So I smoked for a good bit, never vaped but the principle is the same.
Swedish Snus.
Stuff is fantastic. Personally I think purely vitamin N gets a bad wrap, and by itself is no more harmful than caffeine is albeit admittedly more addictive. Snus has been studied quite a bit, and has shown to have nearly zero increase health risks vs the average non smoker. It is like a nicotene pouch, lozenge, or patch in that it is a N delivery device but using a method similar to nic salt pouches like Zyn, but is far older of a process. It is spitless, can be had in a variety of flavors, and I love it very much.
Be aware you'll be trading one habit for another, but vs smoking or vaping it is leagues better and has kicked the habit for many people. Just don't be a retard that buzz chases. You can buy Siberia snus that has insane amounts of N, but most people stay with the 8mg per pouch normal portions vs the crazy high nic stuff.
