>>15758615It's not the nicotine in cigarettes that's the problem it's the particulate matter in smoke. The little tiny bits that get into your lungs and get surrounded by fibrous tissue that can turn into cancer. The thing they never tell you is that cigarette smoke is not special, any kind of particulate matter does this. Maybe you've heard of asbestos? Or black lung from coal miners? Or anyone working in any capacity around dust or smoke. Recently they've even been able to link lung cancer to Craftsman and Carpenters who spend a lot of time sanding wood.
Did you know that people who burn incense in their home have the exact same rate of lung cancer as heavy cigarette smokers? Cigar smokers barely register for increased incidence of mouth, throat or tongue cancer. Pipe smokers actually have tiny bit LOWER incidence of cancer vs non smokers. People who use nicotine in any form regularly have about 20% higher testosterone than non users. Nicotine is also known to protect against some progressive diseases so well that it's still prescribed by doctors for things like Alzheimer's, not only will nicotine prevent the degradation caused by Alzheimer's but it will actually help people recover slightly to moderately, and as far as I know it's the only thing that will actually reverse the process.
