yo you need alot more than 20 bucks worth. for a big ol batch of chocolate chip cookies i would say at least, AT LEAST a fat eigth. when you cook with wweed you wanna use alot, like for brownies you would use even more, probably a half or so. i can only imagine what thatd be like. puttin a half of nice bud into chocolatey goodness. i bet it gets you ripped too. i never did it myself, just dont got the resources. i just know 20 bucks worth aint gonna do it, it will get diluted and youll just have funny tasting cookies.
