perhaps some good ol' cannabutter?
Melt butter, add weed grounds, simmer for a while, strain, refrigerate, add to bagel/bread/anything else butter makes awesome
grind up herb into teaspoon, pour oil into teaspoon, cook up with lighter, filter and mix into something cool
Easier: just boil the weed in milk or soymilk for about 15 minutes.
About 1 gram per person should provide a strong high that lasts from many hours to a whole day, depending on personal sensitivity, tolerance, etc.
