Since you only know of two ways to use tobacco, I think you need to
educate yourself on the subject at hand.
Before you attempt to educate me, read what you're linking to. How does one dip? How does one use snus? Holy ****. It's amazing. One requires you to spit, the other doesn't. Both are used in exactly the same way.
If by lethal you mean you won't smoke the same amount of weed a day as you will cigarettes, then yes. As I've illustrated earlier, those are only two of the ways you can use tobacco.
Even if you were to smoke weed as often as a person smokes cigarettes, it'd end up being less harmful purely because of the difference in the manufacturing processes between the two. But, as you pointed out, people simply don't smoke weed as often as they smoke cigarettes, making them safer still. Where the nicotine in one forces you to smoke often, and as the dosage of a single cigarette no longer suffices, weed is still there, standing strong, unless you smoke 10 times a day, every day. At that point, you're the exception, and not the rule.
What kills you is introducing toxins to your throat, lungs, and bloodstream. Ingredients depend, but see, smoking in general is known by every doctor out there to be bad, because only a select number of simple substances can oxidize (burn) and not produce carcinogens as a result of an incomplete reaction.
Any smoke you inhale that is made from an organic substance is likely bad for you. The amount of damage depends vastly on how often you inhale it and what kind of carcinogens and irritants the smoke contains. Without having at least three sources (none of which coming from your lovely legalise-pot sites, but rather educational facilities and whatnot) verifying that cannabis magically releases none or extremely few carcinogenic substances when heated, your argument lacks weight. I'm not saying smoking cannabis is worse than smoking cigarettes; I'm saying it's not harmless, and you can't compare the two in terms of lethality alone. You have to add in addiction (which according to recent studies is mostly attributed to habit in the case of nicotine anyway) for smoking tobacco to be far more dangerous than smoking cannabis.
Toxins found in cigarretes:

But surely Marijuana must contain toxins as well when you smoke it! Absolutely:

But wait a second...how about chewing tobacco and dip?

Aww ****!
But marijuana is still harmful if you smoke it so....oh wait. I guess I just won't smoke it:

And that's just from 03.
So...it's like, if I want to use smokeless tobacco, I'm ******* myself, and if I want to smoke, I'm ******* myself, but if I just inhale THC, I'm good to go.
Fantastic.
I'm pretty sure that if I smoked forty pure-cannabis cigarettes a day for thirty years, I'd have some kind of lung problems (among others) as well as whatever else the different carcinogens will do to your body.
As to 'special ingredients', I would really like to know how you can be sure that all the dealers of America don't put anything in your weed.
I'm sure the average marijuana user smokes 40 times a day. Its totally normal behav....wait a second. No. No it's not, so the comparison is disingenuous. I'm sure if I drank a pint of water 30 times a day I'd end up messing up by body, too. But, you know, that doesn't really happen. That's the problem with hyperbolic statements. It makes everything ridiculous.
Find me a dealer who waters their plants with uranium-laced water and we'll talk.
A lot of people who smoke cigarettes also smoke weed. Because of this fact, you can't know if cigarettes are the main cause of all the cancers it has been attributed to it. Besides, as I pointed out earlier, it's not like you smoke forty weed-cigarettes a day. I'm pretty sure I wouldn't get cancer from smoking five cigarettes a day for the rest of my life - odds are the air and the chemicals in my food and water will get me first.
A lot of people who smoke cigarettes don't smoke weed, too, so you study them and see what happens. And what happens 1 out of every 5 times in the States is a tobacco-related death. The stats are there for all to see.
On a sidenote, why is it so bad for people to die five to ten years before their time? We have enough old people, and there will only be more of them. Who's going to take care of us when we're all a bunch of arthritis ridden 98 year olds?
Much like the rest of your post, this last statement is preposterous. I'd rather die of old age than lung cancer, or have my lower jaw removed because I chose smokeless tobacco as my drug of choice.
