i never heard about eating roaches... you cant eat weed raw... but if ur talkin bout cooking with weed you put it in a frying pan with some butter to extract the thc cause thc is fat soluble.. so ive heard. and you cook it till the butter turns greenish, put it in some brownies or spread er on some toast but it might taste pretty shitty haha. ull probally need quite a few roaches to get high from it tho. i also heard you can do it with vodka too but ive never tried it.

either that or save em up like other ppl said n smoke em which is wat i do.
