A quarter of a lid? That’s one big doobie for man, one mellow high of longer duration but lesser peak activity, for munching.
Of course, I’m remembering vegatation from forty years ago. If what drug warriors say about weed of today is true, maybe a quarter ounce has that much bounce. If not, I’m thinking this guy isn’t the naif he claims to be, and the brownies triggered an acid flashback. Acid can indeed generate the sense of “I’ve just killed myself. Now I’m waiting to die.” Grass? Not so much.
