Here's what you do, dude.....

Heat up a mixture of milk and water on a pot on the stove. Make sure it's mostly milk. Bring it to a boil but make sure it doesn't boil over, then throw in your finely chopped weed. Turn down the heat and simmer for a while, then poor it into a cup and drink the milk and weed fragments. It'll hit you like a freight train, but not for a while.
