Do people know smoking is bad for them?

Most smokers, especially those over a certain age and who have been smoking for a long time, are fully aware of the health risks but find it impossible to stop, despite dearly wanting to. It's an incredibly powerful addiction.

I do not know who invented this killer stick. I do not smoke but I know most people that smoke do so because they claim they derive some satisfaction from the nicotine that is in the pack.Over time they become addicted and it become really hard for them to quit the habit. Many smoker are ignorant of the medical risk that await them. However, there are people who are aware of the danger but they keep smoking never minding the risk. I think we have the ignorant smoker and those who are aware but they just want to damn the risk due to the fact that they feel it give them satisfaction.So people smoke because of the cold weather in their countries especially in the cold environment of iceland,russia, canada, usa, scotland etc
