There are some things on line I found about that. You can use the mouthpiece as a stirrer in a hot beverage of your choice : Tea, hot chocolate, etc. You could also let it build up and then fill it with alcohol pour it on a plate, and then just evaporate to have some oil. Remember to keep your vaped material. You only have a very small amount after each fill, but it adds up. All that CBD and some THC remain in there, and it is good to use for eating. I like it at bedtime.
