Yes and it's a pain in the butt! The best way I know is using keif, 1 gram of keif per 1 ounce of honey. Pour into a jar and put it in the closet. Open the closet and shake the jar every morning and night. After 30 days remove and put the jar into a crock pot with water. Leave the top on the jar until the water is hot. I use tongs and pull the jar, drop a 2-3 bowls into the crock pot and now set the jar into the bowl with lid off. Bowls should raise it up in the water so it won't tip over. simple heat until the honey holds 170'f for 5 minutes. That also sanitizes it in case you have contaminated it in some way. You can also do glycerin the same way. I have heard of people using buds with mixed results. I prefer this method as you can put a few drops under the tongue rather than suffering the losses of digestion. Enjoy! Please always make sure you are using kosher food grade glycerin so that no one dies! Some forms of glycerin are poisonous to people, so don't run to Walmart. Their dumb butt pharmacist was trying to tell me it was safe. Why does it say keep out of the reach of children and poison control numbers on it, cause it's deadly. Don't listen to so called professionals with cannabis, ask a hippie!
