Your premise is incorrect. There is much written about the dangers of a single cigarette, and the discussion is included in some of the sforim about smoking in halacha. It is without any shadow of a doubt that smoking even a single cigarette is assur. I urge you to educate yourself before making proclamations. Before I ever allowed myself to discuss the subject, I did extensive study of the medical research, collected the writings from the gedolei haposkim, and discussed the issues intensely with several rabbonim who assured me that I was reading the issues correctly. perhaps I qualify as an expert on the subject, but I will not adopt that mantle. I am not afraid to make a statement that is fully supported by halacha, al pi gedolei haposkim of today’s generation.
