so this is my smoker that I got operational not to long ago and my concern after thinking hard about it (and I proably produced more smoke than this does) is that I bought the metal, welded it together, did a test run with it. Is there anything on the metal that I should worry about getting off before feeding anyone meat from this thing..is there anything that is gonna leach out of the metal when heated or is it good to go after a couple of times of heating..
