So I went to local vape shop for a cloud competition the other day, and everyone who wanted to compete had to buy something to enter. Which sucks cause the shop I work at and every other competition I've been to does not require this, but I digress. I bought some 22g nichrome wire for the first time because I haven't seen nichrome in very many shops. I just recently found out that there is nickel in nichrome. I know vapeing on nickel wire is bad unless on a temperature controlled device, but I haven't seen anyone say to not use nichrome wire due to the nickel contents. Is the nickel contents dangerous at all or is there nothing to worry about? Also what's the recommended life of the coil?
