I should start by saying that i don't condone smoking, and if your not already a smoker i don't recommend starting. Now with that said, but if you are, your going to keep doing it so listen, tobacco is a natural product of the earth and natives have used if for thousands of years for various things, it is not the tobacco that is bad for you it is all the chemicals and additives that are added to it while mass producing it and all the chemicals that are added to the filters that your body can't deal with, hence the phlem the coughing scratchy throat, all caused by the additives added to the tobacco and filters, all unnatural and that is what hurts your body. so if you insist on smoking i recommend natural tobacco that can be purchased in pouches that are organic or just natural 100% additive free just natural tobacco, just like processed food is no good for you because of the same factors so you eat natural or organic, same care should be used with your tobacco.
