Good question on what I would do? First I am trying to become prepared-not scared. I am buying a mod so I can obtain normal lithium batteries. Also, I am now getting into DIY. If I have to I will extract nicotine from whatever source I can. I do believe nicotine base will be still available. I think the premixed would not be available if a ban was imposed. As long as I can obtain menthol crystals I will be fine. The flavoring's will be available. Pg/vg available as well. So I am really not worried at all.
