What are some examples of alcohol abuse?

You mean some examples of affects of alcohol abuse:

When you drink too much alcohol, it goes to your brain and does some weird, crazy thing with the senses and the cells. Like when you see a drunk person, they're falling because their vision might be blurry, or they're dizzy, and so on. Also, it makes some people very violent. They will come home and possibly hurt their family all because some substance is triggering their brain senses to do so. Another thing it does, is it can make you completely black out so you don't remember ANYTHING that happened during the entire time you were drunk. There are even more, but you can go on google.com and type in alcohol abuse affects, and find more information.
