Cannabis and schizophrenia?

I was going to write about a recent study that purports to claim that smoking pot causes schizophrenia that’s been making the rounds lately. Unfortunately (or fortunately, depending on how you see it), this week’s host of the Skeptics’ Circle, Mark Hoofnagle, beat me to it.

Can you say, “Correlation does not necessarily equal causation”?

The reporters who hyped the study and the investigators who enabled them should repeat this 100 times. Maybe it’ll sink in.
