RSO is a marijuana extract that contains high levels of THC and other cannabinoids. It is usually made with a solvent like ethanol or isopropyl alcohol. To make RSO with Everclear, high-proof grain alcohol, you will need the following: Cannabis buds or trimmings Everclear A glass jar with a lid A coffee filter A rice cooker A syringe or dropper bottle The steps are as follows: Break up the cannabis material into small pieces and place them in the glass jar. Pour enough Everclear to completely cover the cannabis and close the lid. Shake the jar vigorously for a few minutes and then let it sit for a few hours or overnight. Strain the liquid through a coffee filter into another glass jar and discard the plant material. Transfer the liquid to the rice cooker and set it to the lowest heat setting. Let the alcohol evaporate until you are left with a thick, dark oil. This may take several hours depending on the amount of liquid and the temperature of the rice cooker. Turn off the rice cooker and let the oil cool slightly. Use a syringe or dropper bottle to collect the oil and store it in a dark, cool place. You have just made your own RSO with Everclear. Be careful when using this oil as it is very potent and can cause psychoactive effects. Always consult your doctor before using RSO for medical purposes.
