ithink alcohol is the worse of the two..... obviously since it can kill you, pretty easily and in many different ways, makes you do things you'd never do sober (like do fat chicks or fight huge dudes) it definitely has a negative effect on teen pregnancy since it makes girl spread they legs and makes it easy to rufi them...... this is not to say marijuana isnt bad.... cus ithink its right behind alcohol and this is coming from a smoker.... it makes you lazy, it takes your ambition away.... this doesnt seem like it matters at first, but as you begin to smoke more often, your ambition seems to leave for good and that is hard as hell to get back.... both are addicting, but the day after you drink, you'll be hungover but can still get stuff done and be normal... weed just instills the notion that nothing matters since weed makes you so happy and carefree.. take me for example, first year in university... gpa of 3.5....... start smoking a little too much... end of the next year.... F in every class ididnt resign from, if you knew me, this would sound unreal.. anyways, peole do drugs (including alcohol) because they work... they take you out of your mind, and believe me, most minds are bad neighborhoods and thats why people wanna be out of it for a bit.... overall, if you've never done any drug, isee you as a better person then me and i encourage you to never do any drugs.... its only a matter of time before something like that becomes a bad habit
