 grams of less is a misdemeanor marijuana possession charge.

What Do 20 Grams of Weed Look Like?

Twenty grams of cannabis flower is about 71% of a full ounce. The appearance of 20 grams depends on the material's density, structure, and overall quality. Some cannabis buds are light and airy, while others are compact and dense.

How Much Does 20 Grams of Weed Cost?

The price of cannabis flower depends on various factors, including where you live, whether you’re a medical or recreational user, the time of year, and the quality of the flower. Twenty grams of shake can run you as low as $30 or up to $300 or higher for high-quality bud.

How Long Will 20 Grams Last?

Twenty grams of weed can last a decent amount of time, depending on your frequency of use and how much you use at one time. For example, 20 grams of cannabis can last a day at a large gathering. However, it can last weeks or months if you use it sparingly for personal use.

What Can You Do with 20 Grams of Weed?

Twenty grams can fill about 40-45 joints with about half a gram in each joint. It can pack about 34 bowls. It’s also enough to make several batches of cannabutter or canna-oil, which can replace regular butter and cooking oil in many recipes.
