I did brownies this weekend with canna butter i made from lower leaves that fell off two weeks into flowering, i figured it wouldnt work since the potency had to have been so low..... So i make them, 3 hours later, nothing, 4 hours later just when i was thinking they were worthless, i started feeling it, 6 hours later....Holy Fuck!!! I didnt reallize it takes to long for brownies to digest and kick in, but man i am never smoking again. All cooking now on. I cant believe you can get that high, plus no dieing lungs in the morning.
