I don't know myself Jaga. Stands to reason anything you burn produces alot of bad things. Here's a clip of a comparison between tobacco smoke and weed, Erowids Vaults,, great site for tons of information on about anything', has a read,
From: Institute of Medicine, Marijuana and Health, Washington,D.C.
National Academy Press, 1988
"The smoke from any burning plant contains hundreds of chemicals that may have biological effects . . ."
"Cannabis smoke is similar to tobacco smoke in that it is a mixture of very small particles and a gas-vapor phase. Both the particulate and vapor phases contain many identified and probably some still unidentified constituents that, based on clinical experience with tobacco smoke, must be assumed to be potentially harmful. The amounts of some materials in tobacco cigarete and marijuana cigarette smoke are compared in Table 3. Toxic substances, such as carbon monoxide, hydrogen cyanide, and nitrosamines occur in similar concentrations in tobacco and marijuana smoke; so do the amounts of particulate material known collectively as "tars"."

I did a fast read in just what we exhale when we smoke. I think if the plants could they wood run.... Not sure if this makes sense but shows all the same bad shit we get outta cigarette, is in a joint except the nicotine and one other. Very little co2. But I've been doing it all my life. Well I'm off to bed,,,, Keepem Green
