like they said weed only enhances your true personality, i can smoke a gram to myself before work and function like a normal person. if you are lazy, it makes you lazier. and if your stupid your just fucked, plain and simple. as far as actualy killing your brain, no thats all propaganda bs by the governmet. the real reason it killed brain cells is they pumped the test monkeys with 61 joints of "Columbian" strength marijuana in a period of 4 minutes. i'd like to see you hold your breath for 4 minutes and not kill some brain cells.
