Tobacco is high in nicotine, tar and additives. hookah tobacco contains 0,05% nicotine and no tar. In fact, I stopped smoking at the doctor's recommendation. The reason is that I became ill with COPD. But I keep smoking hookah cigarettes. I see a respiratory doctor every month. My lungs are improving well even though I keep smoking hookah cigarettes. My lung function was 50% a year ago, but now it is almost 100%. My vital capacity is 20 years younger than my age.
