You feel 2 IQ points?

Even proponents of IQ tests admit they have a margin of error 3-5 points. Meaning you can swing on IQ tests beyond this threshold on the same day.

I'm guessing bad sleep or missing a meal the night before will swing your IQ significantly more than 2 points.

Well I’m being glib. But I do feel that smoking weed from an early age for decades has not been a cognitive benefit.
