yes that is true....there are (supposedly) a lot of things that cause cancer now but i was just answering your question....i could have also answered it....."because some people feel like the drug is taking over their lives"......."because smoking has lost its fun"........."because my medical problem has been cured and there is no need for me to smoke it anymore"......i dont know....there are lots of reasons really

but i hope you all have a HAPPY CHRISTMAS
