Lighter fluid is really not necessary for starting a charcoal grill or smoker. With a charcoal chimney and a few pieces of cardboard you can achieve the same smoke and fire without the lighter fluid (and without the odor).
Simply add lump charcoal to the top of the chimney and add some corrugated cardboard either in the top or in the chamber below. It doesn't take much. Three or four 3 inch strips of cardboard will likely be plenty. I do this inside the grill or smoker for safety. Always remember: safety first.
