There are a few things to consider about cigarettes that a lot of people don't seem to realize. Firstly, 95+% of cigarette brands and other so-called 'tobacco' products just aren't
really tobacco. A good percentage of what is in a cigarette is homogenized or "reconstituted tobacco"; they take the sweepings from the floor and other left overs: dust, stems and low grade leaf parts that could be a decade old, blend it to a pulp, press it into a sheet and shred it.
Then there is the "expanded tobacco", made with leaf that is doused in ammonia and freon, then freeze-dried. This increases the finished volume of tobacco they can get out of the same amount of material.
Then there are the
599 additives that the FDA has actually approved for these bastards to adulterate the recon with. Despite all of this, everybody turns around and says tobacco causes cancer, so smoking causes cancer and thus cannabis
must have the potential cause it, too.
But, wait a minute...there is also
smokeless tobacco: snuff, dip, chewing tobacco products. These products are also very likely to cause oral, esophageal and other kinds of cancer with prolonged use. There is absolutely
no smoke involved here...and yet, cancer! I know of no other herbal materials that could cause a cancerous lesion to develop if you constantly put a wad of it between your lip and gum line.
And I am surprised more people don't catch on to this, and the fact that tobacco grown in the United States (and likely many other places) is grown with cheap phosphate fertilizers that are derived from mined apatite and contaminated with radium, lead 210 and polonium 210 (these are radioactive).
If you do a little research and come up with lists of the components that are found in mainstream tobacco smoke (not just the list of the additives) you will see polonium 210 and various other horrible substances listed there.

I used to try to explain this to people all the time, so many of them refused to consider it and many more just seemed to pretend to agree...while they took another drag. Smoke your cigarettes and die like the government wants you too, kids!
