Is smoking forbidden, along with citing rational and medical evidence to refute the misconception that prohibition only applies when its harms reach 70%?

This issue is not a matter of dispute among specialists. The mentioned percentage for the considered harm in prohibiting smoking has no evidence, nor did it come from a specialist. The matter does not go beyond blameworthy disputation, due to the clarity of the issue and the agreement of international medical organizations and institutions on the harm of all types of smoking and the urging to quit it. The questioner can refer to a specialized research paper or book to ascertain the medical facts and scientific statistics.
