i am not a doctor, i took two semesters of biology in college against my will, but my understanding is that cigarette smoke is just very finely aerosolized tobacco bits, and this causes irritation to the mouth, throat, and lungs. this irritation is actually damage that the cells, and after a sufficiently long enough time or sufficiently bad luck, the cells repairing themselves can become damaged enough that they fuck up when trying to fix themselves and you get cancer

high rates of mitosis in lung tissues frequently create defective cells which can become cancerous. dozens of chemicals in cigarette smoke which aren't supposed to be in your lungs interfere with a cleaning process that would otherwise be effective at removing them.

Because when you set something on fire, a lot of the products of combustion are truly carcinogenic.
How could breathing in carcinogens be bad for me lol???
Also your breathing gets impacted if you smoke enough and you feel like an asthmatic child every day, that can't be good for your heart.
Thankfully every drug that needed to be smoked can be eaten and / or vaporized now.

2. Makes you seem low class/retarded.
3. Makes your teeth and nails yellow and disgusting.
4. Brings respiratory problems. Enjoy panting like a dog when you take a walk.
5. Expensive. If you smoke long enough you WILL inevitably start smoking a pack a day, which costs about $5-10 a day, which gets pretty expensive.
6. Makes you anxious when you haven't had a smoke in a while. Inconsistent mood.
7. Not allowed in a lot of places and countries.

There are many carcinogens in tobacco smoke that are known to damage cell DNA, and if the tumor suppressor genes in DNA are damaged, it can lead to uncontrolled cell proliferation and cancer. Mutations in the TP53 gene are found in about half of all human cancers.

Smoking also suppresses the immune system, and the immune system is what essentially cleans up damaged cells.

decided to add the description:
> Mutagenesis by Bulky Addition Products
> Benzo(a)pyrene, a chemical produced by internal combusion engines and thus common in the environment, is not itself mutagenic. However, in the mammalian liver, benzo(a)pyrene is metabolized to diol epoxide, which binds covalently to guanine bases, preventing proper base pairing with cytosine bases. Bulky Addition Products such as diol epoxide or Aflatoxin B1 may result in depurination mutagenesis and are known to be carcinogens.

You probably know it from movies.
There are some scum in the upper class, but the trend is obvious: in russian prisons everybody smokes, and world leaders are almost never seen nervously clinging to a cigarette, I cannot even remember a photograph of them socially smoking. Some wannabe politicians, maybe, but not being stronger than their habit is not helping.
What will you do, if in some society you're forced to take your cigarette outside? Your habit would make you constantly humiliated. The shit they print on the cigarette packs only supports this claim that tobacco is a humiliation ritual (you may bully some weaker "friend" by smoking into his face, but in the end you're the bitch.

not him, but damage requires repair. Too much damage, gone on for too long, without being addressed, can lead to corrupted DNA inside of a cell. If a certain gene switch is flipped which regulates its reproductive cycle, then it will continually reproduce without stopping. If the DNA is corrupted and that gene that is telling it to replicate itself (or more likely a combination of genes) will no longer turn off, then it will just reproduce forever and keep growing and turn into a visible tumor. That's all cancer is, corrupted cells that never stop reproducing.

It's true that most smokers won't develop cancer, though many die relatively young from other smoking-related conditions like COPD and CVD.
It's also true that most people who develop lung cancer aren't smokers.

However
Smokers have a 25x higher risk of developing lung cancer than non-smokers.

>Explain scientifically why smoking causes cancer.
When an individual smokes, they are breathing in a mixture of molecules. These dissolve into the surfactant coating the surface of the lung and then pass through into the blood.
The nicotine which enters the blood goes to the brain and binds certain cell-surface protein receptors, leading to the pleasurable effects of smoking.
Many of the other molecules in the blood, from the cigarette, enter cells and undergo chemical reactions with DNA to form DNA adducts (a form of DNA damage).
This DNA damage can lead to cells becoming cancerous, by interfering with genes coding for things like tumor suppressor proteins (such as p53, which is found to be mutated in >50% of cancers)

Tin foil hat hypotheses: Most of the harmful effects come from all the chemicals and additives. Cancer didn't rise until cigarettes stated being mass produced.
Bigger tin foil hat hypothesis: Cancer started spiking after the nuclear tests through the 1950s and the government picked big tobacco as a scapegoat.

I smoke organic additive free tobacco and I roll it in unbleached rice gum, and even then it's only 1 or 2 a week.

Glad to see /sci/ hivemind has prevailed with my 4chan benzopyrenes hypothesis over the reddit DUDE TOBACCO HAS RADIOACTIVE SHIT IN IT AT 1PPT (despite all other plants and bioaccumulation of animal meat having this at far greater quantities and much more likely to be taken up by the body when ingested orally). On the bright side, smooth brains, avoiding first pass metabolism by inhalation of the benzypyrenes is ironically much less carcinogenic than eating them so in reality the bigger take away should be that you shouldn't oversear your meat and don't eat anything heavily burnt like blackened toast or burned pizza.
