If you have a lot of weed, chop it in several batches.

If you’re using a shot glass, it’s okay to use a small pair of scissors like nail scissors or mustache scissors.

If necessary, stir the weed with the end of your scissors to expose large pieces that still need to be cut.

This works best with dry weed, but it may grind up sticky weed, as well.

Wash your coin or sanitize it with hand sanitizer, alcohol, or vinegar. This will keep germs from getting on your weed.

If the lid presses down over the bottle, simply push it down onto the container.

Use the same motion that you’d use to shake a maraca.

Depending on how thick your weed is, it can take a while to get your desired size. Expect to shake the container for at least 5 minutes. This method is safe and grinds effectively, so it’s a great option for every day grinding.

A coffee grinder is great for when you need to grind up a bunch of weed at once. However, it’s best to use dry weed because sticky weed may be harder to clean up. If you don’t get all of the weed out of the grinder, it can get mixed into your coffee beans.

You can also use an analog clock or watch to time the grinder.

Clean your coffee grinder thoroughly after you grind the weed so that your coffee won’t be spiked with THC.

You can use this method with either dry or sticky weed, though it’s best if the weed is dry.

If you think the pieces are still too large, rotate the cutting board so that you can easily slice the weed in the other direction. Then, make a second pass to chop it into smaller pieces. You can technically use any knife to cut up the weed. However, a sharp, non-serrated knife works best, especially for sticky weed.

Cut up your weed like you would chop up garlic or herbs.

This method works best for small amounts. Additionally, it’s a traditional way to grind up herbs.

It’s best to grind just enough for 1 joint at a time. If you’re grinding more, grind your weed in smaller batches.

Use a firm pressure as you grind the weed.
