Those aren't the right kind of questions. How about: Is prohibition good for society? Who is benefiting from prohibition? Should people be allowed to willfully consume drugs of their choosing?

To answer your question, I think most people would agree that it's less "risky" than alcohol, but risk is a hard thing to quantify. The reason there's so much pro-marijuana on the internets probably has less to do with marijuana usage and more to do with the free, open, and evidence-based nature of online communities.

I completely respect the freedom of choice you are referring to in your questions but I am genuinely interested in finding out about marijuana's health risks.

Just like risk is a hard thing to quantify, so is "right kind of questions" hard to define. :)

Given a world in which we are free to choose, as much of the US is becoming, these are the right questions to ask.
