It's horrid, and 'snusare' (those who 'snus') are scum of the earth (j/k). It's definately not "most" who use it but it does have its community. Little bags of tobacco made of like tea bag sort of material but a bit stronger, in all sorts of flavours or not flavoured.

Andrew Huberman has done a lot of material on nicotine - it's got a lot of benefits - namely for focus, but unfortunately most delivery methods cause death/disease/mutations of DNA. Would recommend anyone taking nicotine lozenges if you did want nicotine through fairly benign method of delivery to obtain its benefits, or to come off smoking or vaping (can get about 30 for something like £2 in Lidl). However it is a vasoconstrictor no matter how you take it.
