Hahah See you can drink listerine (****AS LONG AS IT HAS NO FLUORIDE IN IT****), and you can drink vanilla extract. I've drank listerine. It has Alcohol in it. Other things with alcohol in them are not good to drink! They usually have SD (specially denatured) alcohol in them. This means the alcohol in their product has things added (things like petroleum products, isopropyl alcohol, methanol) to it to make it poisonous and undesireable to drink. As far as i know Listerine mouthwash doesnt have SD alcohol in it. And if it does, it does not have nasty things like methanol and isopropyl alcohol in it so you will not go blind if you buy regular plain listerine with no fluoride in it. Always read the package to make sure there is no fluoride in it! Fluoride is extremely deadly and toxic!!!! BAD VERY BAD!
