For a while it was unclear if the link between cannabis and psychosis was correlation or causation, but causation was ultimately established. It seems to be a relatively small percentage of the population that experience such things, but that's largely the same part of the population prone to heavy, chronic cannabis consumption in the first place.

So I just wanted to add that for a subset of the population, the risks are several orders of magnitude more serious than "lost a few IQ points", as many people are not able to resume normal life (nor indeed, a normal experience of reality) after a psychotic experience.

That being said, I do support legalization, since the alternatives are worse. I just also support people being well informed, and aware that while they're probably not in that 2%, there's only one way to find out, and you really, really don't want to find out.
