So Ive recently developed a bit of a smoking habit, and am still sort of feeling my way around tobacco products. Ive tried a whole slew of different cigarettes and a few different types of rolling tobacco. Im trying to pick a "favorite" type of tobacco, but Im so lost. I know Newports and other (all?) menthalated cigarettes have some really harsh things in them (like plexiglass), and I know that in general rolling your own cigarettes is worse for you. My lungs arent the greatest lungs out there (I grew up with asthma, so was generally non-athletic but not out of shape. I cant really run a mile...), and I was just curious what cigarettes/rolling tobaccos are better/worse for you? Of course by better Im speaking in purely relativistic terms. What are the things that hurt you the most in cigarettes? What does "light" mean? Is there a difference in how good 100's are as opposed to regulars? Are American Spirits (blech) significantly less toxic? Maybe you can come up with some of your own questions.. and subsequently answer them : ) (or just post them. Id like to get some discussion on tobacco going here) Does anyone know of any studies that were done? I googled some stuff but came up with nothing.
