Are these articles true?

[Nosferatu]

I was researching on cannabis when I came across this worrisome set of articles. They state many studies and the reason I am worried is because they also cover some benefits and good studies on it. Look at this article and there's 4 or 5 more you can look at by clicking the other ones on the right. Am I just really high or is this a propaganda site or what?

I read the first article (from 2009), and found this part interesting:

"Marijuana smoke caused significantly more damage to cells and DNA than tobacco smoke, the researchers note. However, tobacco smoke caused chromosome damage while marijuana did not."

I believe it is true that any smoke is harmful for the human body, so the first article would be accurate, IMO. Good reason to vaporize 100% of the time.

I'm not sure about the accuracy of the second article from 2008.
