Here's the problem I have with this sort of thing. If you're so desperate to get "fucked up" that you'll stoop to drinking mouthwash, cologne and vanilla extract then what won't you try? Where is the line between recreational mind altering and plain self-destructive behavior? It's very dangerous. What most people don't realize is that any substance containing ethyl alcohol (ethanol, the same type of alcohol found in liquor) that is not intended for human consumption and therefore not controlled by the ATF is made with denatured alcohol. This is alcohol to which certain chemicals have been added to render it unfit for drinking, and are nearly impossible to remove. These additives can be toxic or can make one very ill. If the label says it contains something like "SD Alcohol #40", it's denatured alcohol. All the mouthwashes I've seen, including Listerine, are made with denatured alcohol and drinking them can have serious consequences, including death. Additionally mouthwashes may contain fluorides and other additives which also may be toxic. Fluorides, in particular are very poisonous in large amounts, which is why toothpaste packages warn against swallowing it. If you need so badly to get drunk or whatever that you're willing to risk serious illness or even death, then there are fundamental issues you need to address or else you may find your life on a downward spiral you cannot recover from. I've seen it happen, and it's never pretty.
