"Alcohol Abuse" is When you spill or dispose of any "good" alcohol. meaning if its still within its expiration date then it should not be poured down the drain or wasted for any reason, also known as a party foul.
your still young, you'll learn to like the taste of some beers.
i didnt have my first beer till i was 17, and i didnt like it all. for the remainder of high school i drank tequila, but have learn to appreciate the taste of beer cause i know the work that goes into some of the brands.
your pallet will develop with time, right now its probably best to just explore and find what you like the best
