That chart represents the current drug scheduling, it wasn't saying that cannabis is more or less harmful just that it's unscheduled.

And in no part of the article does it suggest that they would make alcohol illegal. It points out the oppossite actually.

"That's not to say there's any argument that alcohol should be banned but it does give one a feel for the relative harm".

It's good to know that at least some people in some other government have their heads on straight. I hope they get a new scheduling system through, and I hope that the rest of the world follows their lead if they do it.
