While stomatitis nicotina that is caused by heat is not a premaligant condition (i.e. it does not carry an increased risk of transformation to oral cancer), the condition that is caused by reverse smoking is premalignant.  The condition is uncommon.It occurs usually in elderly males who have a history of heavy pipe smoking, but it also can occur in cigar or cigarette smokers.The condition was once common, but has become more rare as habits such as pipe and cigar smoking have decreased in popularity.
