Regardless if you are planning to get wasted or not use a plastic cup.

Now I'm only telling you this because I learned the hard way. After god who knows how much Gin in my drunken state I knock the glass off the table and it shattered. I don't remember shattering a glass and I also don't remember getting cut. I seemed to have slashed my foot and took a piece of skin off my thumb's knuckle. I was lucky. I could have cut myself real bad and died from lack of blood. So for now on I know I'm going to use a plastic cup incase I accidently ever get wasted again heh.
