> The stupidity that goes along with drinking, smoking, and doing drugs is just amazing.

People who do it to extremes are stupid, yes. But being drunk is an enjoyable experience, as is other forms of *cough* entertainment, as long as you don't do it to the extent of ruining your life and being dependant on it. For those with family histories of substance abuse problems, perhaps straightedge is a good solution. For most people having a drink or spliff is not going to do any harm.
