¿Does Smoking contribute to the global warming?

When fabrics produce cigars, (you may now that the fabrics pollute more than when they produce cigars) they use toxic substances and  when people smoke them they absorb the toxic substances and the gases ; then they are expelled to the atmospher but you may find this hard to believe if you're standing near a group of chain smokers, but most scientists think that the amounts of carbon dioxide and other pollutants in cigarette smoke have, at most, a negligible effect on the climate. 

But the smoky end-product is not the entire story. Tobacco must be grown, and that process puts a serious hit on the environment. The plant itself is very demanding, absorbing six times as much potassium from the soil as most crops do. Farmers in some undeveloped nations grow tobacco until the soil is useless and then clear-cut forests for fresh land. In those areas, 600 million trees are cut down and burnt annually to dry and cure tobacco leaves. Additionally, four miles of paper an hour is used to wrap and package cigarettes. Setting aside the pollution generated from manufacturing cigarettes, just losing this many carbon-dioxide-absorbing trees leaves at least 22 million net tons of CO2 in the atmosphere, it is equivalent to burning 2.8 billion gallons of gasoline.

The damage isn't confined to the air, either. According to common estimates, tobacco companies produce 5.5 trillion cigarettes every year—approximately 900 for each person in the world. Of those, 4.5 trillion have non-biodegradable filters that are tossed away. Cigarette butts require months or even years to break down, releasing almost 600 chemicals into the soil.
