marijuana or alcohol? i first smoked in January, im 19 and i still havent had a drink, that answers it for me. however ill get drunk sooner or later just has to be the right time right place. never did a drug till i was 19 either haha! i was all against marijuana and then i got smart and realized its not that bad and has many positives. i know alcohol is bad for you in high quantities but i dont plan on doing it much at all so all good =).
