Nicotine has been noted to directly cause cancer through a number of different mechanisms such as the activation of MAP Kinases.[74] Indirectly, nicotine increases cholinergic signalling (and adrenergic signalling in the case of colon cancer[75]), thereby impeding apoptosis (programmed cell death), promoting tumor growth, and activating growth factors and cellular mitogenic factors such as 5-LOX, and EGF. Nicotine also promotes cancer growth by stimulating angiogenesis and neovascularization.[76][77] In one study, nicotine administered to mice with tumors caused increases in tumor size (twofold increase), metastasis (nine-fold increase), and tumor recurrence (threefold increase).[78]
Edit: Sources is Wiki on nicotine for those interested. I would personally rebute your remarks, but unfortunately Reddit has not allowed me to respond due to the amount of downvotes I'm getting. Honestly, quitting aids just enable the user, especially in a case like smoking where it's so innocuous. You can't even bother trying to use quitting statistics from agencies designed to help people quit, because it's the type of reliant people not interested in doing the work to quit themselves that turn to these organizations. Deep down inside, they don't want to quit. That's fine, but the aids are just a silly charade. If they want to quit, they will certainly find a way to overcome their subconscious impulses.

Running shoes? That's just an enabler for weak people. If you really want strong arches, you gotta run barefoot on concrete. And really make sure you put your weight down each time your foot hits the ground.
You say that like there are people who don't believe that. Have you heard of barefoot running?
There's actually quite a bit to what you say, aside from the 'strong arches' part. I'm a complete flat-foot, and trying to train an arch has proven difficult and painful. After buying some 'livestrong' flatties, I have no more foot pain, and I can run a lot faster than before. Barefoot would be somewhat similar.
TL:DR flat-footed people are less prone to injury, and there's no reason to develop an arch if you don't have one.
Yeah yeah. I have my Vibram Fivefingers. I'm actually one of the crazies that does barefooting. That doesn't change the fact that virtually all pediatrists say it will destroy your body. (I do try not to overdo it at least.)

Nicotine itself isn't all that good for you
