What source is there for this proposition?  AFAIK all the examples
given for this drash on "ushmor nafshecha me'od" are about taking
risks of immediate death.  I don't know where people derive an issur
on smoking, which merely increases the likelihood of a life-shortening
illness at some future time, let alone a positive chiyuv to do things
that increase the likelihood of a longer life.
