Well, damn. It looks like I need to put down the beer and pick up the crack pipe. It'd be less harmful, according to a study by Brittish professor David Nutt. (Which invites a lot of beer addled puns...)
Apparently, alcohol causes the most harm to the self and others of all the brain chemistry altering substances one can be arrested for using while driving. Although there is controversy over the "harm-ranking" system by which he came to this conclusion, Prof. Nutt has come up with a very convincing graph.
