First, breathe in through your nose. The nose is more fragile than the throat. There are many olfactory synapses in it, and snuff is a granular thing that irritates the nose very much. A novice like me feels the most obvious. A runny nose hurts my nose.

Second, it is relatively poor hygiene. I can't put it on the table and get my hands dirty. When I put the table on it, it was not clean. The plate in the plate is not clean. Sometimes when I inhale snuff, dust is inhaled. I have been worried about whether it will cause rhinitis infection or something, but I can't stop it. Very refreshing. Mainly because I have smoked toilet water myself before, haha.

Third, indecent, sometimes people will think that you are an addict. Snuff powder makes you feel dirty everywhere, difficult to clean up, and there are many boogers. It's really uncomfortable to have too much booger. It's black when you wipe your nose. A runny nose or something.

Fourth, it is unknown whether it will affect the sensitivity of the nose, but I think it should, because snuff usually adds a lot of essence or Chinese herbal medicine and has an aromatic smell. After smoking, the aromatic smell can not be dispersed for a long time, and some snuff particles will remain in the depths of the nose. Although they will be absorbed, too much coverage may also affect the sense of smell.

Finally, regarding whether it is carcinogenic, in fact, many factors can lead to cancer now, and too much stimulation can lead to cell mutation in a certain line, including an old man who often hurts his esophagus and mouth because he likes to drink soup and gets esophageal cancer. At present, because snuff is nonflammable, tar and carbon monoxide, two high carcinogens, will not be produced. Compared with cigarettes, the harm is definitely much less. There is no specific literature to show that snuff will definitely cause cancer. At least, there are not many reports about the carcinogenicity of snuff, and most of them are unclear. It may be a carcinogenic factor, so it is a relatively healthy way of recreation and nicotine intake. As for whether nicotine causes cancer, please go online Baidu yourself, so I won't go into details here.

Generally speaking, snuff is a healthy pastime. In addition, some snuff is white snuff without tobacco, all of which are herbs. Anyway, it's not a scourge, but it depends on people.
