Folks, take a deep breath and calm down and debate the issue. If we can't debate the different sides without name calling, the thread will be shut down and warnings issued.
The term carcinogen refers to any substance, radionuclide or radiation which is an agent directly involved in the promotion of cancer or in the facilitation of its propagation. This may be due to genomic instability or to the disruption of cellular metabolic processes. Several radioactive substances are considered carcinogens, but their carcinogenic activity is attributed to the radiation, for example gamma rays or alpha particles, which they emit. Common examples of carcinogens are inhaled asbestos and tobacco smoke.

Im ashamed to admit that i am a smoker. I have tried to quit a few times but i keep getting sucked back into it. Smoking cigarettes have to be one of the worst things a person can do to their body. I know that the Govt makes huge amounts of money taxing them but it is at the expense of hundreds of thousands of lives a year. I really dont understand why we just dont outlaw cigarettes like we have every other drug.

We find it normal that asbestos is no longer used to build houses, that much money is spend on removing it from houses, polluting the air around people with asbestos is prohibited, yet poluting the air around people with tobacco smoke is not.
This activation of receptors by nicotine modifies the state of neurons through two main mechanisms. On one hand, the movements of cations cause a depolarization of the plasma membrane, which results in an excitation, particularly of neurons, but also by the activation of other voltage-gated ion channels. On the other hand, the entry of calcium acts, either directly or indirectly, on different intracellular cascades leading, for example, to the regulation of the activity of some genes or the release of neurotransmitters.

People talk about the freedom to smoke, and yet find it perfectly normal that we do not have the "freedom" to drive without a drivers license or to drive drunk.
Companies don't have the "freedom" to throw carcinogenic substances into the river nearby either.
We support those examples of limited freedom.
Why don't we support the example of limited freedom when it comes to smoking?
