Place the ground beef in a skillet over medium heat. Cook and stir the ground beef while breaking it up as it cooks. Do this until the ground beef is fully cooked, around 10-15 minutes. Drain all of the grease
Turn the heat to low and add the cannabis butter. While the cannabis butter is melting add in the taco seasoning. Stir constantly. Continue stirring until the seasoning has been fully incorporated.
Mash the refried beans with the water in a small saucepan. Heat the refried beans over low heat until simmering.
Preheat oven to 300 degrees F (150 degrees C). Place the crisp taco shells on a baking sheet, and warm them in the preheated oven for 3 to 5 minutes.
To build the tacos, spread each taco shell with about 2 tablespoons of heated refried beans. Spread about 2 tablespoons of ground beef along the bottom of the crisp shell, and sprinkle about 2 tablespoons of shredded Cheddar cheese on top of the meat. (Make sure you are not straining the melted butter when doing this) Top the cheese with shredded lettuce, a sprinkle of chopped tomato and onion, and a tbsp (or more) of sour cream
