2 sturdy, heatproof glass jars with lids (i.e. Mason jars)
1 small jar
Large coffee filter
Electric Stove - NOT gas!
Grain alcohol (enough to cover the ground weed, plus an inch). For example, Everclear
1/2 oz (14g) of high-grade, 20%+ THC cannabis
Break down the cannabis with pestle in the sturdy glass jar
Pour the grain alcohol on the cannabis, adding an additional inch of liquid on top
Decarboxylate the cannabis by heating the jar in a large pot of water, until there are a few bubbles and movement in the jar
Cover jar with a lid
Store in a dark place for 72 hours
Remove the lid from the jar
Heat the jar in a large pot of water, until there are a few bubbles and movement in the jar
Slowly pour the liquid through the coffee filter into the second jar
Squeeze the remnants out of the coffee filter
Drive off the excess liquid by placing the jar into the large pot of water and heating on a Medium-Low heat (rolling bubble or simmer) for 15-20 minutes or so.
