No no no, you feel it more if you EAT it, not SMOKE it. Its a piece of piss to make cannabutter.

Get some Herb, preferably the more the better. About a 1/4 will make a nice amount.
Get some butter. Obviously, DONT go and use a pound of butter with an ounce of Herb like some numpty did on here. I like to use around 10 grams of butter for 1 gram of Herb.
SIMMER in a pan for about 30 minutes.

EAT. Wait an hour. Be stoned for hours.
