How unhealthy is smoking really?

Killed more people in the last century than all the wars combined.
That's pretty bad.

After researching it I've come to the conclusion that it's not unhealthy at all, certain groups that try to push a biased scientific view of smoking basically cherry pick the shit out of their studies and data, while completely downplaying the role that certain transmittable diseases have in causing so called smoking-related illnesses. It's called confounding by infectious disease.

Of course groups like the FDA and WHO don't ever want to consider this so they can claim shit like smoking or meat causes cancer.

Not the unhealthiest thing you could do, but pretty damn unhealthy.

Tobacco companies have actually been serving anti-smoking agendas for decades now. So I fail to see how the insult of me working for a tobacco company is supposed to work.

You are breathing in thousands of toxic, carcinogenic chemicals, just to get one that you are addicted to.

You tell me.

>tfw when i actually sincerely thought you were going to post some actual evidence for what you said. :(

also i hate when people start appealing to conspiracy because it contributes to exaggerated confirmation biases.

>A Newsweek cover story spread untruths about p53, cancer and smoking: "It's a cell's most elegant defender, a gene called p53. It stops tumors before they grow. But if damaged, it is involved in 60 percent of cancers." This is misleading. In the first place, the protein made by the p53 gene doesn't "stop tumors," it arrests a cell during its cycle of division, so that dna damage can be repaired. If the damage has been repaired, p53 protein levels decline, and cell division continues. If it has not been repaired, the p53 protein causes the cell to die. Most important, the p53 gene doesn't have to be mutated in order for it to fail to work. The action of its protein is blocked if cells contain the polyoma virus large T antigen, human papillomavirus E6 protein, adenovirus E1B 55KD protein, or hepatitis B X protein. Newsweek then spread hysteria about benzopyrene in order to blame smoking: "Most p53 mutations, though, are not inherited. Instead, they arise from a copying error or an attack by a carcinogen. Bulky chemicals, such as the benzopyrene in cigarette smoke, change G to T and C to A, for instance."

It's generally not a good idea to inhale anything other than oxygen.

You could research the amount of scam power put into making smoking look like a health risk, though. You'd be surprised.

if all you inhaled were oxygen you'd die. The air we naturally breathe from the atmosphere is mostly nitrogen.
