Smoking a cigarette, cigar, pipe, Shisha, Huqua, and the other uses of tobacco like tobacco sniffling and chewing tobacco are all addictive and dangerous. The nicotine that is present in a tobacco smoke is the prime cause of addiction as it increases the brain levels of chemicals such as Endorphine and Dopamine.

A tobacco smoke is consists of more or less 4, 000 chemicals, wherein 200 of them are known to be poisonous, and 60 are cancer causing.

The risk of having a heart attack becomes higher when a person continues to smoke for a long time. Those who consume a pack on a daily basis have two times risk to have a heart attack compared to non-smokers.
