Snuff is a form of finely ground smokeless tobacco that many enjoy today as an alternative to cigarettes. Many people choose snuff as a means to gradually quit tobacco products. Others prefer a smokeless method of consuming tobacco, and want to minimize secondhand smoke exposure to those around them. There are many ways to use nasal snuff. However, snuff contains nicotine and is therefore addicting. While many believe snuff to be less taxing on your health than tobacco, there are many health risks associated with the use of nasal snuff.
A face mask as the name suggests fits over the face. The extent to which the face is covered depends on the type/purpose of the face mask. A simple face mask fits over the nose and mouth with open side ports to allow air to enter and dilute the oxygen as well as allow the escape of carbon dioxide. The mask is attached via an elastic strap which fits behind the head and over the ears with the end of the tubing attached to an oxygen source. A face mask allows oxygen delivery via either the nose or mouth so is suitable for nose and or mouth breathers.
