I'm a person who enjoys a pipe or a cigar once a month. I smoke alone on my balcony, so the smoke dissipates in the wind quickly and doesn't seem to bother anyone else. Any health effects incurred on me, I'm sure it's not as bad as smoking a pack of cigarettes a day. I don't even inhale the smoke (with pipes and cigars you are not supposed to inhale, as I will explain below) so the health risks are even less. Given these, why would you want to take this small pleasure away from me?
Cigars and pipes are not as addictive as cigarettes, and there is a reason for that. Cigarettes are designed to be inhaled. Their smoke is engineered to be more acidic, with additives to the tobacco and such. The acidic smoke is more readily absorbed by the lungs. Pipe and cigar smoke on the other hand is more alkaline in its nature. It is not absorbed well by the lungs. Instead, it is more readily absorbed by the mouth's mucosal membranes. Therefore you don't inhale cigar & pipe smoke. The result of all this is a major difference in the smoking experience. With cigarettes, you get an intense nicotine spike that lasts 5 minutes and then leaves you unsatisfied and wanting more. (The surface area of lung's absorbing membranes is a lot more than the mouth's, as you would expect, hence the intense nicotine spike.) With pipes & cigars, you get a slow and steady absorption of nicotine for an hour or so. It is relaxing and meditative. And you don't feel like having another cigar immediately after, since you are already left satisfied. I have been enjoying my once-a-month balcony smoking sessions for 3 years now. I have no feelings of craving or addiction. If I was smoking cigarettes, I highly doubt I would be able to enjoy one once a month. Instead, I would end up smoking two packs of cigarettes a day.
You may say let's just ban cigarettes then. Well, prohibition has worked so well in its history after all. Look at how nobody uses alcohol or drugs anymore, since we banned them back in the days...
Cigarette use is already in the decline. Instead of taking completely useless prohibitionary measures, if we wait long enough, cigarette use will be completely replaced by vaper use. And there will be the occasional esoteric cigar & pipe smoker like me, who quietly enjoys his cigar in his balcony, porch, or at the local tobacconist.
