In Scandinavia two fifths of the population chews tobacco. This custom, however, is mostly male and few women chew, except Eskimo.
Statistically, it has been proven that chewing or snowing tobacco can cause serious health problems. Among others, the likelihood of the onset of oral cancer increases considerably. Studies indicate that a third of the nicotine that is taken when esnifarse is ingested along with txistu. If tobacco is chewed, the proportion of nicotine ingested reaches half. The other part is filtered to the blood through the tissues of the mouth. Due to the ingestion of much of the nicotine, consumers tend to have stomach problems.
Therefore, the problems generated by tobacco are not limited only to tobacco consumption.
