8 grams cannabis
750 milliliters (a fifth) of light 80-proof rum
Grind the cannabis and add to rum.
Store in a cool, dark place for 4 days, shaking vigorously every day.
On the fourth day, boil a large pot of water. Once it's boiling turn off the heat and sit the sealed bottle of rum in the hot water for 30 minutes. The water level should not cover the top of the bottle. Psychoactive ingredients in the cannabis will activate and infuse the alcohol.
Strain the vegetable matter out of the rum.
Discard the leaves and use the rum to make your favorite cocktail!
