This image of back-to-photos -- one of a woman holding a gun to her mouth, the other of a man smoking a cigarette -- pretty much says it all. The band may not have intended it, but the cover presents a morbid (albeit apt) metaphor: smoking is suicide.
Tumour of Soul, Tumour Necrosis Factor
Lords of Acid, Voodoo-U
This is the censored version of the Voodoo-U cover. The original depicted a graphic she-devil sex orgy. Still, the FDA could use this cover to convey the idea that smoking turns people into nasty little devils.
Black Sabbath, Born Again
...and the FDA could use this one to show that smoking turns people's babies into sickly little things, maybe even the anti-christ, or something worse...
Van Halen, 1984
...Like a smoking cherub that likes Van Halen.
Social Cancer, Krowbarz & Baceball Brats
This cover conveys so many anti-smoking ideas to me. One, it's hard to breathe when you're smoker (hence, the gas mask). Two, non-smokers won't want to hang out with you (hence, the band name, Social Cancer). Three, smoking cuts off oxygen to your brain, which could make you stupid (hence, misspelling the album title).
The Alkaline Trio, For Your Lungs Only
Looking at this thin, frail body X-ray all rendered blood red is a reminder that as humans, we're fragile and full of yucky fluids and stuff, and smoking only make our insides more gross.
The Beatles, Yesterday and Today
Another album cover that was censored. This original cover, known as the "butcher" cover to record collectors, depicts the Fab Four holding busted baby dolls and surrounded by meat slabs. Imagine the meats are your heart and lungs, and the babies are premature from mom smoking. Do you really want your lungs in Ringo Starr's lap, or decapitated children on Paul McCartney's shoulders?
Cannibal Corpse, Vile
We could have used almost any Cannibal Corpse album cover for this list, but Vile seems most fitting for an anti-smoking campaign. If you can get past all the guts hanging out, look at the device on the corpse's mouth - that's a dental device used to hold the jaw open when a patient is undergoing extensive dental work. And since smoking damages the teeth, take it as a warning: smoke, and one day, you could find yourself in a dentist chair, getting your rotten teeth pulled, while your guts fall out.
