I was told today by my modern history teacher that the company that made wine and liquor usually replace the liquid with substance that taste the same but cause blindness. So i just want to inform everyone about this even tho you don't drink and to those who do, make sure to check the bottom of the glass to if there is a hole. I was glad i was notify about this because I know at some point, i might want to try it out so just be careful to those who might try it out when they get older. (This was in my blog so I decide to move it to General Discussion because it is important)
