Q5 If it is the kind of tobacco not to smoke, aren't the worries about cancer needed? A A snuff, a chewing tobacco, etc. have some which do not necessarily require smoking in tobacco. It is the method of absorbing nicotine on the membrane of a mouth or a nose. If it is this method, it is not necessary to take in the Benzpyrene in the tar contained in the smoke of tobacco. Only nicotine can be enjoyed purely and it seems to be also a rational method. But, this way leads to superfluous ingestion of nicotine. Moreover, ingredients other than nicotine are also taken in through membrane, and it has a bad influence on the body. Even if it uses a snuff and a chewing tobacco, the symptoms of cancer may develop. There is also a report rather referred to as being what is more dangerous than ordinary smoking.
