Vegetable glycerin is safe to eat and doesn't taint the taste of food. With minimal effort and a small amount of time, you can make your own cannabis-infused vegetable glycerin that can be taken sublingually or added to your favorite dishes. 

Vegetable glycerin is found in a wide variety of foods, proving more common than you may think. It is merely the byproduct of compounds made in manufacturing, but due to its mild taste, it can be added to a broad spectrum of food and drink without tainting the flavor and provides a highly effective way of making edibles with minimal fuss.

The best part is, if you don’t want anyone to know, they won't. It is one of the most discreet ways to ingest cannabis.

The only “watch out” with vegetable glycerin is that because it is the byproduct of artificial compounds and a result of the manufacturing process, the integrity and quality can vary from producer to producer. So make sure you purchase it from a reputable source to guarantee a quality product.


  • ½ ounce (14g) cannabis buds (broken up into smaller pieces)
  • 2 cups vegetable glycerin


  • Parchment paper
  • Slow cooker
  • Mason jar
  • Oven gloves
  • Dropper bottles
  • Small bowl
  • Cheesecloth
  • Washcloth
  • Funnel


1. First, you need to activate the THC within your cannabis buds by decarboxylating them. Place the buds on parchment paper on a sheet tray, and heat them in an oven at 104–112°C (220–235°F) for 40 minutes.

2. Using the mason jar, combine ½ ounce of decarboxylated weed (strain of your choice) with two cups of vegetable glycerin. Shake thoroughly to ensure both ingredients are completely mixed. All the bud needs to be covered in glycerin.

3. Set the slow cooker to “warm” and line with a folded washcloth. Fill halfway with warm water, before placing the mason jar inside the slow cooker. Secure the lids of both the mason jar and slow cooker.

4. For the cannabis to fully infuse with the glycerin, you will need to leave the mason jar for 24 hours. Ideally, you should remove the lid and stir the mixture every couple of hours to maintain the liquid consistency.

5. After 24 hours, carefully remove the mason jar using oven gloves. Unseal the jar and leave to cool for at least an hour. Placing the jar in the fridge can speed up this process.

6. Once cooled, strain the vegetable glycerin into a small bowl using the cheesecloth. Be sure to save the larger bud pieces that remain; these can be used later. The liquid in the bowl can then be transferred to dropper bottles using the funnel.

7. With your dropper bottles filled, your cannabis-infused glycerin can be taken sublingually under the tongue, or added to food whenever needed. The leftover buds can be infused into tea or coffee for an uplifting hot drink; waste not, want not.
