I'd be really careful who you tell about your parents buying you alcohol. If it gets to the wrong person who tells their parent, your parents will be in deep poop for contributing alcohol to a minor.

Cough syrup and other medications that have that same effect can give you a drunken sort of feeling if taken inappropriately. So yeah, it can have that same effect as alcohol if going out in public and you get caught. A LOT of alcoholics who can't get ahold of real beer/liqour because of money, transpertation, etc, etc go for the other stuff... One man died a couple months ago from drinking a whole gallon of Pinesaw (sp?) because it was only 2 dollars at the dollar store and he didn't have enough for real booze. It happens...
