A new study had shown that examined traffic fatality statistics across the country (USA). the main reason is that marijuana is consumed differently then alcohol so the your motor senses are more responsive then when your drunk. your mind my be a little weird when your high but when you drink its a lot worse. The study has shown that being high and driving is 10 TIMES SAFER then drinking and driving. Still don't do either because for one there both illegal and still dangerous and its bad for your health.
