Cannabis VS Tobacco

Overview

Cannabis contains THC (Tetrahydrocannabinol).

THC is a bronchial dilator, which means it works like a cough drop and opens up your lungs, which aids clearance of smoke and dirt. Nicotine does just the opposite; it makes your lungs bunch up and makes it harder to cough anything up.
 
 Scientists do not really know what it is that causes malignant lung cancer in tobacco. Many think it may be a substance known as Lead 210.

Of course, there are many other theories as to what does cause cancer, but if this is true, it is easy to see why no case of lung cancer resulting from marijuana use alone has ever been documented, because tobacco contains much more of this substance than cannabis.
