I’ve seen a couple of videos like these pop up recently. Neither of these are altered in any way beyond simple editing. Maybe it’s just me, but it’s one of the grossest things I’ve ever seen. If you smoke, how can you possibly light up again after seeing this? If you don’t, how could you possibly start?

One line says it all: “So where does the brown go?”

Stephen Hawking wants you to quit smoking! Do it for the kids! Videos like these make me incredibly thankful that I can (soon) visit Chicago establishments without having to inhale that crap.

Luckily, for the absolutely recalcitrant smokers and denialists among you, who either feel an incredible urge to maintain the field of lung oncology, an intractable desire to poison yourselves, or both, for those of you who will go to every extreme to Defend Your Right To Smoke, there is good news! Recent scientific literature suggests that you can continue killing yourself, and enjoy it, all without smoking cigarettes. There you have it— cardiovascular mortality, hypertension, other circulatory issues, impaired cell death, breast cancer, lung cancer, pancreatic cancer, and diabetes—all in one convenient, easy-to-use package that doesn’t force those around you to smoke whatever you’re smoking. Enjoy!
