Once again- Alaska has a long time love-hate relationship with that leaf- and, there are a great many pot activists that make a big point of NOT smoking tobacco- it is a regular movement within the culture kind of thing.
Scubatim- the sample can easily be big enough and be found if there were indications that pot caused lung cancer 20 years earlier than tobacco- we would have seen the epidemic by now. There are very few lung cancers that don't have an indicator of what is causing it- asbestos, tobaco, etc. Oh, possibly agent orange and things like that (I had a friend, one that I listed, that could also be an agent orange deal too- he picked up smoking in the military, smoked for 20 years, quite 20 years ago- and then died from lung cancer. He was pretty heavily exposed to agent orange though.
That being said- there is way too many non-tobacco smoking pot smokers out there for us not to notice a trend- way too many.
So, just to see if I understand you, cancers contain signatures that can point at what caused the cancer?
Okay- let me put it this way- right now, we have around 450k people dying of smoking related illness every year. We also have some big names, like Bob Marley- that died of cancer-
so what you have is an epidemic when talking about smoking related illness. In a sample that large, it is very easy to seperate out non-smokers from smokers, and to find a control and study group of non-tobacco smoking pot smokers and tobacco users.
What the study says is that weed causes cancers earlier and is more cancer causing than cigarettes. Nicotene seems to be the major cause- something not found in marijuana smoke.
when you have over a million people every two years, and millions per year globally, yes, it would be quite easy to seperate the two types of smokers out- very easy.
There would be emphysema, COPD, all the indicators that tobacco have right now.
And there would be a plethora of evidence and studies showing the linkage of the COPD related to marijuana smoking.
For instance- I type in "marijuna causes cancer" in Pub-med- the main clearing house for all studies, around the world, that are in accepted, peer-reviewed journals of science- I get 21 hits:
http://www.ncbi.nlm.nih.gov/sites/entrezThe most that any suggest is that smoking crack and marijuna or other illicit non-tobacco drugs can cause the same pre-cancerous conditions to the esophogial epithelial cells- ususally there is an thickining of the epithelial cells from constant smoke inhalation- you get the same thing from Fire fighters and those that are exposed to constant cooking smoke etc- any smoke will cause that, if you are exposed enough.
Here is a study dealing with lung injury due to illicit substance abuse:
http://www.ncbi.nlm.nih.gov/pubmed/2190420..._RVAbstractPlusOkay- now on to tobacco 2626 entries on the same search guidelines:
http://www.ncbi.nlm.nih.gov/sites/entrezNow- if you read some of those studies- you will note that marijuana is the second most smoked substance on earth.
Ya, there would be a "orgy of evidence" if it had the same negative health indicators that tobacco does. Also- Weed smoking and hashish smoking has been available to western civilization longer than tobacco, tobacco being a "new world" product, and weed being all over the world for a long time.
So we would have not seen the huge jump in ill health effects from tobacco, because they would have been there all along due to weed and hashish smoking.
Ya, it is very logical to say that marijuana doesn't cause the epidemic of bad health things caused by tobacco.
Not any real hard evidence of cancer related to marijuana like there is with tobacco.
