With all the public banning of smokers, they'd be a nice club to join. It's a social activity and commonality that I believe would be very useful.

I don't smoke, but will go on smoke breaks with other people at work. You make friends. I'd expect it to be more generally useful to be able to join the little smoking islands in public.

Well, those particular two aren't actually less dangerous to me, on account of a latex allergy.

(I don't know if the gum -actually- contains latex, but it sure as hell tastes like it. Problem there is that nicotine tastes like an allergic reaction to me; both "taste" like needles stabbing into my tongue. Either way I'm staying well away from the gum, and using the patches, which merely cause me skin irritation, sparingly; mostly I use them for lucid dreaming, as they're the only reliable mechanism I've found for inducing strong dream states.)

Trying to get accustomed to e-cigs, but they're pretty harsh.

You also stink up the present. Smoke breath is a type of BO.

primarily via cancer.

Also heart disease, stroke, and emphysema.

I discount that for several reasons - first, I'm not guaranteed to survive to that point. Second, lung cancer survival rates continue to improve (it's still a minority that survive, mind, but over my lifetime I expect that figure to improve still further). Third, lung cancer is a pretty predictable mode of death - in terms of cryogenics, my really long-term survival could be considerably improved over other, less predictable forms of death, such as heart attack or stroke.

Additionally, two cigarettes a day for 10 years produces only a marginal increase in health risk. In fact, you have to consume 5 pack-years (1 cigarettes a day for 20 years is a pack-year; the relationship is strictly linear with both respects, so 1 cigarette a day for 40 years is 2 pack-years, and 2 cigarettes a day for 10 years is 1 pack-year) before you start to see substantial health risks from smoking.

At present, I consume 1-3 cigarettes a day, and skip many days, and frequently skip weeks. (I am currently using them to try to train good behavior into myself.)

I will also add that smoking reduces my sinus response to allergens quite considerably, which has reduced the number of sinus and chest infections I get, as well as the severity when I get them. (This is apparently at odds with what most people experience, but it's been consistent my whole life - when my parents stopped smoking is approximately when I started having severe allergy problems.)
