Please help................?

What happens when a smoker gets a cold? I am a smoker and I have a bad cold. My lungs are full of congestion and I'm having a time getting them to clear up. I know it takes time but they are just so congested! They are filled up. Anyways, I smoke anywhere from 6-10 HERBAL cigarettes a day. They are tobacco free and nicotine free. They do contain TAR and CARBON MONOXIDE. They have just as much tar and carbon monoxide and dangerous chemicals as a regular cigarette. The only difference is the nicotine. What can smoking with a cold do to you? Tell me all the possible things. Thanks!
