If smoking is really that bad for you, why is it that despite the nearly 9 decades of anti-tobacco research and government attacks on it, not a single scientist has been able to prove that tobacco causes cancer or COPD in even a single animal or randomized epidemiological study, thus forcing the entire consensus to rely on self-selected epidemiological data without controls for extraneous factors (and even then of course the evidence is weak at best, compare Japanese or Greek lung cancer or COPD rates to the very anti-smoking USA). Curious thing.

That picture is presuming that all the people are equally bad but instead you notice in real life all parties except for the white one are usually super dog shit at everything.

You really think government is anti tobacco? It gives them billions in taxes and keeps the population addicted and alive to sustain it.

well the lung cancer thing is more subtle but for sure tobacco smoking causes heart issues

anyhow it is proven that tobacco grown with industrial fertilizer causes the accumulation of polonium in the lungs and that’s bad. that’s why i only smoke cigs with organically grown tobacco

[Anonymous No.10380860]

oh also PS epidemiological studies of people who don’t smoke vs. cigarette smokers vs. smokers of cigarettes plus marijuana have shown that cigarette-only smokers have an increased risk of lung cancer over nonsmokers, but marijuana+cigarette smokers do not

It's not the fertilizer so much as all the chemicals they use to expedite the curing process.
If you do it the traditional way your tobacco leaves spend months properly drying and curing.
With the chemicals they use the months turn into days before you can start to put it into whatever tobacco product.
Tobacco itself isn't good for you, but they make sure its worse.

Easily. Objectively the purpose of life is to reproduce, if your seed is strong your daughters genes will dominate on her own children and your lineage continues. If the opposite case happens, you just improved your lineage by that much.

Other than that there is no argument to be had, men as well as women can refuse to procreate and in these modern days both do so on a regular basis based on various reasons, if anything the blame is on you for not bringing them up among traditional family-centered values.

they don’t use additives for drying i’m pretty sure
>The leaf’s journey starts in the ground and ends in a hot metal box, or “barn,” where the heat is cranked up to 165F so the tobacco dries in a way that preserves the leaf’s natural sugars and nicotine.

Unfortunately not the case for Indians. Look at all the mathematics tutorials on YouTube and you'll come across an Indian fairly quickly. I don't associate their accents with learning so it I usually close those tutorials out of boredom and search for anyone else.

This is derived from non-randomized epidemiological studies with ambiguities in their methodology, which captures people who already are at a higher risk for hypertension. The smoker's paradox of Japan, i.e the Japanese studies of 90s and 00s, which isolated for lifestyle and dietary factors, failed to show any increase in heart disease or even adverse cardiovascular events relative to the general population. It's a well known phenomenon that many smokers exhibit hypotension.
Tobacco smoke has pharmacological properties about it that would explain why both why such a paradoxical hypotension may be induced and the why the expected oxidative stress of the tobacco smoke on the the quick introduction to circulatory would be ameliorated:
1. Tobacco Smoke increases nitric oxide levels independent of nicotine, which exerts a vasodilatory effect.
2. Tobacco Smoke contains significant quantities of coenzyme Q10, which is very cardioprotective.
3. Tobacco Smoke contains MAO inhibitors, which, explain the paradoxical lower blood pressure in very heavy smokers; whereby norepinephrine is now partly displaced by octopamine, precipitating hypotension. Lastly, such studies as you mention consider any recent tobacco use within a given time-frame (generally a year) as a smoker; which, ignores the sudden compensatory consequences that quitting may inflict. Tangentially, terminating an MAOI therapy in most patients usually results in a transient increase in BP for a number of weeks to months (arising due to higher production of MAO enzymes in response to months or years of being inhibited). Any learned psychiatrist here who has used such pharmacotherapy can attest to this third phenomenon.

Link to this. The smoker's paradox I have read about is that the risk of malignancies is lower in Japan than elsewhere for smokers, which =/= no risk.

>It's a well known phenomenon that many smokers exhibit hypotension.
Many =/= all, and not having hypertension =/= not having atherosclerosis or hypercoagulability =/=/=/=/= not having greater mortality from one of the various things tobacco smoking does

> Lastly, such studies as you mention consider any recent tobacco use within a given time-frame (generally a year) as a smoker; which, ignores the sudden compensatory consequences that quitting may inflict.
And I suppose you have evidence of the clinically significant blood pressure increase and associated higher mortality, right? I'd love a chance to read it, thanks in advance
