What to do if i have some loose tobacco from some old cigars. any ideas what i could use it for?

It works well as a: Good filler for garbage cans. Throw it away. If you are still smoking, get help and stop. Cigar tobacco has very high levels of carcinogenic tars, and many cigar smokers inhale in addition. It is associated with head and neck cancer, as well as potential heart and lung problems if you inhale. An occasional cigar may not do much harm, but there is nothing healthy you can do with loose tobacco.
