I've gotten into the habit of changing the cotton in my coils often. Once it gets black I have to think it's sending carcinogens up with the vapor.
Also, what about super-high watts and dry hits? Could these pose potential health risks? I don't see the point in running coils over 30w unless you have a multiple coil setup or nickel. People in youtube reviews crank everything sub-ohm way up.
