could call the cops yea but it'd be easy to dispose of once you see a cop coming. Also, if you smoke, and if there's a lot of people, they might smell it, but might not be able to pinpoint it.

As far as cooking, I'd worry more about stinking up your house than fucking up the brownies/cookies.

Penut butter, crackers and a microwave. And there you got some ganja snacks.

(hint, mix PB with weed and put on cracker or toast and then nuke)
