Step 1

Step 1: Select a high-quality, THC-rich cannabis strain. Simpson recommends a relaxing indica strain, though patients are welcome to select any strain they prefer. A pound of flower will yield the entire 60 gram, 90-day treatment that Simpson recommends.

Step 2

Step 2: Place the entire pound of marijuana and one gallon of alcohol into your large bowl, mixing gently. After a few minutes of stirring, the THC will have almost fully dissolved into the solvent.

Step 3

Step 3: Pour the solvent, which may now have a green-hued color, through the cheesecloth and into your bowl. The marijuana material can stay in its bucket, it’s still usable!

Step 4

Step 4: Pour a fresh batch of isopropyl alcohol into the cannabis bucket, mixing gently in a repetition of step 2.

Step 5

Step 5: Repeat step 3, pouring this batch of solvent into the same bowl as the first batch. At this point, you’ve extracted virtually all the cannabinoids you can, so the marijuana material can be discarded.

Step 6

Step 6: Place your cannabinoid-infused solvent into your rice cooker. Technically, this step is optional; you could just let the solvent evaporate but using a rice cooker will significantly speed up the process. If you do not use the rice cooker, you will need to decarboxylate your cannabis first. Important: extraction solvents like isopropyl alcohol are flammable and care should be taken to avoid open flame when evaporating them.

Step 7

Step 7: Ensuring your rice cooker stays around 220°F, check the soon-to-be-RSO occasionally and wait until the solvent evaporation has finished. The final product should be thick and dark in color. At this point, remove your oil from the rice cooker using a syringe or spatula.
