As I said in a earlier thread I am wanting to use vaping to help kick a smokeless tobacco addiction. I have a couple more questions... 1. What vaporizer should I buy to run higher nicotine levels? I bought a Kanger subvod subohm pen but I found out the hard way I shouldn't have since it's not good for the higher nicotine levels. 2. Once I have the correct vape can can I use it to switch in between nic salts and regular e juice?
