Answer 1

There are less harmuful alternatives, like iqos which is device that heats up tobacco instead of burning it, but they are still less healthy than not smoking at all.

Problem is that the key ingredient in cigarettes, nicotine, is on itself harmful and toxic. So even if you remove tar, carbon monoxide etc., there is still nicotine present. If you remove nicotine, then why even smoke at all?
