In brief: Maybe

Despite a fair amount of study, nobody's been able to show a cancer risk.
Perhaps this is because people don't smoke nearly so much of the stuff as they do cigarettes. Unfounded scare-talk about this drug, which is becoming legal in parts of the us, tends to erode the effectiveness of real warnings about the true dangers of meth, cocaine, heroin, and the others. Still, why take a drug to be silly?

Good answer. One reason may be that THC & CBD actually have anti-cancer properties- see http://www.collective-evolution.com/2013/08/23/20-medical-studies-that-prove-cannabis-can-cure-cancer/ (I don't like the title of this article but it does have many good links to quality studies).

Exactly. Thanks, Dr. Baker!

My understanding is that smoking marijuana is not proven to cure cancer. However certain non-psychoactive cannabinoids are being researched for their anti-tumor properties.
