Questions About Low-Tar Cigarettes

I question the validity of the statement that low-tar cigarettes are just as unhealthy as high-tar cigarettes [“‘Light’ Cigarettes Don’t Cut Health Risks, Study Says,” Nov. 28].

If this logic were valid, then one sleeping pill would be as deadly as 100 sleeping pills!

Also, how does one inhale “more deeply?” Either one inhales all the way into the lungs, or one doesn’t.
