Medical marijuana users have just succeeded in striking down the portion of the law limiting use to smoking it in Canada. Here is how to make your own butter:
Take a known amount of pot, eg enough to make 20 joints and put it in a large pot filled with water. Drop in a pound of butter and bring to pot to a boil. Simmer for several hours then it sit to cool. Put it in the fridge overnight. In the morning you'll have a layer of butter on top. take it out, clean the scum off the bottom. You can use it now but it will taste pretty awful and it comes out in small pieces. I put it in a small tall pot of water and bring it to a boil again then let this cool and put over night in the fridge. In the morning you will have a fairly pure easy to clean puck of butter. Use it in place of a portion of the butter in a recipe. My Walmart Brownies almost hide the strong fodder taste of the butter. From the number of joints you started with you'll know about how many portions to make with the butter.
