Warning labels

Cigarettes have warning labels.
These often graphic depictions of blackened lungs, gummed up aortas, or even amusing little limp cigarretes to show how smoking increases erectile dysfunction; are supposed to stem the tide of new smokers, and help convince habitual smokers to quit. As far as I can tell, these graphic pictures have not had the desired effect; they have not halted smoking, they have not stopped new smokers form starting, and often, smokers collect the boxes, in an attempt to collect the whole set.
Now, I digress. The purpose of my little rant is to ask, why smoking?
Why has smoking alone been targeted for this campaign of graphic deterrant images?
I maintain that as long as one social issue is being targetted (smoking and the concurrent health issues) why not others?
Every bottle of Jack Daniels should have a picture of a wife with a black eye, every pack of beer should have a picture of a puddle of vomit and urine in a sleazy bar's mens-room, and every bottle of sambuca should have a picture of a drunken italian knife fight. (ps. This does not constitute an attack on any of the above mentioned brands of products...we LOVE them all.)
But fair is fair.
Liver damage, domestic abuse, fatal car accidents, and splitting headaches all link to alcohol use; why then has the government attampted to regulate cigarettes and not drinking. Now, I don't support the government heavily regulating it's citizens, or living in a repressive closed society, but I would like a government who is genuinely interested in the well being of it's citizens and regulates the products available to us with a fair hand, not picking and choosing what it likes and doesn't like.
All I wish is that either the government would cease to use this negative imagery on packaging, or that they would consistently apply it to all potentially harmful products- that and find a way to get rid of this pounding headache and hangover...
Adieu.
