When making cannabis butter strain out the plant matter pretty good. If you do it well enough and your butter isnt too potent you can have some space cakes that even a police officer would enjoy(probably be in the hospital soon after though).

Ive had some brownies that had virtually no weed taste at all. Man those things are dangerous. People were getting so high they thought they were dying, all because they underestimated an odorless brownie..
