Can smoking pipe tobacco in cigarette form be dangerous or make you sick?

Good question, seeing that I am actually now sick and coughing up a lung after smoking pipe tobacco cigarettes for only two days. I attempted avoiding the high price of Marlboros at the counter, but I am back to paying my high taxes like everyone else. I can't describe how uncomfortable my chest feels right now after smoking pipe tobacco cigarettes...in short it is something I will never do again. I would imagine that each person has a different experience though. I did not see any problems until smoking about 40 pipe tobacco cigarettes, then I was pretty congested.
