Like tobacco smoke, marijuana smoke contains harmful chemicals, including hydrogen cyanide, aromatic and nitrogen oxides. These all can cause emphysema. Marijuana smokers are also exposed to total particulate matter(TPM) or tar, a chemical found in tobacco smoke. Tar is another culprit to blame for increased cases of emphysema among marijuana smokers.
Why The Effects Would Be Any Different
While marijuana smoke and tobacco smoke share some harmful chemicals, the former contains higher concentrations of the chemicals than the latter. This means marijuana smoke can cause a lot of damage than tobacco smoke.
