Nicotine not unhealthy, it's the smoke only?
I read on a couple of websites that with smoking, it's not the nicotine that harms your health at all, that it's just the smoke itself and the toxins in cigarettes. I always thought and have read that it's both the nicotine and smoke that's harmful. I'm reading now on a few sites that it's only the smoke that hurts your health, and that nicotine alone if anything is good for your health. Of course you can't believe what you read on every site and that it can be hard to determine which sites are more true or not. So what are some of y'all opinions on this?
